:TEAPAC Ver 7.80 25APR07

Build 01 - 08OCT07

>PRESYNCHRO: Synchro Ver 7 1-File CSV Format Is Supported for Export and Import.

When Synchro Ver 7 is involved, the UTDF file format used for both Export and Import from/to PRESYNCHRO is now the new 1-file CSV UTDF format. This is a vastly easier format to work with at the user level, providing the ability to automatically launch Synchro with this file already open for Export, and the need to create only a single file when saving a UTDF file from Synchro to be Imported by PRESYNCHRO.

Build 00 - 08JUN07

>Long File Names and Longer Path Names Implemented, Plus New File Format.

All aspects of TEAPAC data file storage, including SCENARIO condition files, have been extended so that file names can have as many as 70 characters in their names, and file path names can have as many as 180 characters, both including upper or lower case characters and spaces. Since SCENARIO condition files and certain file switch options can add as many as 6 characters to file names, it is best if user-entered names are no more than 64 characters.

 

A new, higher capacity data file format with a new file extension (.tpc) has been introduced which will be used by default for all new files created by all TEAPAC programs. This format is text-based like the old .for format so it is still easy to see what is in a file, as well as write such files from other programs, but with a look to the future this format has line length maximums of 256 characters per line (254 useable) instead of the more limiting maximums of the .for format which had maximums of 128 characters per line (80 useable). The old format can still be read and written simply by continuing to use the .for extension, but users are encouraged to convert files to the new format simply by saving .for file with the new .tpc extension (then archive the .for files so they are not used by mistake). The long file names and paths mentioned above are valid for either extension.

>New User Discussion Forum Is Accessible Directly from the Help Menu.

The new User Discussion Forum which has been implemented for TEAPAC users and is available 24/7 for posting questions and searching through answers to previous questions can now be accessed directly from the Help menu of every TEAPAC program. The Forum can also be accessed directly using any internet browser at www.StrongConcepts.com/Forum.

>SIGNAL2000: HCS+ Export for Signalized and Unsignalized.

The EXPORT function has been updated to use the native HCS+ data file format (XML-based), and has been expanded to include exporting for both signalized and unsignalized intersections defined in the complete TEAPAC network of intersections. This is now the default for the Export function, but as before, older versions of HCS can still be exported to by using the file extensions specific to those versions.

>PRENETSIM: Direct Support for CORSIM Ver 6.

Direct support for the latest version of CORSIM, Version 6, has been implemented in PRENETSIM as the default condition. Continued support for older versions of CORSIM and NETSIM still exists by proper selections in the Options-Setup menu and the OUTPUT dialog.

>PRESYNCHRO: Direct Support for SYNCHRO Ver 7.

Direct support for the latest version of SYNCHRO, Version 7, has been implemented in PRESYNCHRO as the default condition using the CSV UTDF multi-file format. The DAT UTDF format is still used for Ver 5 Exports and Imports, but Ver 6 Exports and Imports have been converted from the DAT format to the CSV format so that intersection and street name information can be transferred to Ver 6 the same way it is handled in Ver 7.

>PRETSPPD: Direct Support for TSPPD Ver 7.

Direct support for the latest version of TSPPD, Version 7, has been implemented in PRESTSPPD as the default condition, and now intersection and street name information can be transferred to Ver 6 the same way it is handled in Ver 7.

:TEAPAC Ver 7.01 08SEP06

Build 07 - 25JAN07

Scroll down to 'Ver 7.00 07NOV05, Build 07 - 11NOV05' below for the major changes which were implemented for the original Visual TEAPAC release of this program.

>SCENARIO Program Makes its Debut.

SCENARIO is a new Visual TEAPAC program that can create multi-scenario data files either from scratch or from data files of earlier versions of TEAPAC. Users can 1) select from pre-defined typical scenario structures like multiple volume conditions or multiple timing plans, 2) create completely unique scenario conditions for their analyses, or 3) customize a pre-defined scenario structure to meet their specific needs. The primary advantage of using SCENARIO is that all the scenario data is saved without dangers of duplicated data which often occur when scenarios are managed by the typical use of File-SaveAs.
 


The SCENARIO program also functions as an automatic plugin for all other Visual TEAPAC programs so that each program automatically understands the SCENARIO file structure which has been created, and at no additional cost (see below).

SCENARIO can easily define both single-issue and multi-issue conditions, and any data dialog can be assigned or re-assigned to any defined issue for as many as five independent, mutually-exclusive Issues. 25 Conditions can be defined for each Issue. For example, a very common and simple single-issue scenario would be having multiple volume conditions for one or more intersections for which capacity analysis, intersection design and/or signal timing optimization would be needed. Other examples of a single-issue analysis could be multiple years of traffic count data for TURNS or WARRANTS, or multiple years or zones of land use for SITE's projected traffic estimation.

Multi-issue scenarios could be combinations of any of these, where the variation of one variable is independent of the others. Another example of a multi-issue scenario could be where one Issue is changing volumes based on the time-of-day and/or day-of-week while the other Issue is independently changing intersection geometrics which depend on differing funding possibilities.

>SCENARIO Support in All Visual TEAPAC Programs.

All Visual TEAPAC programs have been updated so that support for multi-issue data files created by SCENARIO is automatic and seamless. The SCENARIO program serves as a plugin to the other Visual TEAPAC programs so that they automatically support the SCENARIO-structured files for both File-Open and File-Save. A new File menu option labeled Get-Scenario-Case allows the user to select any of the Conditions for all of the Issues which have been created, and any subsequent changes to data which are made are automatically saved in the correct Condition files which have been defined. SCENARIO has also been added to all LinkTo menus so that SCENARIO is immediately available to modify the defined scenario structure, as necessitated by changing project assumptions.

>SIGNAL2000: Default Value for DESIGN Optimization Changed.

The default value for the DESIGN optimization control parameter has been changed from 0 to 1 so that a default optimization will now always generate a capacity analysis of the top-ranked phasing and cycle length combination without changing the default.

>Generic Enhancements Made to All Visual TEAPAC Programs.

A number of additional generic enhancements and fixes have been made to the original Ver 7.00 releases of Visual TEAPAC and are collectively included as Ver 7.01 Build 07. These are documented below. Ver 7.01 Build 07 changes are free updates for Ver 7.00 licenses.

Data entry dialogs that don't apply to dummy nodes have been modified so that if they are inadvertently displayed while pointing to a dummy node they will not display unpredictable values or cause the program to crash.

The LinkTo menu has been adjusted so that if no data file path has been defined it will attempt to use the program's file path, but will not crash if neither of these is defined. The file menu options for Open, SaveAs and IntoEdit have been adjusted similarly for the condition when no data path has been defined.

A bug has been fixed that could cause a crash when clicking within an output being displayed at a zoomed-out scale on some low-resolution monitors.

:TEAPAC Ver 7.00 07NOV05

Build 28 - 28AUG06

Scroll down to 'Ver 7.00 07NOV05, Build 07 - 11NOV05' below for the major changes which were implemented for the original Visual TEAPAC release of this program.

>V7.00.28: Generic Enhancements Made to All Visual TEAPAC Programs.

A number of generic enhancements and fixes have been made to the original Ver 7.00 releases of Visual TEAPAC and are collectively included as Ver 7.00 Build 28. These are documented below and use heading lines that begin with V7.00.28:. In addition, minor program-specific changes have been made, as summarized here and detailed in the program's own specific list of updates and changes. Ver 7.00 Build 28 changes are free updates for Ver 7.00 licenses.

>V7.00.28: Number of Access Drives Increased From 5 to 10 for SITE Computations.

The permitted number of driveways which provide access to a development area for SITE computations has been increased from 5 to 10 in all TEAPAC programs, allowing greater flexibility in modeling all driveways which may exist or be proposed for a development. Along with this change comes a quicker way of entering driveway locations by combining the intersection leg direction (N/E/S/W) with the node number of the drive, such as 1N or 132E.

>V7.00.28: Input Limit for VOLFACTORS Adjusted for Consistency with Save.

The largest VOLFACTOR which can be saved in a TEAPAC data file has always been 9.99, but it's been recently noticed that the input dialog error checking permitted factors as large as 20.0 without an error, resulting in subsequent problems if an attempt was made to save such an entry. The input error checking has been modified to match the save limitation to resolve this problem. At the same time, the discussion in the documentation has been modified to reflect the same precision of save accuracy to avoid any further confusion.

>V7.00.28: Multiple Copies of a Program Can Be Open Simultaneously Again.

The source of a problem which has recently prevented multiple copies of any given program from being open at the same time, such as when comparing alternatives side-by-side. This problem has been resolved and the ability to have multiple copies open simultaneously has been re-enabled.

>V7.00.28: Minor Fixes to Drag-and-Drop Network Interface.

An occasional problem connecting T-intersections properly when bend nodes were present in the network has been resolved. Build 21 versions of the programs would notify the user of the problem immediately upon creation of a link under these circumstances. If an earlier version was used to create the network, the problem is easily detected (if it exists) with the Analyze function in the new Coordinate System section of the Setup button dialog in the main window. the problem would manifest itself with upstream connections to the wrong node and/or incorrect distances. Creation of most T-intersections were not affected by this problem.

If an old TEAPAC data file saved from a program prior to Visual TEAPAC was opened using a LinkTo, drag-to or from a command line, a crash could result when an attempt was made by the program to update the Nodelist format to the new save format. This problem has been resolved.

Build 21 - 27JUL06

Scroll down to 'Ver 7.00 07NOV05, Build 07 - 11NOV05' below for the major changes which were implemented for the original Visual TEAPAC release of this program.

>V7.00.21: Generic Enhancements Made to All Visual TEAPAC Programs.

A number of generic enhancements and fixes have been made to the original Ver 7.00 releases of Visual TEAPAC and are collectively included as Ver 7.00 Build 21. These are documented below and use heading lines that begin with V7.00.21:. In addition, minor program-specific changes have been made, as summarized here and detailed in the program's own specific list of updates and changes. Ver 7.00 Build 21 changes are free updates for Ver 7.00 licenses.

>V7.00.21: New Coordinate System Management Features.

A new set of options to help manage the network coordinate system for any given data file has been added to all programs that use the Visual TEAPAC drag-and-drop network editing and display (all TEAPAC programs except NOSTOP, TED and TUTOR). The options appear in a new dialog which is displayed when the Coord Sys button is pressed in the network Setup dialog.

The Coordinate System Management dialog offers three main function - 1) to Analyze the current network for possible coding errors such as improperly-connected nodes and scaling issues, 2) to create a New Coordinate System by shifting and/or scaling the current coordinate system, and 3) to compute New Link Distances based on the current coordinate system. For the Analyze function, a percentage error can be input to define the threshold which identifies potential scaling problems between the coordinate system scale and each link's entered distance, and an option can be selected to check the approach angle of each intersection leg.

One of the motivations for this new option is to be able to identify and adjust network coordinate systems from older TEAPAC programs which exercised the option to specify the units of the coordinate system in something other than feet. Although this is still possible, it can be problematic with the new drag-and-drop Visual TEAPAC interface, and is not recommended. In combination with the new Manual Distance option described below and the functions of this new dialog, old coordinate systems can be easily converted for more predictable use under the new Visual TEAPAC methods.

>V7.00.21: New Manual Distance Option Added to NETWORK Dialog Entry.

A new option can be selected in the NETWORK dialog individually for any given link of the network that indicates that the distance entered for that link is intentionally inconsistent with the network coordinate system and apparent network scale. Links which have this option selected are specifically excluded from the computation of the average coordinate system scale used and reported in the network Analysis function described above. Although not recommended, selecting this option allows a link's distance to be inconsistent with the coordinate system without adversely affecting the management and checking of the rest of the network.

In addition to this option, the NETWORK dialog also shows the calculated link distance based on the coordinate system (and the average coordinate system scale, if not equal to 1.0), and if this calculated distance is outside of the allowed error specified in the Coordinate System Management dialog, it is displayed in red. The Manual Distance option status is also shown in all data summaries which include NETWORK data, and new distances which are required due to any network editing are now always based on the coordinate distance, unless a link is previously marked for Manual Distance.

>V7.00.21: Automatic Network Relationship Checks Made.

The new Analyze function of the Coordinate System Management dialog mentioned above is invoked automatically any time a data file is Opened or Saved, or any time NETWORK or NODELOCATION information is changed (either via drag-and-drop actions or direct keyboard entry), thereby giving immediate feedback when a network definition problem could be corrupting an analysis. The Analyze function is also invoked prior to other program functions which make significant use of the spatial arrangement of the network, such as Exporting in PRENETSIM, PRESYNCHRO and PRETSPPD and FindPaths in SITE.

>V7.00.21: Frequency of Automatic Update Check Can Be Set By User.

A new user entry can now be made which controls the number of days between automatic checks for program updates. The entry can be found in the Help-Check_For_Newer_Updates menu dialog. With this new feature, the maximum frequency of automatic checks is once per day, not every time the program is run. Automatic checks can be disabled by entering a frequency of 0 days, but this is not recommended (checking for updates every 10-30 days is recommended).

>V7.00.21: Improved Initial Zoom-All View for Large Coordinate Range.

The initial Zoom-All display for a network when a file is opened has been improved for all networks, especially those with a wide range of coordinates, such that the zoom level used is more appropriate for all combinations of networks and display resolutions.

>V7.00.21: Improved Network Editing Features.

A number of enhancements have been made to network editing functions to improve the response to various user actions, as follows. If a new link connection will over-write an existing leg of a node, the user is warned and given the option to select another leg or abort. If a new link creation is aborted for any reason, any new dummy nodes created as part of that process are deleted (including clicking on the network without dragging, now deleting the single node which was previously created). If a third leg is added to a bend node as part of a new link creation, the bend node is converted to a real node (and re-numbered accordingly). If deleting a node removes one leg of a bend node, the bend is converted to an external node. Default source movements for a new link which connects existing nodes with a diagonal are determined more reliably. Left-click can be used while in the Create New Link mode to select the current node.

>V7.00.21: Fixes to SIMULATION Dialog.

The 'Use TRANSYT or PASSER Actuated Model' option of the SIMULATION dialog is now both properly selectable without any error messages, and displayed properly in the dialog, and a random glitch which garbled part of the main window Network display when the SIMULATION dialog opened has been fixed.

>V7.00.21: Make Help File Useable When a Data File is Double-clicked.

A problem locating the .HLP file when a user data file was double-clicked in Windows Explorer to open it has been fixed.

>Program-Specific Updates Included in General Visual TEAPAC Update.

Several program-specific enhancements have also been made to individual programs, as listed below:

SIGNAL2000 -- for unopposed left turns, the right turn model is no longer used (as in previous HCM versions) since this condition is handled properly by the Ped-Bike model for left turns.

NOSTOP -- a better output display is provided in the unlikely event of an optimization result that has no solution.

All PRE-Processors -- check for problematic Offset entries that might crash a time-space diagram plot; display the new Manual Distance entry for NETWORK in the summary of data values.

PRETRANSYT -- improved correlation between Route and Nodelist/Subsystem entries.

PRENETSIM -- automatic network validation check before Export; fix problem simulating bend nodes between real and external nodes.

PRESYNCHRO -- automatic network validation check before Export; round imported offset values which are between 0.0 and 1.0 to maintain consistent units.

PRETSPPD -- automatic network validation check before Export; round imported offset values which are between 0.0 and 1.0 to maintain consistent units.

PRENOSTOP -- keep imported Offsets in proper range between 0.0 and 1.0 (sec/sec); more clear identification of an attempt to import results from a NOSTOP optimization with no solution; better calculation of SPLIT for Export when system cycle length is not the same as an intersection's current timings (eg, when doing a system cycle optimization).

SITE -- automatic network validation check before FindPaths; improved cumulation features, including better formatted output, better initialization which allows for a larger subsequent cumulated network, and improved documentation of cumulation procedures.

Build 14 - 20APR06

Scroll down to 'Ver 7.00 07NOV05, Build 07 - 11NOV05' below for the major changes which were implemented for the original Visual TEAPAC release of this program.

>V7.00.14: Generic Enhancements Made to All Visual TEAPAC Programs.

A number of generic enhancements and fixes have been made to the original Ver 7.00 release of Visual TEAPAC and are collectively included as Ver 7.00 Build 14. These are documented below and use heading lines that begin with V7.00.14:. In addition, minor program-specific changes have been made, as summarized here and detailed in the program's own specific list of updates and changes. Ver 7.00 Build 14 changes are free updates for Ver 7.00 licenses.

>V7.00.14: Color Selection Added to Options Menu.

The Options menu now provides a Colors option for selecting colors which are used when generating formatted output reports and the main window network display. Any selections made are retained and used during future program sessions. Most of the default colors for formatted output reports are taken from the user's desktop color scheme (DisplayProperties-Appearance), so changing the color scheme will automatically change the output colors used when the defaults are selected. All colors selected, including actual selections and defaults, are displayed in the Color management dialog produced by the Options-colors menu selection.

>V7.00.14: Browse Button Added to Select a Bitmap File.

A browse button has been added to the Network Display and Edit Management dialog which is displayed when the Setup button of the main window is pressed. This can be used to select a bitmap background file in the data file folder as an alternative to simply typing the file name in the entry field.

>V7.00.14: INTERSECTION Dialog Options Added.

The INTERSECTION dialog which is used to select the 'current' node has been significantly enhanced with several new features, as follows. A check box enables the inclusion of dummy nodes in the drop-down list so dummy nodes can be selected from the dialog; and nodes in the drop-down list can be ordered in any of three arrangements - the order they appear in the NODELIST, numeric order by node number, or alphabetic order by intersection description.

On a related note, the network display is now updated any time a new current intersection is selected, including when it is entered from the Manual Mode, when it is entered from file input, etc. Also, when a dummy node is selected as the current node, it is always highlighted in the network display, even when the zoom level is such that other dummy nodes are not displayed.

>V7.00.14: Option Added to Delete All References to Deleted Node.

When a node is deleted or cut from the network, either from the main window network display or from the NODELIST dialog, a prompt to verify the deletion is now always issued, and the prompt now includes a new option to include the deletion of all other references to the deleted node elsewhere in the network. The option to delete all references is pre-selected by default on each deletion, but can be de-selected in the prompt dialog box.

On a related note, the manipulation of nodes in the NODELIST dialog has been extended to include dummy nodes as well as real nodes, offering greater flexibility in managing the entire node list from this dialog. A problem with the Copy and Paste functions (to and from the clipboard) has also been fixed.

>V7.00.14: Improved Support for PDF Creation.

Difficulties producing PDF files for formatted output reports with certain PDF writers have been resolved.

>V7.00.14: Improved Constraint In Use of SUBSYSTEM Function.

The use of the drag function in the main window network display to create or edit a SUBSYSTEM has been constrained for better consistency with the allowed use of the SUBSYSTEM feature based on the program's licensed Usage Level. This prevents inadvertent setting of the SUBSYSTEM which then causes an error when opening a file which has this feature saved.

>V7.00.14: Maximum Link Length Increased from 9999 to 32000.

The maximum link length allowed by all TEAPAC programs has been increased from 9,999 feet (<2 miles) to 32,000 feet (> 6 miles), and a warning message is now issued if a link is created in the main window network display that exceeds this limit.

>V7.00.14: File-OpenMerge Function Enhanced.

The File-OpenMerge function has been enhanced in several ways, as follows. First, if a file being merged contains information about a bitmap file and its scaling, this information is ignored in deference to the bitmap/scaling information currently in effect in the program. The help strings for this function have also been updated, and the function is initialized more completely each time it is used to avoid overlap with responses to previous error situations.

>V7.00.14: Help File Formatting Restored to Previous Style.

The numbering of the indented paragraphs in the Notes section of Appendix B of the Help file has been restored, as appeared previously.

>V7.00.14: Minor Cleanups and Fixes Implemented.

A number of (mostly internal) cleanups and fixes have been implemented for more reliable operation of Visual TEAPAC programs. Most of these will not be noticeable to users, but a couple will resolve certain problems a few users have experienced. For example, opening an old TEAPAC data file which does not contain valid NODELOCATION entries for each intersection will not crash, and moving a bend node under certain conditions will not cause the program to close prematurely.

>Program-Specific Updates Included in General Visual TEAPAC Update.

Several program-specific enhancements have also been made to individual programs, as listed below:

SIGNAL2000 -- a new OUTPUT option called 'Input' has been added to include the Input Worksheet (only) with the Capacity Analysis Summary output report, and Critical v/c has been added to the top of the Capacity Analysis Summary output report.

SITE -- bend nodes can be omitted from the path list in PATHASSIGNMENT; bend nodes are automatically removed from paths created by the FINDPATHS function; long FINDPATH paths are now displayed from beginning to end in the main window network display; FINDPATHS responds better to missing or invalid network data; and column headings have been added to continuation pages for COMPUTE results.

PRETRANSYT -- remove the creation of an IOSPEC file which is no longer allowed by Rel 10.3 of TRANSYT7F.

PRENETSIM -- default pocket length is still 250 feet, but it is now limited to a value 60 feet less than the link length as an approximation of the effective link length which cannot be exceeded by a pocket length.

PRESYNCHRO -- fix problem with PLOT function if default list of nodes is used when dummy nodes are present.

PRETSPPD -- fix problem with PLOT function if default list of nodes is used when dummy nodes are present.

Build 07 - 11NOV05

>Visual TEAPAC - A Whole New Way of Seeing TEAPAC.

All 13 modules of the TEAPAC suite of programs have been upgraded to the Visual TEAPAC (Version 7) interface. Primarily, this means each program sports a much more visual input and output system to make entering and viewing data for the analysis network much easier and to make the resulting output reports clearer and easier to read. The general aspects of the two major enhancement areas, visual input and visual output, are described below, followed by the many other supporting enhancements that go along with the Visual TEAPAC upgrade.

When combined with the unparalleled 1-file, 1-click, 500-intersection, completely seamless data sharing introduced with each of the 13 TEAPAC2004 (Version 6) programs, Visual TEAPAC provides an unmatched experience of fully-integrated visual traffic engineering and traffic planning software. Read on for the details.

>Visual TEAPAC - Graphical Input and Display of Analysis Network.

All TEAPAC programs (except NOSTOP and TUTOR) now provide a drag-and-drop user interface as a way to create and/or display the study network in the main window of the program. The network can be drawn schematically or to precise scale with the aid of an underlying grid, or a bitmap can be displayed under the network to make drawing easy and/or display of the network more meaningful. The bitmap file can be an aerial photograph, a street map, as-built drawings, or any other such display which would be helpful, and this bitmap is exported to third-party program such as CORSIM and TRANSYT as permitted.

Streets can be drawn by clicking on the grid or scaled bitmap and dragging across the extent of the street section, creating analysis intersections where the new street segment crosses existing street segments. The Setup button can be used to identify the bitmap, scale the bitmap and establish an axis origin, either before the network is drawn or afterwards for pre-existing data files. Special display adjustment modes allow quick re-orientation to new bitmaps, such as when using higher-resolution bitmaps for a zoomed-in study area versus a regional area bitmap.

Dummy nodes are automatically created to orient external legs of intersections around the periphery of the study network, and internal dummy bend nodes are easily created for better network representation between analysis intersections. Proper treatment of all dummy nodes (externals and bends) are fully integrated into all of the TEAPAC application programs, as well as the eleven+ third-party programs to which TEAPAC analyses can be exported. Dummy nodes do not count against the maximum number of intersections allowed by each Usage Level.

Intersections and dummy nodes are easily moved within the network by simply dragging them across the grid or bitmap, with the option to freeze the associated link distances, or have them adjust automatically as they are moved.

The network view is easily adjusted with buttons for panning in eight directions, zoom in, zoom out, zoom all to show the entire network, and a rubber-band selection to outline the desired zoom-in area. The display of either the bitmap or the network is easily toggled on or off, as required, and the current intersection for subsequent dialog data entry or analysis is made by simply clicking the intersection. Intersections can also be selected by a right-click which opens a popup menu with all the data entry and data analysis dialogs immediately available, either in Normal View or Tabular View (use F3 to toggle the view). The popup menu also allows the renumbering or deletion of the selected node. Dragging a rubber-band selection box around a set of intersections can be used to define or add to (with Ctrl key) a subsystem of intersections for subsequent analysis.

The on-screen shortest-path FindPath assignment function of the SITE program is now performed in color directly on the main-window graphics network display, including the bitmap background, providing helpful visual cues while performing the assignment process.

The on-screen Startup Help? button provides immediate assistance for all of the functions described above. Visit www.StrongConcepts.com for examples of the new graphical input front-end now found in Visual TEAPAC.

>Visual TEAPAC - Enhanced Graphical Output Reporting.

All TEAPAC programs now feature enhanced, graphical output reporting for all results produced. Output reports now make full use of color and graphics drawing for arrows, phasing diagrams, permitted movements, time-space diagrams, intersection diagrams, cycle optimization graphs, daily count variation graphs, etc. All reports are printable on any color or black & white printer supported by Windows, including PDF writers. Any graphics output page can be copied to the clipboard as a bitmap so it can be pasted into other applications. The prior version's text-only results are still viewable alone or in parallel with the graphical results, and selected text can be copied to the clipboard or saved to a text file for subsequent use, as before. In Visual TEAPAC, you are no longer limited to the old, archaic, hard-to-read character graphics which was used when TEAPAC was originally created (what did your computer look like 30 years ago?).

All output reports use shades of color from the desktop theme/style setting to highlight the results, including report titles, report sub-sections, column headings and alternating output lines. The proportionally-spaced, sans-serif Tahoma font is used for easier readability, including right-justified numeric results in columns.

Viewing options include zoom in, zoom out, zoom all to see an entire page, rubber-band selection to zoom in, drag the page to scroll and click to re-center. Text strings can be searched for within one or many pages of results and multi-page results can be quickly scanned with controls to advance to the next or previous page, the next or previous report, or the beginning or end of all results.

Visit www.StrongConcepts.com for examples of the new graphical output back-end now found in Visual TEAPAC.

>Other Generic Enhancements Found in All Visual TEAPAC Programs.

Many other generic enhancements have been made to the Visual TEAPAC user interface which is now included in every TEAPAC program. These include:

-- Windows XP style buttons, drop-down lists, scroll windows, etc.
-- all Edit and Results menus can be accessed by right-click.
-- all demos allow at least 4 intersections to be entered and analyzed.
-- license keys are valid for any older version of the same program;
license info displays in Help-About, including site license address.
-- leading W removed from all program file names for easy recognition;
LinkTo and Menu looks for new name first, then old name with W, for
backward compatibility with older versions of other TEAPAC programs.
-- default node to renumber is the current node, not 0.
-- Startup Help button is located in main window and now in Help menu;
StartUp.txt can be modified by user with virtually unlimited size.
-- View-Network and Options-Graphics menu options have been removed.

>Program-Specific Enhancements Included in Visual TEAPAC Upgrade.

Many program-specific enhancements have also been made to individual programs, as listed below:

SIGNAL2000

Timings provided or optimized 'by movement' are displayed with a new ring-based display in the capacity analysis report. New options (TrapOk, MultiOk & Unrestricted) for the Permissives dialog allow both the analysis and optimization of two special-case permitted left turn conditions - the left turn trap and multi-turn-lane permitted operations. The message that displays each time an unsignalized intersection is skipped in an analysis can now be disabled. Warning messages that display when high turn percentages are encountered are automatically omitted when the sum of the turn percentages is 98% or higher, such as at T-intersections or special conditions with dummy through movements. Dummy nodes are skipped without any messages when all intersections are being analyzed, and dummy node conditions are reported in abbreviated form at the end of a Summary of Parameter Values produced for all intersections.

SIGNAL2000 output reports which are significantly enhanced by the new color-graphics results produced by Visual TEAPAC include: all phasing displays, clearly showing permitted movements and critical design movements, either in HCM 'by-phase' style or ring-based 'by-movement' style; the Capacity Analysis Summary boxes for each approach; and the intersection data summary diagram.

SITE

The FindPaths assignment function is now performed with color path display directly on the main window network/bitmap instead of a schematic network display in a separate window. The Assignment data entry is initialized like other intersection entries, either for the current intersections or for all intersections. Dummy node conditions are reported in abbreviated form at the end of the Summary of Parameter Values.

NOSTOP

The demo limits have been increased from 3 intersections to 6 and from 5 cycles to 7, with increments of 10 seconds instead of 30 seconds allowed, all to better illustrate the program's potential and to allow the sample problem of Chapter 2 of the on-screen manual to be entered. A new 6-intersection sample data file called NOSTOP.FOR has also been provided which exploits these new limits. Inappropriate errors which were issued when the Available dialog was used and when certain inputs for the Nonconcurrent dialog were used have been suppressed.

NOSTOP output reports which are significantly enhanced by the new color-graphics results produced by Visual TEAPAC include: the color-coded Efficiency versus Cycle graph; the full-color time-space diagram which show through phases and clearance intervals, directional offsets and band widths.

WARRANTS and TURNS

A new entry in the CountType dialog is provided which can be used to describe the count which was made for each intersection. 40 characters can be entered to describe the date, weather, count station, etc. and this information is listed in most output tabulations and analyses. Import of electronic count data also fills this field with available information from the count file, and the intersection description of the Intersection dialog is also filled. Except for a 1-intersection analysis, this information is no longer placed in the Project/Description/Note title entries which now apply generally to all intersections in the study network, not an individual intersection (as before). Dummy nodes in the network are now skipped for all tabulation and analysis functions without any message. The demo versions of the programs allow certain limited Conditions inputs to be made in order for the sample data files and example problem of Chapter 2 to be entered without error.

WARRANTS and TURNS output reports which are significantly enhanced by the new color-graphics results produced by Visual TEAPAC include: the plot of changes in daily traffic counts; and intersection peak volume diagrams.

All PRE-Processors

The new Permissives options for SIGNAL2000 are displayed and exported properly to all host programs. Dummy nodes are ignored for any PLOT or TIMINGS result, and bend nodes or unsignalized locations are ignored for any time-space PLOT. Node number entries for PLOT and TIMINGS are allowed up to the more recent upper bound of 999 instead of the older limit of 327. Various input error checks are skipped for dummy nodes, and dummy node conditions are reported in abbreviated form at the end of a Summary of Parameter Values produced for all intersections.

PRE-Processor output reports which are significantly enhanced by the new color-graphics results produced by Visual TEAPAC include: all phasing displays, clearly showing permitted movements, either in HCM 'by-phase' style or ring-based 'by-movement' style; and the full-color time-space diagram which shows all phases and clearance intervals, directional offsets and band widths.

PRETRANSYT

In addition to the above for all PRE-processors, dummy external nodes are omitted from the TRANSYT Export in order to minimize the number of intersections sent to TRANSYT (which has a maximum of 100 intersections), and links with bend nodes are merged into a single link for the same reason.

PREPASSR

In addition to the above for all PRE-processors, dummy external nodes are omitted from the PASSER Export in order to minimize the number of intersections sent to PASSER (which has a maximum of 20 intersections), and links with bend nodes and/or unsignalized intersections are merged into a single link for the same reason.

PRENETSIM

In addition to the above for all PRE-processors, if dummy external nodes are provided by the analysis network, these nodes and their coordinates are exported to CORSIM for the most realistic animation in CORSIM. If dummy external buffer nodes need to be created, they are now created starting at 999 (instead of 750) counting backwards, and detailed checks are made to make sure a dummy node number to be used is not already referenced elsewhere in the network. The default external link length for created buffer nodes is now 500 feet instead of 1,320 feet. Bend nodes are modeled using the same method as buffer nodes (side-street stop control with no side-street traffic). The cause of occasional invalid random number seeds has been tracked down and fixed, and better pseudo-random seed creation has been implemented. An inappropriate error which was issued when the Animate option of the Export dialog was selected has been suppressed.

PRESYNCHRO

In addition to the above for all PRE-processors, when dummy external nodes are created for the SYNCHRO network, a comprehensive check for prior use of the new node number is made before being used, and the default external link length for created buffer nodes is now 500 feet instead of 1,320 feet.

PRETSPPD

In addition to the above for all PRE-processors, when dummy external nodes are created for the TS/PP-DRAFT network, a comprehensive check for prior use of the new node number is made before being used, and the default external link length for created buffer nodes is now 500 feet instead of 1,320 feet.

PRENOSTOP

In addition to the above for all PRE-processors, dummy external nodes are omitted from the NOSTOP Export in order to minimize the number of intersections sent to NOSTOP (which has a maximum of 25 intersections), and links with bend nodes and/or unsignalized intersections are merged into a single link for the same reason. The new NOSTOP.exe executable file name is used instead of the previous WNOSTOP.exe. A missing field description in the Options-Setup dialog for the NOSTOP host location has been inserted.

TUTOR

The Programs option of TUTOR uses the new executable file names of the programs to launch a selected program.

TED

The TED text editor is fully integrated into each of the new Visual TEAPAC programs when TED is licensed.

TEAPAC Menu

The TEAPAC Menu has been updated to look for the new executable file names, but if not found it will look for the old file name so that old licenses or demos which have not been updated can still be run. For best compatibility among all the TEAPAC programs, it is highly recommended that all TEAPAC programs be upgraded to the same Version 7 status. The SIGNAL97 option in the TEAPAC Menu has been removed.

:TEAPAC Ver 6.01 23MAY05

Scroll down to 'Ver 6.00 08SEP04, Build 06 - 22SEP04' below for the major changes which were implemented for the original TEAPAC2004 release of this program.

Build 12 - 30SEP05

>Field Width Error Detection Modified for More Useful Performance.

A new error check was recently introduced to warn a user that too many characters for an input field had been entered and that the entry would be truncated. The aggressive response to this condition (ignoring the entry entirely) has been toned back, now accepting the truncated input with a similar warning. This reduces the potential for the need to re-type an entry which may be perfectly fine in its truncated form, or require only minor editing to correct instead of complete re-entry. The new error check has also been eliminated for any entries of the GROUPTYPES dialog, most of whose possible entry values can typically exceed the actual allocated input field width.

Another effect of the overly-aggressive error check was that certain drop-down list values in a number of dialog boxes had pre-programmed entries which exceeded the input field width, thus preventing them from executing properly. These included drop-down lists in the OUTPUT, CONDITIONS, GENERATION and PATHDISTRIBUTION dialogs. The field widths of all of these entries have been modified to accept the full drop-down list pre-programmed entries.

>Extra Warning Message Eliminated When Opening New Files.

If a user is warned about unsaved data or results values when a new file is about to be opened, with an option to first save the values, certain circumstances could cause the same message to be re-displayed a second time, regardless of the user response to the first message. This duplicate warning message has been eliminated.

>Debug Value Removed from Display for Text Search Function.

A spurious debug value was inadvertently left in the production version of the program, displaying each time a text string is searched for in any output window or edit window. The debug display has been removed.

>Key Files Are Now Valid for All Prior Versions of Program.

The key file processing logic has been enhanced to allow a given key file to be used not only for various builds and minor updates for the licensed version, but also for any version of the program prior to the licensed version. This minimizes the hassle of multiple key file management when multiple versions of a program are being used, for example, to maintain consistency in results throughout the course of a project which was begun with an older version of a given program that has been updated.

Build 11 - 22AUG05

>Optimized Timings Can be Imported in PRE-processors When Defined 'By-Movement'.

Optimized timings can now be Imported in all the TEAPAC PRE-processors when the timing entry styls is 'By-Movement'. This includes PRETRANSYT, PREPASSR, PRESYNCHRO, PRETSPPD and PRENOSTOP. Previously, this was not possible.

>Bug In Synchro Requires Reading LANES File Twice for Correct RTOR Values.

A bug has been identified in Synchro which requires that the LANES UTDF data file be read again after all other UTDF files have been read in order to make sure that the RTOR values are properly transferred from PRESYNCHRO into Synchro. A bug fix for this problem is pending for Synchro 6.

Build 10 - 04AUG05

>Minor Generic Enhancements and Fixes for TEAPAC2004 Ver 6.00 Release.

A number of minor enhancements and fixes have been made to the Ver 6.01 releases of TEAPAC2004 and are collectively included as Ver 6.01 Build 10. These are documented below and use heading lines that begin with T2004v6:. In addition, minor program-specific changes have been made, as summarized here and detailed in the program's own specific list of updates and changes. Ver 6.01 changes are free updates for Ver 6.00 licenses.

SIGNAL2000 -- the precision of default lane utilization factors used has been increased from two decimal places to 3 decimal places.

PRESYNCHRO and PRETSPPD -- right turn overlaps are now fully handled by the Import and Export functions.

WARRANTS and TURNS -- DFL site codes of up to nine characters can now be imported.

>T2004v6: Print Problem Resolved from Tabular View.

Difficulties experienced by some users attempting to print results when using the Tabular View have been resolved.

>T2004v6: Improved Phasing Display in Dialog Boxes.

The currently-selected signal phasing for an intersection which is displayed in some dialog boxes has been improved so that improperly-coded permitted left turns display differently than expected to indicate the error in coding.

Build 00 - 23MAY05

>Minor Generic Enhancements and Fixes for TEAPAC2004 Ver 6.00 Release.

A number of minor enhancements and fixes have been made to the Ver 6.00 releases of TEAPAC2004 and are collectively included as Ver 6.01 Build 00. These are documented below and use heading lines that begin with T2004v6:. In addition, minor program-specific changes have been made, as summarized here and detailed in the program's own specific list of updates and changes. Ver 6.01 changes are free updates for Ver 6.00 licenses.

NOSTOP and PRE-Processors -- the default scale for PLOTting a time-space diagram has been changed from 100 feet/line to 0, the new default of 0 being a code that instructs the program to determine a scale automatically which will include the entire time-space diagram on a single page.

NOSTOP -- the offset to the first main-street phase has been added to the right margin of the time-space diagram; input limits have been adjusted for DISTANCES and SPLITS to prevent errors when dividing by very small numbers; and dialogs and result reports have been modified to indicate that SPLITS are complete phase times, including both CLEARANCES and ALLREDS.

PRENOSTOP -- an error in the installed configuration file which prevented successful installation of PRENOSTOP anywhere but the default C:\TEAPAC folder has been corrected.

PRETRANSYT -- better card type 29 coding has been implemented regarding the determination of the opposed movements of a stop-controlled movement on the stem of a T-intersection, recognizing the likelihood of certain movements not existing due to the T structure of the intersection.

SITE -- an important note regarding cumulated computations and the new VOLADDITIONALS values has been added to the COMPUTE dialog help; and possible problems saving ACTUATIONS values with SITE were fixed.

>T2004v6: New Message Warns User That Calculated/Imported Values Have Not Been Saved.

A new message has been created which warns a user when calculated and/or imported values will be lost when the program is closed or File-New is used. This provides a check against inadvertently losing data results which could otherwise be saved in a file for future use or use by another program. The existence of unsaved calculated and/or imported values is indicated in the window caption with an asterisk (*) in the same fashion as changed user entry values. A similar message is now issued when File-Open or Reset [Parameters] is used when edited, calculated and/or imported values have not been saved.

>T2004v6: Edit Window Contents Can Be Printed, Including Line Numbers.

The contents of the TED Edit window, either within TED or the built-in edit window in any TEAPAC program, can now be printed using the normal print menu or toolbar buttons, including line numbers.

>T2004v6: LinkTo followed by Another LinkTo Performs Properly.

Multiple LinkTo operations can now be performed smoothly under all conditions without limitation. Previously it was observed that under certain conditions, one LinkTo followed by another LinkTo could cause certain problems successfully connecting to the next desired program.

>T2004v6: VOLADDITIONALS Values Now Allowed to be Negative.

The entry or computed values for VOLADDITIONALS is now allowed to have negative values, with a complete input range permitted from -9999 to 9999. This is primarily to afford the possibility of re-assignments of traffic to result in a net reduction of volume for individual movements, either by manual entry or computations from SITE. In the case of SITE, this also means that ROUNDing of results can create small negative VOLADDITIONALS in locations that receive little or no new traffic and where final volumes are rounded down (this is appropriate and to be expected).

>T2004v6: Global Entry of Additional Sequence Codes Now Includes All Extra Codes.

The entry of additional sequence codes for intersection 0 (to be assigned to all intersections) has been expanded so that all extra sequence codes will be assigned to all intersections, not just the first extra sequence code. This allows added flexibility when using this global entry feature for SEQUENCES.

>T2004v6: Better Graphics for Phasing Display and Bitmap Buttons.

The arrows used to represent phasing in various dialogs have been improved in quality and appearance, and if timings for phasings are defined by-movement instead of by-phase, the by-movement phasing diagrams are now shown in every relevant dialog. In addition, the pan and zoom button bitmaps within the View-Network display have been improved for better clarity.

>T2004v6: Option to Select Pages to Print; Page 0 for Current Page.

An option has been added to the Print-Setup dialog which allows the selection of specific pages to be printed instead of always printing all pages in the output window. Selection of page 0 will print only the current output page (the page which contains the insertion point cursor).

>T2004v6: View-Network Works Without Defined Network Distances.

Previously it was not possible to perform the View-Network function unless all NETWORK distances had been entered. This was due to the function's attempt to establish a scale factor between the network distances entered and the potentially arbitrary coordinate system used. Now, if distances are not entered, View-Network simply assumes the scale factor is 1.

>T2004v6: Warnings If Too Many Characters Entered or Number Too Large in an Input Field.

If a user enters more characters in a dialog's input field than the dialog expects or can process, a warning is now issued and the entire entry is ignored, rather than just ignoring the extra characters. This allows for better understanding by the user that the entry may not have been processed correctly. The F5 Refresh button should be used in all cases to see the current dialog values after the warning. On a similar note, if an entry has a numeric value too large for the intended internal variable, this condition is also noted with a message rather than allowing the possibility of a more catastrophic reaction by the program at a later point.

:TEAPAC Ver 6.00 08SEP04

Scroll down to 'Build 06 - 22SEP04' below for the major changes which were implemented for the original TEAPAC2004 release of this program.

Build 07 - 07DEC04

>Minor Generic Enhancements and Fixes for Initial TEAPAC2004 Release.

A number of minor enhancements and fixes have been made to the initial release of TEAPAC2004 (Version 6, Build 06) and are collectively included as Build 07. These are documented below and use heading lines that begin with T2004v6:. In addition, minor program-specific changes have been made, as summarized here and detailed in the program's own specific list of updates and changes. Build 07 changes are free updates for Build 06 licenses.

SIGNAL2000, SITE, WARRANTS, TURNS and PRE-Processors -- blank lines are now inserted between intersections and site generation data in TEAPAC2004 data files to aid in distinguishing the parts of the data file when being viewed as a text file.

SITE, WARRANTS and TURNS -- the saved values for ACTUATIONS (for use by signal operations programs such as SIGNAL2000) may have been corrupted in the initial TEAPAC2004 version of the program. This has been corrected. If legitimate ACTUATIONS values existed in any data file which was subsequently saved by this program, these values should be checked carefully for validity. If an attempt is made to read such corrupted values, error messages will be issued which should be ignored, then the values should be verified and/or corrected. Also, the representation of the Intersection entry in a Tabular View has been modified in its appearance so it is consistent with all other TEAPAC programs. The change includes representing the intersection number and description as a single entry field, as well as providing a button to 'Execute' the entry.

WARRANTS and TURNS -- IRD machine count data files with the .PRN file extension can now be Imported directly into TURNS and WARRANTS by specifying an Import file with a .PRN extension. This operates much like the Numetrics Import, where a Periods entry should already be in place before the Import, and several Imports to different movements can be accomplished, as needed. Multiple counts cannot be accumulated to a single movement (this is different than the Numetrics Import). Also, the parameter values which are normally entered in the special dialog which appears for TAS, Numetrics and IRD machine count Imports can now be entered at the end of a manual mode Import command. When this is done, the special dialog will display the manual mode entries so no further adjustment is required. Further, if an additional non-zero entry is made after these values in the manual mode, the special dialog will not be displayed at all. This feature allows the Import command to be included in a control file and thus run unattended.

WARRANTS -- + and - buttons have been added to the main window and all relevant dialogs as a convenient way of navigating among the various intersections of the Nodelist without the need to visit the Intersection dialog to select a new 'current' intersection.

PRESYNCHRO -- the dialog box labels for eastbound movements in the diagonal import assignment dialog (right side) have been corrected to properly represent the movements which the graphics in the dialog clearly depict. This is only a cosmetic change in the appearance of the dialog box, and does not affect any data entry values as long as the graphics of the dialog have guided the input process (most likely the case).

>T2004v6: Last Output Window Contents Saved in Text File Upon Program Closure.

The contents of the last Output Window display are now always saved in a temporary file (TMPxxx.OUT, where xxx is the program's abbreviated name) when a TEAPAC2004 program exits, thus leaving the last output produced in a text file for review and post-processing, if desired. The file is located in the folder which contains the authoring program (usually C:\TEAPAC) and is over-written the next time the same program exits. This feature also allows viewing of results created by a scripted control file which contains the Stop command, as well as multiple, linked control files which link to each other or are run from a batch command file. Also, a change has been made to make sure that all output generated by launching a control file from a command line is captured in the Output Window and/or the TMPxxx.OUT file. Lastly, if an Output Window is open when a Stop command is encountered in a control file, that Output Window is now always closed automatically.

>T2004v6: Automatic Closure of Save Message.

The message which is displayed when File-Save is used is now closed automatically in all cases after a brief display to confirm that the save has occurred as desired. Only Advanced file save messages are displayed until closed manually (unless the automatic closure checkbox is selected). Any save action directed from a control file is also closed automatically after a brief display in order to allow unattended operation.

>T2004v6: View-Network Shows Exiting External Legs.

The schematic network diagram created by the View-Network menu will now show external intersection legs for one-way street segments departing from an intersection.

>T2004v6: Longer Window Caption File Path Display.

The number of characters used to display the current file name(s), path and save status has been increased so that more of the file path is visible in the top caption line of the main window.

>T2004v6: Tabular View Caption Fix Prevents Corruption of Node# Display.

A problem in the caption display of the Tabular View window has been fixed so it no longer corrupts the display of the Current Node in the main window.

>T2004v6: File Functions Restored in TEAPAC Menu.

The 'Use this file:' function has been restored to the TEAPAC Menu so a file can be found by browsing, dragging to the Menu window, or double-clicking in Explorer. Then use of that file can be transferred to any TEAPAC program in the Menu. This function was inadvertantly disabled in the initial TEAPAC2004 release.

Build 06 - 22SEP04

>TEAPAC2004 (Version 6) Released After 2 Years in Development.

After 2 years in development, TEAPAC2004 (Version 6) has been released with a major enhancement to the generic user interface used by all programs, as well as major developments to individual programs. A summary of these enhancements follows for each TEAPAC program, followed by the details of the generic interface changes now found in all TEAPAC programs.

SIGNAL2000 and PRE-Processors -- completely seamless, one-click, one-file exchange of all input and results with each other, SITE, TURNS and WARRANTS, including calculations of HCM satflows, optimized timings, peak-period turn counts and estimated site traffic; new volume adjustment inputs to allow factoring volumes and adding additional volumes on a movement-by-movement basis; new sensitivity controls for global testing of factored volumes, additive volumes, factored satflows, minimums, clearances, etc.; complete implementation of the enhanced TEAPAC2004 (Ver 6) user interface, as described below.

PRETRANSYT -- in addition to above, direct support for TRANSYT-7F Release 10.

PRESYNCHRO -- in addition to above, automated graphical dialog for easier import of diagonal legs from Synchro/SimTraffic.

PRENOSTOP -- new program connecting NOSTOP with all of the other TEAPAC programs, including all of the features described above and the TEAPAC2004 user interface.

SITE -- increased network size as large as 500 intersections using arbitrary intersection numbers (not limited to 1..N); completely seamless, one-click, one-file exchange of all input and results with SIGNAL2000, TURNS, WARRANTS and all the PRE-processors, including capacity analysis of projected traffic, optimization of projected conditions, and peak-period turn counts as background traffic; new sensitivity controls for individual and/or global testing of inputs such as factored volumes; complete implementation of enhanced TEAPAC2004 (Ver 6) user interface, as described below.

TURNS and WARRANTS -- multi-intersection data management in one data file with up to 500 intersections per file; completely seamless, one-click, one-file exchange of all input and results with SIGNAL2000, SITE and all the PRE-processors, especially to deliver peak-period traffic volumes to all these programs as existing or background traffic conditions, as well as calculated peak hour factors and truck percentages; complete implementation of enhanced TEAPAC2004 (Ver 6) user interface, as described below.

NOSTOP -- support for the new PRENOSTOP program to connect NOSTOP with all of the other TEAPAC programs, including all of the features of the TEAPAC2004 user interface which apply.

TED -- ability to edit files of virtually unlimited size, as well as all the TEAPAC2004 (Ver 6) user interface developments which apply to the Edit window.

WTEAPAC Menu -- new File menu shows recent files; new Options menu allows program folder setup; new Help menu can list recent installed changes and check internet for updates; default support for VISSIM 4 and TRANSYT-7F Release 10; TEAPAC files which are double-clicked to be launched thru the TEAPAC Menu now open into the menu only without launching the program that created the file (since any file can now be used by any program, this old action is no longer appropriate).

>T2004v6: TEAPAC2004 Interface Enhancements Found In All Programs.

TEAPAC2004 (Ver 6) includes a multitude of enhancements which are part of the generic user interface found in all TEAPAC programs (some do not apply to NOSTOP, TED or TUTOR, for readily-apparent reasons). All of the generic enhancements are listed below with heading lines that begin with T2004v6:.

>T2004v6: One Common Data File Supports All TEAPAC Programs.

The most significant and obvious change made to each TEAPAC program in Version 6 is that all programs now share a single, common data file structure that contains all of the data entries used by all TEAPAC programs. This means that any TEAPAC program (except NOSTOP and TUTOR) can open any file from any other TEAPAC program, make changes to any of the data values it contains, and re-Save the file with complete retention of all data values for future use by any other TEAPAC program.

The first implication of this major fundamental change is that the concept of File-OpenShare of earlier TEAPAC programs is no longer needed since the sharing of TEAPAC files among TEAPAC programs is now fundamental and automatic. File-OpenShare has been re-named to File-OpenMerge/Share to better reflect its current function, to merge the content of multiple files, and can still be used to read and merge the content of files from older versions of SIGNAL97, SIGNAL2000 (Ver 1), SITE, TURNS and WARRANTS -- OpenMerge is automatic when reading these files. Also, the warning message when saving to a file created by one of these other programs has been removed, again because this function is now standard procedure and has no risk of loss of data.

The second implication of this change is that any values computed by one program and to be used by another (such as peak-period volumes from TURNS, HCM satflows from SIGNAL2000, optimized signal timings and phasings from SIGNAL2000, projected traffic from SITE, etc.) need only be saved into the data file with File-Save, then the next program launched with the same file using the LinkTo menu. A single click positions the user in the next program ready to do the analysis of that program.

Lastly, all programs (except NOSTOP and TUTOR) now have the ability to store all of this data for up to 500 intersections in a single file.

>T2004v6: LinkTo Menu In All TEAPAC Programs Includes All TEAPAC Programs.

All TEAPAC programs (except NOSTOP and TUTOR) now contain the LinkTo menu which now provides immediate access to all other TEAPAC programs with a single click which causes the current data file to be re-opened in that program.

>T2004v6: LinkTo Function Now Allows Direct Link to Host Programs.

A new function of the LinkTo menu has been added which allows direct linkage to the six host programs which are supported by the six TEAPAC preprocessors. These are PRETRANSYT for TRANSYT, PREPASSR for PASSER, PRENETSIM for CORSIM, PRESYNCHRO for Synchro/SimTraffic, PRETSPPD for TS-PP/Draft, and now PRENOSTOP for NOSTOP. Since all programs have access to the control directives for all the preprocessors, this means, for example, that a TRANSYT run can be made directly from SIGNAL2000 with a LinkTo-TRANSYT (assuming a licensed copy of PRETRANSYT is installed on the system).

>T2004v6: Global Input Option for Most Intersection Inputs.

A powerful new feature has been added to all TEAPAC programs that allows the value of a single data entry to be made to all intersections in the NODELIST (or the SUBSYSTEM, if one is defined). This is done when Intersection 0 is selected, and the user is first warned of the pending global entry action and followed by an audible beep when the global entry is made. The warning message can be omitted for future such actions, if desired.

Examples of uses for this new feature include the following: Enter a common cycle length or cycle range for SIGNAL2000 optimization of all signals; designate a full SIGNAL2000 phasing optimization for all signals; set the new volume adjustment factor or number of years for compounding a growth factor for all intersections for sensitivity analysis; enable or disable the new additional volumes entry for all intersections; designate a common peak hour factor for specific movements or all movements of all intersections; set the minimum or required clearance values for optimization at all signals; set the satflow adjustment factor for all signals to perform sensitivity analysis; etc. The possibilities of this new feature are virtually endless.

>T2004v6: View-Network Function Improved with Easier Pan & New Zoom.

The View-Network function has been added to all programs (except NOSTOP and TUTOR), and has been greatly improved in functionality regarding the ability to pan up/down and left/right, as well as new functions for zoom in/out and selecting a view area of the network connections and underlying bitmap with the mouse.

>T2004v6: Output/Edit Window Major Enhancements.

The Output and Edit Windows have been enhanced with menus and toolbar buttons which provide the ability to Find a user-entered text string, find the next output report and find the next page of results. A button also allows moving backwards thru the output to the previous output page. In the Edit Window, an additional Find & Replace function has also been provided. Also, the current line number of the cursor is displayed in the status line of the window, and the ^A function now performs the standard 'SelectAll' function instead of copying the entire window to the clipboard.

>T2004v6: Toolbar Button Provided for Intersection Selection.

A toolbar button has been provided in the main window next to the +/- buttons which provides direct access to the Intersection dialog to select the 'current' intersection, allowing quick access to this common function without the need to use the menus.

>T2004v6: Intersection/Type Description Listed in Dialog Caption.

If an intersection description has been provided for the current intersection (via the Intersection dialog), this description is displayed in the caption of any intersection data dialog in addition to the intersection number. For traffic impact studies with SITE, the same function is true for the current distribution type. These number and description displays are now also included in the caption of the Tabular View window.

>T2004v6: Check For Internet Update Function Provided.

A new function has been provided in the Help menu of every TEAPAC program that allows the user to have the program check the internet for any available downloadable updates. This function can be set to automatically check for updates every time the program is launched. If updates are found, this fact is displayed along with the status of the update (free or if a fee is involved and what that fee is), as well as a link to a complete description of what functionality changes the update includes, the ability to launch an email requesting a new key for a paid update or a quote for an upgrade. Options to view a complete price list online, to launch an email requesting technical support, and to go to the Strong Concepts main web page are also provided. This feature was partially implemented in the most recent downloads of several TEAPAC programs and accepted with great enthusiasm.

>T2004v6: INTERSECTION Dialog Includes Option to Renumber a Node and All Refs.

The INTERSECTION dialog now contains a feature to renumber any intersection in the NODELIST to any value not currently in the NODELIST. When selected, all references to the old node number anywhere else in the network are also updated, making renumbering a snap.

>T2004v6: Save Remembers Selected Intersection/Type for Subsequent Open.

When data files are saved, a directive is placed at the end of the file which remembers the 'current' intersection and current distribution type so that these positions can be reset when the file is subsequently re-opened by either the same program or any other TEAPAC program.

>T2004v6: Error Message Help Leaves Dialogs Open so Errant Entries Can Be Seen.

When Help for an error or warning message is displayed, the dialog entry which caused the error or warning is now left open so the entered values can be inspected in relation to the help advise given. Also, a note is provided in the message to use the Refresh button to see the dialog with the actual current values which are likely to not reflect the entry attempted (which caused the error or warning).

>T2004v6: Errors Contain Cancel Button to Abort File-Open or Control File.

When errors or warnings are issued as a result of reading a data file, a Cancel button is now provided which allows the user to abort continued attempts to read the file. This is now a convenient way to halt attempted processing of a file which is clearly not what was intended, or for power users, a way to kill a control file which has gone off the deep end.

>T2004v6: OUTPUT Dialog Contains Entries for All Programs.

The OUTPUT dialog is a common dialog name which has had different content for most TEAPAC programs. This conflict and impediment for combining all the TEAPAC data into a single file for TEAPAC2004 has been resolved by having a common OUTPUT dialog for all programs which contains the OUTPUT parameters for all TEAPAC programs. In the manual mode and control files, this involves the addition of a new parameter #1 which is the name of the program for which the following values apply, and thus all OUTPUT parameters for all programs are stored in the file and displayed in the dialog.

>T2004v6: Wording on Dialogs Used by Multiple Programs Improved.

The wording on dialogs which are used by multiple programs in TEAPAC2004 have been clarified so that it is more apparent what the relevance is to the current program in which the dialog is found.

>T2004v6: NODELIST Entry Protected from Change in Tabular View.

The only safe place to change the NODELIST after it has been entered is in the Normal View NODELIST dialog, so the NODELIST entry in the Tabular View has been greyed and protected from change to avoid unintended changes and possible disastrous results.

>T2004v6: Options-Setup Uses Browse for Folder, not Browse for File.

The Browse button in the Options-Setup dialog now produces a Browse-for-Folder dialog instead of the File-Open dialog so it is more clear what the function will return.

>T2004v6: Dialog Actions Re. ROUTEs with 9+ Nodes Fixed, Including Save.

Certain problems with ROUTES which contained more than 8 nodes have been fixed, including saving these route definitions.

>T2004v6: Recent File Menu Option Works Under All Windows Platforms.

Display of recently used files in the File menu has presented problems under certain Windows platforms, and thus an option has been provided to turn this display off so recent files are accessed only thru the File-RecentFiles dialog. This problem has been fixed so recent files can be displayed in the File menu on any Windows platform, and thus the default condition for this feature has been changed from No to Yes.

>T2004v6: Command-Line Control File Enhancements.

When a user has set a TEAPAC program to start in the Tabular View, ASK commands in command-line control files could not be used. This limitation has been eliminated so this feature can be used, if desired.

The output window for output generated by a command-line control file now appears in front of the main window so it is immediately visible without the need to click it to bring it to the front.

A new /x option has been added at the end of a command-line file name which instructs the program to open the command-line file as File #x (the default is File #1, as before). This allows the data file which a control file #2-5 opens to be designated as File #1 so that it is the file which will be open for subsequent File-Save operations from the File menu. Opening command-line control files as #2-5 instead of #1 is now the recommended practice.

>T2004v6: -X Entry for INTERSECTION Number Allowed As Positional Input.

The intersection number on an INTERSECTION command line or dialog is now allowed to be a negative number between -1 and -N where N is the number of intersections in the NODELIST. When this is the case, the intersection selected is the i-th node of the NODELIST when -i is used. The expected use of this feature is to allow REPEAT loops in control files to easily sequence through all the nodes of the NODELIST when the NDOELIST is not in numerical order and/or not a sequential list of nodes from 1 to N.

>T2004v6: TEAPAC Menu Enhancements.

A new File menu in the TEAPAC Menu shows recent files which have been used by the program; a new Options menu allows program folder setup for all of the third-party programs supported by the Menu; a new Help menu can list recently installed changes and check the internet for updates; default support for VISSIM 4 and TRANSYT-7F Release 10 is provided.

TEAPAC files which are double-clicked to be launched thru the TEAPAC Menu now open into the menu only without launching the program that created the file (since any file can now be used by any program, this old action is no longer appropriate).

>T2004v6: Printable On-screen Manuals Available as PDF Downloads.

The full documentation for each TEAPAC program has always been directly available as the on-screen manual which also serves as the context-sensitive Help document. Options for obtaining printed/bound copies of this document have also been available at an additional cost. Now, in addition, this document is available as a downloadable PDF file which provides the ability to print a copy locally, as well as search the entire document for user-defined strings.

:TEAPAC Ver 5.12 22NOV03

Build 16 - 16JUL04

>SIGNAL2000 More Flexibility Added for Lost Time Calculation in Compound LT.

SIGNAL2000 has been enhanced to provide the ability to have different lost time values calculated for the protected and permitted portions of compound left turns. In prior versions, a single lost time value was calculated for each movement of an intersection. Now, if Yellow+AllRed clearance times are different for the protected and permitted phases of a protected-permitted or permitted-protected left turn, the computed lost times for these two conditions will be different, better reflecting the different behaviors these phases might experience.

>SIGNAL2000 & PREPROCESSORS Fix NODELIST & SUBSYSTEM Dialogs w/ >100 Nodes.

A problem has been fixed which could cause difficulties displaying a node list with more than 100 nodes in the NODELIST and SUBSYSTEM dialogs of the 500-node version of the program.

>Automatic Check for Updates Added When Connected to Internet.

A new feature has been added which allows an automatic check for updates via the internet any time the program is started when an internet connection is present. The automatic check can be disabled from the Help menu using the CheckForUpdates option. The same menu selectiion can be used to manually check for updates, to review details about any available updates, to download updates, to see update prices (if they are not free), to request a quote for updates and to order certain updates.

>Accelerator Key Definitions Added to Tooltip Help for Dialog Buttons.

Tooltip help strings for certain dialog box buttons have been updated to include the accelerator keys which can be used in lieu of the buttons.

Build 14 - 29MAR04

>Installation Setup Modified for Proper Creation of Shortcuts.

A change has been made to the configuration of the new MSI installation setup now used by most TEAPAC programs. Now when shortcuts are created in the start menu or the desktop during installation, they are configured properly with the installation folder set as the 'Start In' folder (Working Directory) for the shortcut. In recent TEAPAC releases which use the new MSI installation system, this configuration option was not selected, resulting in a possible problem when running the program in Exporting to HCS and locating the Help file (on-screen manual, Help-Contents menu, Help buttons and F1 key) and/or the Recent Changes file (Help-RecentChanges menu).

Build 12 - 03MAR04

>All Programs Receive Minor Ver 5.12 Interface Updates.

All TEAPAC programs using the Ver 5.1x TEAPAC Interface have been further refined with additional features to aid in the analysis process. These include: 1) saving the current intersection in the data file so that when the file is re-opened, the same current intersection is re-established, 2) providing the ability to scale a bitmap background for a single intersection analysis by right-clicking on a point 100 feet from the intersection, and 3) providing a Clear button on the Subsytem and Route dialogs so that the lists displayed can be removed with a single click.

The TEAPAC Menu System now runs SYNCHRO 6 by default, and shows ITC's new name (PTV America) for VISSIM. A summary of the program-specific changes is provided below. Refer to the detailed Recent Change notes for each program for more details. These are all free update downloads from www.StrongConcepts.com for current licenses.

>SIGNAL2000 Important Update for More Reliable Capacity Analysis Calculations.

The new method under use in DESIGN for optimization regarding setting certain protected-permitted left turn flags has been implemented for more reliable and consistent determination of these flags under capacity-analysis-only conditions. Also, obscure but possible cases which could cause abnormal program termination are now detected and reported in an orderly way.

>All Preprocessors Improve Selection of Default System Cycle & Coordinate Scale.

The system cycle length used when the MASTERNODE is not used (or not in the current SUBSYSTEM) is now the first node of the SUBSYSTEM rather than the first node in the NODELIST. If the user uses a coordinate system different than ground coordinates, an imporved method is used to establish the scale that relates these two coordinate systems, with less bias from outliers or coordinate input errors. Also, a background bitmap in the View-Network display can be scaled for use by other programs in a single-intersection analysis by right-clicking a point 100 feet from the center of the intersection.

>PRETRANSYT Accommodates Certain TRANSYT Input Limitations.

PRETRANSYT now makes sure that a calculated queue storage capacity which exceeds the TRANSYT limit of 200 vehicles does not place a capacity higher than 200 in this field of the input data file. Also, RTOR is not coded for links which do not have any non-permitted opposing links in the TRANSYT network model, and empty record types 02 and 70 have been eliminated from the input data file.

>PRESYNCHRO Improvements to Import and Export Functions.

Exported timings are now checked and adjusted to make sure that the exported times in tenths of seconds add up exactly to the cycle length. The way T-intersections and 1-way streets are exported has been improved, particularly in relation to how shared and/or 'not-opposed' left turns are handled for both phasing definition and timings.

Lost time import and export have both been significantly enhanced to provide greater consistency with the Highway Capacity Manual definitions of lost time and related parameters, and as applied in the SIGNAL2000 program. Also, entry of intersection coordinates is now verified before exporting since they are an intrinsic requirement of SYNCHRO for its displays and certain calculations.

>PRETSPPD Improvements to Export Function.

Most of the PRESYNCHRO improvements above also apply to PRETSPPD. In addition, several new options available in TSPPD Ver 6.0.0.13 have been implemented for easier readability and comparison to 'traditional' bandwidth representations of flow.

>PREPASSR Import Adjustment.

In relation to the adjustment of the default system cycle described above, the affect that this change has on importing PASSER II-02 results has been accommodated.

>PRENOSTOP (and NOSTOP) Enhancements.

As PRENOSTOP draws closer to its first official release later this year, further enhancements have been made to its PreRelease version (PreRelease 06). Most notably, the Import function has been implemented so that optimized offsets and cycles can be imported from NOSTOP back into PRENOSTOP for further review and/or transfer to other TEAPAC programs such as SIGNAL2000, PRETRANSYT, PRENETSIM, etc. In addition, minor improvements to the Export function have been made to accommodate certain unexpected conditions. The option to run NOSTOP without viewing any of the NOSTOP run directly has also been implemented. Use of the new Import function requires a new PreRelease version of NOSTOP in order to function properly (contact Strong Concepts for availability).

>WARRANTS and TURNS Minor Import Display Fix.

A display problem in the CSV Numetrics import dialog has been fixed so that it is clear that the default movement is 0 and must be entered with a value between 1 and 12.

Build 10 - 31DEC03

>All Programs Use Microsoft Installer (MSI) Ver 2.

The Microsoft Installer (MSI) Version 2 is now used by all TEAPAC programs for the installation process, including the installation of the complete package from a single file.

>WARRANTS and TURNS Updated for 2003 MUTCD and a Few Fixes.

WARRANTS and TURNS have been updated to include the 2003 MUTCD methodology as the default method, and a few fixes have been made to the 2000 MUTCD warrant analysis based on recent FHWA rulings. Also, support for importing Numetrics automatic counter data files has been added.

>PRESYNCHRO Supports Ver 6 of SYNCHRO/SIMTRAFFIC, Plus a Few Fixes.

PRESYNCHRO has been modified so it supports Version 6 of Synchro and SimTraffic directly. Export has also been fixed for input timings given in seconds/second and for 1-way linnks leaving the network (SimTraffic only). A few new features have been added for TEAPAC Interface Ver 5.12.

>PRETRANSYT Updated to Accommodate Error in TRANSYT Documentation.

PRETRANSYT has been modified so that offset-only optimizations are performed correctly, in contrast to the method described in the TRANSYT documentation. A few new features have been added for TEAPAC Interface Ver 5.12.

>PRETSPPD Fixes Seconds/second Export.

Export has been fixed for input timings given in seconds/second and a few new features have been added for TEAPAC Interface Ver 5.12.

>PREPASSR Fixes Import of PASSER Results.

PREPASSR has been adjusted so that when optimized timings from PASSER are imported (in seconds), they will be treated properly if the original input timings were given in seconds/second. A few new features have also been added for TEAPAC Interface Ver 5.12.

>SIGNAL2000 and PRENETSIM Minor Updates.

A few new features have been added for TEAPAC Interface Ver 5.12.

:TEAPAC Ver 5.11 02FEB03

Build 54 - 05JUN03

>SIGNAL2000 Lost Time Adjustment.

Lost times in SIGNAL2000 are now re-calculated before each capacity analysis which is performed as part of a DESIGN N analysis.

>PRESYNCHRO Debug Trace Statements Removed.

Unnecessary debug trace statements in PRESYNCHRO were inadvertantly left in Build 52 and have been removed.

Build 52 - 04JUN03

>Updated PRESYNCHRO for Expanded and Improved Import and Export Functions.

Many enhancements and adjustments have been made to the new PRESYNCHRO program to improve the quality of both the Import and Export functions from and to SYNCHRO/SIMTRAFFIC.

>SIGNAL2000 and All TEAPAC Preprocessors Use New Logic for Converting Timings.

A new ccordination between YELLOWTIMES ByMovement and REQCLEARANCES improves the way signal timings are converted between the ByPhase and ByMovement styles of input and display.

>PREPASSR Export to PASSER II-02 Handles Data Files in Folders with Spaces Better.

A change in PREPASSR allows data files to be sent to PASSER II-02 by the EXPORT AUTO function when these data files reside in folders which have spaces in their path names.

>All TEAPAC Preprocessors Ignore Dummy Nodes When Producing TIMINGS Report.

Each of the TEAPAC preprocessors PRETRANSYT, PREPASSR, PRENETSIM, PRETSPPD and PRESYNCHRO now ignore dummy nodes (as well as unsignalized intersections) when producing the TIMINGS report.

Build 50 - 08MAY03

>New TEAPAC Programs Added to Support TS/PP-Draft and Synchro/SimTraffic.

Two new TEAPAC programs have been added to the TEAPAC system - PRETSPPD and PRESYNCHRO. These programs interface all other TEAPAC programs to the TS/PP-Draft and Synchro/SimTraffic programs. Buttons for each of these TEAPAC and third-party programs have been added to the WinTEAPAC Menu System.

>New Seamless Integration Among TEAPAC Programs.

PREPASSR, PRETRANSYT and PRENETSIM have been modified to provide the seamless integration introduced in SIGNAL2000 Ver 2. This feature allows these programs to quickly transfer control and data between themselves, the new PRETSPPD and PRESYNCHRO programs, and SIGNAL2000 with a single LinkTo menu click. Other changes were made for compatibility with SIGNAL2000 Ver 2 including the option to enter and/or view signal timings in a NEMA-style, ring-based format.

>Enhanced Third-Party software Support.

PREPASSR has been upgraded for direct support of the new PASSER II-02 program. PRETRANSYT has been upgraded for direct support of the latest TRANSYT-7F Release 9.7. PRENETSIM has been upgraded for direct support of new features offered by TSIS/CORSIM Version 5.1.

>Minor Update to SIGNAL2000 for Consistency with Changes Above.

SIGNAL2000 has been updated to incorporate the TEAPAC Interface Ver 5.11 which appears in all the new programs and upgrades described above. These include adding the new programs to its LinkTo menu, improved ability to read old-style formatted data files from PREPASSR, PRETRANSYT and PRENETSIM, the display of 'PedPhase' in phasing diagrams which include exclusive pedestrian phases, and the ability to automatically skip dummy nodes imported from a Synchro data file via PRESYNCHRO.

:TEAPAC Ver 5.10 30NOV02

Build 12 - 06DEC02

>Minor Changes to Finetune the Initial Release of SIGNAL2000 Ver 2 and WinTEAPAC Ver 5.10.

Minor changes to the initial release of SIGNAL2000 Version 2 to improve View-Network on low resolution screens and negative overlap optimization. Change to default installation folder for locating next release of VISSIM (3.70) in WinTEAPAC menu.

Build 10 - 03DEC02

>SIGNAL2000 Version 2.

Build 16 - 14JUL02

>New Version of SIGNAL2000 and SITE.

This release of the TEAPAC Suite includes new versions of SIGNAL2000 and SITE. Primarily, these programs incorporate a new options for compatibility with the same options added to PREPASSR, PRETRANSYT and PRENETSIM earlier this year. See the RecentChanges Update Messages of each of these programs for more specifics about these and other changes implemented.

>New Builds of All TEAPAC Programs Released Using Ver 5.02 Interface Updates.

All TEAPAC programs have been released as Build 16, incorporating the latest TEAPAC2000 Interface Ver 5.02 Build 16. Some of these programs have other minor changes implemented concurrently, others have no change except the build number. See the RecentChanges Update Messages of each of these programs for more specifics about these and other changes implemented.

Build 02 - 25MAY02

>New Version of WARRANTS and TURNS.

This release of the TEAPAC Suite includes new versions of WARRANTS and TURNS. Primarily, these programs incorporate a new warrant analysis for multi-way stops following the methods of the 2000 MUTCD. See the RecentChanges Update Messages of each of these programs for more specifics about these and other changes implemented.

Build 00 - 25APR02

>New Versions of PREPASSR, PRETRANSYT and PRENETSIM.

This release of the TEAPAC Suite includes new versions of PREPASSR, PRETRANSYT and PRENETSIM. Primarily, these programs implement a large number of enhanced modeling capabilities such as sign control, right-turn-on-red, free-flow lanes, etc. to take advantage of these same capabilities in TRANSYT and CORSIM. See the RecentChanges Update Messages of each of these programs for more specifics about these and other changes implemented.

>TRANSYT Button Runs T7F9.exe.

The TRANSYT button in the TEAPAC menu now runs the T7F9.exe program as the default TRANSYT program (instead of the McT7F.exe program).

>New Features for Host Definition and Launching.

The WTEAPAC.CFG file now allows the name of the Host executable file to be added at the end of the Host path, in the event that this executable name is different than that used by default. This is most likely when using an older version of a host program (such as TRANSYT or CORSIM). The .CFG file can be changed with any t4ext editor such as NotePad.

>TEAPAC2000 Version 5.02 Generic Interface Fine-Tuning.

In the first release of the TEAPAC2000 Ver 5 Interface, users may have experienced difficulty using the Advanced Datafiles LOAD and SAVE functions from the Tabular View. These functions have been updated to work properly from the Tabular View.

Error messages generated from the Manual Mode, data files or control files will list the specific line of input which generated the error, with the offending item highlighted in red. If the information came from a file, the file number and line number of the error is also listed.

Shortcut keys have been added to the File-RecentFiles and File-Save dialogs for more expediant keyboard manipulation.

Certain warning and error messages shouldn't be closed automatically by the new AutoClose option if these messages expect or require user response. The AutoClose option is now ignored for these cases.

The Help-Messages menu item has been changed to Help-RecentChanges to better reflect its purpose.

The Help-About menu item now shows the specific program name.

The default size of the Help window has been increased in size vertically to better display the contents of the complete, on-screen manual and context-sensitive help topics.

:TEAPAC Ver 5.01 02FEB02 Build 00

>New Version of SIGNAL2000 and NOSTOP.

This release of the TEAPAC Suite includes new versions of SIGNAL2000 and NOSTOP. Primarily, SIGNAL2000 included changes to the HCM queue model approved by the HCM Capacity Committee in January, 2002; and NOSTOP included minor adjustments to improve the use of the new Tabular View. See the RecentChanges Update Messages of each of these programs for more specifics about these and other changes implemented.

:TEAPAC Ver 5.00 25SEP01 Build 10

>TEAPAC2000 User Interface Version 5 Implemented.

WARRANTS Ver 2.00 25SEP01 Build 10

>2000 MUTCD Warrant Analysis Implemented.

The 2000 MUTCD method for performing a Traffic Signal Warrant Analysis has been implemented in the WARRANTS program. The inputs required for the analysis are the same as the previous 1988 method. Note that the 2000 method now requires that the un-disrupted progression condition be met for any of the warrants to be satisfied. With this in mind, the sample problem data in the WARRANTS.FOR sample data file has been modified to include this condition, as well as measured stop sign delay and accident history, as a more realistic example.

A new parameter has been added to the WARRANTS command which describes which version of the warrant analysis is desired. Selecting 2000 (the default) produces a 2000 MUTCD signal warrant analysis, while selecting 1988 produces a signal warrant analysis using the 1988 method as produced by earlier versions of WARRANTS.

>Machine Counts Using TAS File Format Can Be Imported.

WARRANTS is now able to import electronic machine (tube) count files which use the TAS file format. This includes Jamar and TimeMark electronic traffic counters. This new feature allows machine counts to be easily input into WARRANTS for the purposes of a traffic signal warrant analysis. Multiple machine counts can be combined to include the counts for all approaches of the intersection, and multi-channel (multi-tube) counts can be processed by selecting which channel to use, or the sum of the channels, or the difference of the channels. A specific day of a multi-day count can also be selected, and the count can be directed to any of the twelve movements in the program.

TURNS Ver 3.50 25SEP01 Build 10

>2000 MUTCD Warrant Analysis Implemented.

The 2000 MUTCD method for performing a Traffic Signal Warrant Analysis has been implemented in the Usage Level 2 option of the TURNS program. The inputs required for the analysis are the same as the previous 1988 method. Note that the 2000 method now requires that the un-disrupted progression condition be met for any of the warrants to be satisfied. With this in mind, the sample problem data in the TURNS.FOR sample data file has been modified to include this condition, as well as measured stop sign delay and accident history, as a more realistic example.

A new parameter has been added to the WARRANTS command which describes which version of the warrant analysis is desired. Selecting 2000 (the default) produces a 2000 MUTCD signal warrant analysis, while selecting 1988 produces a signal warrant analysis using the 1988 method as produced by earlier versions of TURNS.

>Machine Counts Using TAS File Format Can Be Imported.

TURNS is now able to import electronic machine (tube) count files which use the TAS file format. This includes Jamar and TimeMark electronic traffic counters. This new feature allows machine counts to be easily input into TURNS for the purposes of a traffic signal warrant analysis. Multiple machine counts can be combined to include the counts for all approaches of the intersection, and multi-channel (multi-tube) counts can be processed by selecting which channel to use, or the sum of the channels, or the difference of the channels. A specific day of a multi-day count can also be selected, and the count can be directed to any of the twelve movements in the program.

PRETRANSYT Ver 2.70 25SEP01 Build 10

>Direct Support for TRANSYT-7F Release 9.

PRETRANSYT has been updated so that it directly supports the new Release 9 of TRANSYT-7F. This includes the new IMPORT format which is now recognized by PRETRANSYT, as well as the new default installation folder used by Release 9.

The default OUTPUT format for EXPORT from PRETRANSYT is now 7F9. Note that if data files saved with earlier versions of PRETRANSYT are being used with Release 9, the OUTPUT value in the file will over-ride the 7F9 default and needs to be changed to 7F9 prior to using EXPORT.

>Enhanced Dialog Buttons to Navigate Through Intersection Data.

New buttons have been added to each dialog which contains intersection data which makes it easy to move through the NODELIST of intersections when viewing that dialog's data. Pressing the '+' button in the dialog will change the intersection being viewed to the next one in the NODELIST, while pressing the '-' button will change to the previous intersection in the NODELIST.

PRENETSIM Ver 1.30 25SEP01 Build 10

>Direct Support for TSIS 5.

PRENETSIM has been updated so that it directly supports the newest version of CORSIM, TSIS 5. This includes the new executable name used by TSIS 5, as well as the new default installation folder used by TSIS 5.

>Enhanced Dialog Buttons to Navigate Through Intersection Data.

New buttons have been added to each dialog which contains intersection data which makes it easy to move through the NODELIST of intersections when viewing that dialog's data. Pressing the '+' button in the dialog will change the intersection being viewed to the next one in the NODELIST, while pressing the '-' button will change to the previous intersection in the NODELIST.

PREPASSR Ver 1.60 25SEP01 Build 10

>Enhanced Dialog Buttons to Navigate Through Intersection Data.

New buttons have been added to each dialog which contains intersection data which makes it easy to move through the NODELIST of intersections when viewing that dialog's data. Pressing the '+' button in the dialog will change the intersection being viewed to the next one in the NODELIST, while pressing the '-' button will change to the previous intersection in the NODELIST.

>IMPORT Enhanced.

IMPORT has been enhanced so that only a single set of PASSER data is imported, rather than the two sets which have been imported in the past. The two sets resulted from the way that the results file from PASSER is structured. IMPORT now recognizes this format and halts the import when a single complete set of import data has been imported. No change in the imported data results from this change, merely a less confusing and less redundant IMPORT report.

SITE Ver 4.10 25SEP01 Build 10

>Enhanced Dialog Buttons to Navigate Through Intersection and Type Data.

New buttons have been added to each dialog which contains either intersection data or distribution type data. These buttons make it easy to move through the intersections and types when viewing that dialog's data. Pressing the '+' button in the dialog will increase the intersection or type number being viewed by one, while pressing the '-' button will decrease to the previous intersection or type.

NOSTOP Ver 4.40 25SEP01 Build 10

No other changes have been made to NOSTOP other than implementing the new WinTEAPAC2000 Ver 5 Interface.

SIGNAL2000 Ver 1.10 25SEP01 Build 10

No other changes have been made to SIGNAL2000 other than implementing the new WinTEAPAC2000 Ver 5 Interface.

TED Ver 3.70 25SEP01 Build 10

No other changes have been made to TED other than implementing the new WinTEAPAC2000 Ver 5 Interface.

TUTOR Ver 5.00 25SEP01 Build 10

No other changes have been made to TUTOR other than implementing the new WinTEAPAC2000 Ver 5 Interface.

:TEAPAC Ver 4.01 15JAN00

>Changes to Standard TEAPAC2000 Interface, Ver 4.01.

All TEAPAC programs which have Windows versions use the new TEAPAC2000 Interface which was introduced in November, 1999. The following changes have been made to this interface to further enhance its effectiveness:

>Spaces Allowed in Folder Names for Data Files.

Folders which contain data files may now contain spaces in the folder name. Data files themselves are still limited to 11 characters including the extension and may not have embedded spaces (for continued compatibility with supported DOS products), but the restriction on path names (folders) has been removed.

>File Name Can Be Inserted in Title Lines.

The name of the current open file can be inserted anywhere in a title line (PROJECT, DESCRIPTION or NOTE entry) by placing %F at the desired location of the title line. The file name can be placed at a specific column location in a title line by using the +XX form of a title entry (see Help for any of the title commands).

>Bigger Output Window for Higher Resolution Displays.

Output windows containing program results which are displayed at resolutions of 1024x768 or higher now use a larger window so that more results can be displayed and less scrolling is required to observe all of the results.

>Additional Help and Shortcut Features Added.

Several new help features have been added. One of these is a new Help button on the toolbar for direct access to the on-line manual. Help notes in the status line at the bottom of the window for each of the menu items in the File menu have also been added. The File-Close menu item in the main window now uses a shortcut of 'C' instead of 'L' for consistency with other programs, and the File-Exit menu item in the Results window has been changed to File-CloseResults to avoid confusion with the File-Exit menu item of the main window. Lastly, the last used file name is retained in the File-Open and File-SaveAs dialogs, even when a previous dialog was cancelled.

>New Warning Messages.

A new warning message has been generated to warn users if unsaved data values are about to be reset to default values by the File-New menu item. A new message also warns if the installed folder has spaces in its name, which will cause problems in certain operations like printing.

>Potential Problem Running Under Windows NT Eliminated.

In the initial release of the TEAPAC 2000 interface (07NOV99), a technique for dynamic menu building was used which had a conflict with certain service packs and memory configurations of Windows NT. To avoid this potential problem on any given machine, the dynamic menu building has been removed and replaced with a method that will work on all configurations of Windows NT.

HCS2HCS

>Problem Converting Non-zero Grades Solved.

A problem converting approach grade entries has been discovered and resolved in this version of HCS2HCS. The problem only manifested itself when grade values other than zero were encountered in the HCS-2 data file. These non-zero grades would be converted improperly and wrong grade values may have been placed in the HCS-3 file. In some cases, data files with grade values of zero could have caused the Win32 versions of HCS2HCS to produce an HCS-3 data file which prevented final delay and level of service calculations to be produced, but in no case would wrong answers be produced when grade values of zero were the only values being converted.

NOSTOP

>Minor Adjustments for Added Clarity.

The allowed input range for the ADJUST command has been changed from 0.000..9.999 to 0.01..9.99. This avoids the possibility of entering a 0.00 value which causes a crash, as well as a slightly misleading upper range display value of 10.00 in the corresponding error-check message. The wording of the DISTANCES dialog has been modified slightly to remove the word 'average' which may confuse the intended input value.

PRENETSIM

>New CORSIM Ver 4.32 Unpublished Rules for Channelizations.

CORSIM Ver 4.32 processes lane channelizations differently than earlier versions of NETSIM and CORSIM, leading to erroneous lane usage by CORSIM 4.32 if the unrestricted channelization code is used. This is an unpublished change in the processing rules of CORSIM. This means that CORSIM data files which ran fine under previous versions of CORSIM will no longer produce valid results under 4.32, and there will be no message or warning to this effect. The only place it can be observed is in the animation where users will see vehicles turning from incorrect lanes.

Ver 1.24 of PRENETSIM follows the new rules of CORSIM 4.32, and the method implemented will work for older versions of CORSIM as well. Since up until now PRENETSIM has used the unrestricted channelization code, this means files exported from prior versions of PRENETSIM will not create valid CORSIM files for Ver 4.32.

Another unpublished change in CORSIM Ver 4.32 is the need for the project file to have a lower case .tcf extension. This was not required previously and prior versions of PRENETSIM used uppercase .TCF. As a result, prior versions of PRENETSIM will not launch these project file correctly (the TSIS screen will display briefly, then control will return to PRENETSIM with no further action by CORSIM). Ver 1.24 of PRENETSIM addresses this problem.

>Other Minor Changes to Improve Performance.

It has been found that TRAFVU objects to certain information found beyond card column 72 in Record Type 1, even when this information is processed without error by CORSIM. This error could occur when Exporting data from PRENETSIM which includes a long NOTE entry. In order to avoid this problem, the generation of the Record Type 1 has been modified to make sure this area of the record remains empty by shortening the amount of title information from PROJECT, DESCRIPTION and NOTE which is used to create Record Type 1. This is accomplished by using only the first 22 characters of each of these entries to create Record Type 1.

>Minor Change in NETSIM Export Choices.

Prior versions of PRENETSIM allowed exporting to different versions of CORSIM's predecessor (NETSIM) using the keyword entries of 4.2 and 5.0 on the OUTPUT command. These have been changed to 4.2_NETSIM & 5.0_NETSIM to prevent any confusion with an earlier version of CORSIM also called 4.2, as well as a pending version of CORSIM which will be called 5.0. No change in the Export process occured with this keyword change.

>Intersection Descriptions Displayed in TIMINGS Output.

Signal timing outputs produced by the TIMINGS command now display the intersection description in addition to the intersection number, if such a description has been provided.

PREPASSR

>Intersection Descriptions Displayed in TIMINGS Output.

Signal timing outputs produced by the TIMINGS command now display the intersection description in addition to the intersection number, if such a description has been provided.

PRETRANSYT

>New Support for Windows Version of TRANSYT-7F (Release 8.2).

PRETRANSYT now supports the Export function for all of the new calling sequences, program names and installation changes for the new Windows version of TRANSYT-7F (Release 8.2). PRETRANSYT maintains continued support for the DOS version of Release 8 (Release 8.1), as well as previous versions of TRANSYT-7F.

>Intersection Descriptions Displayed in TIMINGS Output.

Signal timing outputs produced by the TIMINGS command now display the intersection description in addition to the intersection number, if such a description has been provided.

SIGNAL97

>Export to HCS-3 (Signals) Fully Supported.

SIGNAL97 now supports the Export function for all of the new data file formats, calling sequences, program names and installation changes for the new Windows version of HCS-3 (Signals Patch b and beyond). SIGNAL97 maintains continued support for the previous DOS version of HCS Signals (Ver 1 and 2) through use of the data file extensions for those versions, if needed. In the Export to HCS-2, the lane utilizations export has been corrected to use the inverted value from those input into SIGNAL97.

>New Input Values Displayed in Data Summary and Results.

Input values which are new for the 1997 HCM methodology in comparison to the SIGNAL94 inputs are now listed in the data summary produced by the View-Summary menu item or the SUMMARISE command. These include the inputs for STARTUPLOST, ENDGAIN and UPSTREAMVC. If unit extensions are input for ACTUATIONS entries, these values are now displayed properly. Also, the duration of the analysis period used in the analysis is displayed in the Level of Service Worksheet, and a few additional values for the protected-permitted left turn adjustment factor worksheet are zeroed out for Case 6 analyses so they all display as zero.

>Zero Overlap Time Allowed for Sequence 8 Analyses.

A sequence code 8 phasing (Lead-Lag) should permit zero time being allocated to the overlap phase as long as the other phases have non-zero time, since no vehicle sees this phase by itself. However, the initial release if SIGNAL97 objected to such timings unless they came directly from DESIGN via the DESIGN 1 entry. This condition has been fixed so that no objection is made to zero overlap time by the ANALYZE function, regardless of the source of the timings.

TURNS

>Improved Wording for Progression Condition.

The wording describing the input progression condition used for a warrant analysis has been modified to more closely match that which appears in the MUTCD. Previously, the expressions 'good progression (no/yes)' and 'conducive to progressive traffic flow (no/yes)' were used, but these suggested that a signal must in fact promote progression to be warranted, which is not the intent of the MUTCD. The intent of the MUTCD is that a signal should not be disruptive to an existing progression if such a progression exists. In response to this situation, the phrase 'not disrupt progression (no/yes)' is now used. This fine point is especially important for an isolated signal location or a location where a progression does not exist. Although the double-negative now used in the input phrase is also potentially confusing, it mimics the language used in the MUTCD, and also allows all of the default CONDITION inputs to be 'NO' so that a 'YES' entry always means that a required condition has been met. This change has been made in all locations of the program, including the input dialog and output reports which document that input condition.
