SCENARIO has been superseded by and incorporated into the new TEAPAC Complete product which is described in detail at the main page of  Upgrades from SCENARIO to TEAPAC Complete are available.  Contact Strong Concepts for details.

:SCENARIO Ver 1.81 27MAY08

Build 11 - 27MAY08

>Include SCENARIO_000.tpc in distribution for CreateFromTemplate.

The SCENARIO_000.tpc file which is used by the CreateFromTemplate process was missing from some distribution packages which included the SCENARIO program. This file is now included in all distribution packages, and the corresponding old-format SCENARIO_000.for file has been removed.

>Look for SCENARIO_000.tpc in installed folder, not in data file folder.

The prior requirement that the SCENARIO_000 file (for CreateFromTemplate) be located in the same folder as the user's data files has been eliminated. The file is now always used from the installed folder where it is placed by the setup installation process.

>NOTE shows 'Issue X Not Selected' when case selection does not select an Issue.

When a scenario case is selected from a file using the File-GetScenarioCase menu, the various Conditions which are selected are described in the NOTE entry which is displayed on-screen and in each output report. When a Condition for a specific Issue is not selected, this 'unselected' status is now included in the NOTE so that it is apparent that there may be certain data that has not been populated by the GetScenarioCase process.

>File-SaveAs to an existing file name with Scenario conditions doesn't hang.

In prior versions, if File-SaveAs was used to save data using a file name that already existed with scenario condition files, the potential for a hung system occurred in the program's attempt to reconcile the conflicts between the condition files of the old file and the new file. This potential has been rectified.

>Generic changes made to all Ver 7.81 TEAPAC programs.

Allow negative percentage on ASSIGNMENT for Passbys and Diverted trips.
Use Shift while dragging mouse to define development area on network display.
Dialogs identify need for consistency between Yellowtimes & ReqClearances.
Display dummy node dot and node number if it is current node or in Subsystem.
Note in CrdSysMgmt dialog that NewLinkDist button assumes coords are in feet.
Able to save from OpenIntoEdit if it was first file opened into program.
NOTE shows 'Issue X Not Selected' when case selection does not select an Issue.
File-OpenMerge does not allow existing Network data to be overwritten by zeros.
File-SaveAs to an existing file name with Scenario conditions doesn't hang.
File-SaveAs shows file type of current file & better file type descriptions.

:SCENARIO Ver 1.80 25APR07

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 the program. The Forum can also be accessed directly using any internet browser at

:SCENARIO Ver 1.71 08SEP06

Build 07 - 25JAN07

>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.

>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.
