|WinSIGNAL94 Is Now Shipping|
Last fall, the first public viewing of the Windows
version of SIGNAL94 at the Annual ITE Meeting in Minneapolis
was met with rave reviews. After an extensive and exhaustive beta
test period, WinSIGNAL94 is now shipping! With its introduction,
SIGNAL94 now becomes one of a limited number of traffic
operations programs available in the graphical Windows
environment, and the only signal operations and capacity analysis
program available for both DOS and Windows! Supported
platforms include Windows 3.1, Windows 95 and Windows NT,
as well as continuing support for DOS. This Windows
implementation incorporates a unique graphical user interface in
a new Visual Mode which makes the programs quite intuitive using
the familiar Windows environment. WinSIGNAL94 also retains the
powerful Manual Mode for "power users". Combined with
SIGNAL94's unique signal timing and phasing optimizer, this makes
SIGNAL94 an unmatched opportunity.
WinSIGNAL94 includes context-sensitive help
and a complete, on-line user guide with comprehensive
search capabilities, even under Windows 3.x. Data files for
WinSIGNAL94 are compatible with previous DOS versions of all
TEAPAC programs, including SIGNAL94, PREPASSR, PRETRANSYT,
PRENETSIM and SITE, and are interchangeable between
all operating system platforms. WinSIGNAL94 boasts 2-3 times
computing speed over its DOS counterpart. Also, the powerful and
unique Control File feature of TEAPAC is still available,
allowing continued use of WinSIGNAL94 for batch analyses
which perform multi-scenario, multi-file computations with
a single command.
WinSIGNAL94 is available from Strong Concepts
for the same price as the DOS version, $595. SIGNAL94 DOS
Licenses can be up-graded for $295, and licenses to SIGNAL85 can
be upgraded for $395. See some of the unique features of
WinSIGNAL94 on the next page.

|You Can Find TEAPAC Anywhere|
Of the seven continents of the world, active
TEAPAC licenses are in use in all but one -- Can you guess which
continent doesn't have a TEAPAC license? This widespread use is
also reflected in usage in the United States, where TEAPAC has
been licensed in all 50 states and is used by a majority
of Departments of Transportation in the U.S.A. and Canada. This
expansive usage is a testament to the proven power and usefulness
of TEAPAC. Having stood the test of time for over 20 years,
this suite of mature programs continues to be the most popular
privately-developed traffic and transportation package worldwide.
This is in part due to our highly-acclaimed support for
the programs which our users tell us is second to none! We
frequently provide support for other traffic software! If you are
not yet a member of this group of TEAPAC users, call us now so we
can get you on the road to unparalleled efficiency in your
|ITE Delegates Win Big!|
Four delegates at the ITE Annual Meeting came
home from the conference with more than they expected last fall.
They were winners in the free software giveaway at the Strong
Concepts exhibit hall booth, each winning a free, fully-licensed
copy of their choice of TEAPAC software. The winners were:
City of Boulder, Colorado
City of Fargo, North Dakota
Snyder & Associates, Ankeny, Iowa
City of Olathe, Kansas
Three of these picked the new WinSIGNAL94
program to enhance their ability to optimize signal timings and
phasings in an HCM capacity analysis. The other chose PRETRANSYT
as a powerful means to prepare TRANSYT-7F inputs in a reliable,
error-free manner, with the added ability to read these data
inputs directly from the SIGNAL94 program.
Congratulations to these winners, and good luck to everyone in next year's drawing. We expect to continue this annual event this August at the next ITE Annual Meeting in Boston.
|Courses Featuring TEAPAC|
The next hands-on software training courses
which feature TEAPAC will be offered in Orlando, Florida the week
of March 10-14, 1997. The first course, "Timing Traffic
Signals Using TEAPAC, PASSER, TRANSYT and NETSIM," has a
focus on specific solutions to signal timing and simulation
problems from isolated intersections and arterials to diamond
interchanges and grid systems. Hands-on work problems using the
software mentioned provide the user with real experience applying
these solutions with the only software system that integrates all
of these programs into a single system of software. The TEAPAC
programs used include SIGNAL94, NOSTOP, PREPASSR,
PRETRANSYT and PRENETSIM, in addition to PASSER-II,
TRANSYT-7F and TRAF-NETSIM. This very popular
three-day course will be offered at the University of Central
Florida March 10-12, 1997 in Orlando.
The three-day course will be followed
immediately by the two-day course "Advanced TEAPAC
Application Techniques" which provides hands-on
exercises for multi-file, multi-scenario analyses, batch analyses
and comprehensive multi-program integration using TEAPAC and the
above programs on March 13-14 in Orlando.
A four-day version of the first course called "Microcomputers
Applications in Signal Timing" adds related survey
techniques and will be offered in Evanston, Illinois at the
Northwestern University Traffic Institute May 5-8, 1997.
Call Strong Concepts at (847) 564-0386 for more
course information. You may also call the Universities directly
for registration information:
University of Central Florida
Northwestern University Traffic Institute
(847) 491-5040 or (800) 323-4011
Call early, as these courses fill up quickly and enrollment is limited. All of these courses will have the option of using either the DOS or Windows versions of SIGNAL94.
|Update Approved for Chapter 9 of the Highway Capacity Manual|
At the January meeting of TRB's Highway
Capacity Committee, the Signalized Intersection Subcommittee
chaired by Dennis Strong gained approval to proceed with the
publication of an update to Chapter 9 of the Highway Capacity
Manual. This update will include a number of important
enhancements to the signals chapter, as outlined in the following
1) The measure of effectiveness used will now
be total delay rather than stopped delay, and the level of
service thresholds will be modified accordingly. New survey
techniques will also be used to measure this delay in the field.
2) An enhanced model for the effects of
actuation and coordination on delay will be used, based on
research recently completed. A new Appendix II will outline a
better way to estimate the "average" fixed-time timings
for an actuated signal.
3) A new formulation for the delay equation
will allow its evaluation for over-saturated conditions. This
formulation will also allow the evaluation of delay for an
analysis period that has an initial queue, as well as a
4) Lane utilization adjustments will be made to
saturation flow rate rather than volume so that imaginary
vehicles are not introduced into the analysis as they presently
5) Some adjustments to the permitted left turn
model have been made to better reflect some of the permitted left
turn conditions which may be observed.
6) Clarifications are given as to when it might
be appropriate to use the "CBD" adjustment factor.
7) Better usage of lost time in the chapter is
provided, primarily with the clarification of the inclusion of
all-red time as part of the lost time.
8) Minor errata from the 1994 version of the
Chapter is corrected.
Publication of the updated Chapter 9 is anticipated at the end of 1997, in conjunction with updates to Chapters 3 (Freeways), 10 (Unsignalized) and 11 (Arterials). A Metric User Guide for the HCM which provides guidance for conversion of analyses to metric will also be published concurrently.
