HY-24, DBRM MODEL, Version 4.0
The design hydrographs by the Drainage Basin Runoff Model
(DBRM Model) contain a program for the computation of a runoff hydrograph
from a complex basin. Hyrographs of runoff from various sub-basins comprising
the total basin are computed by application of rainfall-excess to unit
hydrographs of each sub-basin and then combined and routed through channel
and/or reservoir to produce the total basin hydrograph.
Rainfall-excess increments are computed by a modification of the standard
Soil Conservation Services (SCS) runoff curve equations. This modification
accounts for runoff from three sources—the urban directly-connected
impervious area (DCIA), the urban pervious (grassed) and non-directly
connected impervious area, and the rural portion of each sub-basin or
from each source only. The unit hydrograph used was developed from equations
originated by James A. Constant (formerly Chief Reservoir Regulation Section,
Corps of Engineers). These equations produce unit hydrograph almost identical
to the standard SCS unit hydrographs. Channel routing is accomplished
by the Muskingum method. A program for computing the time of computation
is also included.
The DBRM Model produces results almost identical to those of HEC-1, HEC-HMS
and TR-20 if the same input parameters are used. This software has been
accepted by FEMA for flood plain information studies.
Requires: Windows 95, 98, 2000,
ME or XP.

HY-34, HEC-HMS, Version 2.2.0
The Hydrologic Modeling System HEC-HMS Version 2.1.3 was released for
general use in November 2001. A number of defects have been found and
repaired since that release. New capabilities have also been designed
and added to the program. The resulting release, labeled Version 2.2.0,
is available from PC-TRANS.
Significant new features have been added to the reservoir element. It
is now possible to specify a low-level outlet, ogee or broad-crested spillway,
level or non-level dam overflow, and dam break as part of the reservoir
element. The new features use the new elevation-storage or elevation-area
options. The old features using the storage-outflow, elevation-storage-outflow,
or elevation-area-outflow options are still available.
Other new program features include support for the MS Windows clipboard,
minor enhancements to the standard project storm, improved HEC-1 import,
impervious area for the soil moisture accounting loss method, and the
straddle-stagger reach routing method.

SU-9, GPS2CAD 2.5
This new version contains two major improvements:
l It now works with most of the Garmin hand-held units, including the
popular eTrex line, which was most requested by users; and
l It comes with improved printing capabilities for the points in the GPS
grid and CAD grid.
Also available is a new recreational version (GPS2CAD-rv) that allows
you to connect your hand-held GPS Receiver to your computer and download
Waypoints and Trackpoints maintained by GPS Receivers. Waypoints are points
entered manually with the push of a button on the GPS Receiver’s
faceplate, and Trackpoints are points that show the actual walk-around
history of the user’s location. Waypoints are generally accessible
for review on the GPS display, but Trackpoints are typically hidden from
the user except to plot them in a connect-the-dot display.
With GPS2CAD-rv, both of these point files can be retrieved and plotted
with lines, points and blocks directly into AutoCAD. While it does not
have some of the features of the full version, it maintains all the essential
core functions. It also works with AutoCAD 14, 2000 and 2000i. Satellite
navigation and site layout are now made much more convenient by outputting
to an AutoCAD file.

TE-17 TRANSYT-7F, Rel. 9.6
TRANSYT7-F is a complete traffic signal timing optimization
software package for traffic networks, arterial streets, or single intersections
having complex or simple conditions. It offers enhancements to the modeling
of traffic-actuated control and cycle length optimization, ability to
view extensive simulation details, improved interface/output appearance,
plus integration with HCS and CORSIM.
The release 9.6 features genetic algorithm (G.A.) optimization of cycle
length, phasing sequence, splits, and offsets, using either TRANSYT-7F
or CORSIM as the simulation engine. Genetic algorithm optimization is
a theoretical improvement over the traditional hill-climb optimization
technique that has been employed by TRANSYT-7F for many years. The genetic
algorithm has the ability to avoid becoming trapped in a "local optimum"
solution, and is mathematically best qualified to locate the "global
Optimization of phasing sequence on both the major and minor streets can
be handled using the genetic algorithm (G.A.). During optimization, TRANSYT-7F
examines virtually all feasible phasing sequences including leading and
lagging left-turns with and without overlap, lead-lag phasing, and split
phasing. The program is designed to be equally effective in optimizing
phasing sequences for networks with left-hand driving (e.g., having leading
or lagging right-turns).
The user may allow full optimization throughout the network, but can also
specify restrictions on optimization at any approach of any intersection.
On every approach, the user may specify whether they wish to allow optimization,
overlap phasing, lead-lag phasing, leading through movements, or the "yellow

TE-34, PASSER II-02, Version 1.0
The new release of a Windows upgrade to PASSER II software,
which develops optimal progression along signalized arterials having multiple
arterial phase sequences is now available. This new release (PASSER II-02)
has a new user interface similar to PASSER III-98. It also has an enhanced
optimization routine used by its predecessor, PASSER II-90. The input
data requirements have not changed; however, unlike the previous release,
it preserves the lane configurations supplied by the user. This was achieved
by introducing a new format for the input data file. The program can read
old input data files and will automatically convert them to the new format.
Because a large user-base exists, the old output report from PASSER II-90
(now the "Classic" output) can be selectively displayed and
printed. PASSER II-02 user interface provides several new features as
l updated saturation flow calculation module;
l summary of results for all cycle lengths analyzed;
l user can view output for any selected cycle length;
l generates output reports in rich text format and launches Microsoft
WinWord for viewing these;
l new time-space diagrams in html format, and viewed by automatically
launching Microsoft Internet Explorer; and
l advanced Help facility.
The enhanced optimization routine now produces integer-only green splits.
This new version will be available from PC-TRANS soon.

TE-36F, WARRANTS/TEAPAC, MUTCD 2000 Warrant Analysis
The WARRANTS2000/TEAPAC program (#TE-36F1) now performs
multi-way stop warrant analyses in addition to its signal warrant analyses,
both according to the procedures dictated by the MUTCD 2000 (Millennium
In addition, an option has been added for user-selection of the so-called
56 percent rule for the combination of warrants used in a 2000 Signal
Warrant Analysis. WARRANTS2000 continues to provide an option to perform
a signal warrant analysis using the previous MUTCD (1988). WARRANTS2000
performs its multi-way stop and signal warrant analyses using all the
volume-oriented warrants of the MUTCD 2000, including warrants 1A, 1B,
1C, 2, 3A, 3B and 7 for signals. A unique algorithm searches every possible
60-minute period of a 15-minute count for hours that meet the warrants,
ranking the identified hours by minor street volume. Input data can be
imported directly from various electronic traffic counters such as Jamar
and TimeMark or entered/ edited manually. The 2000 warrant analysis enhancements
are also built into the Usage Level 2 version of TURNS/ TEAPAC (#TE-36E2).
Usage Level 2 of WARRANTS (#TE-36F2) also provides advanced tabulation
and peak hour analysis features. Peak 15-minute or 60-minute volume data
can be sent directly to other TEAPAC programs like SIGNAL2000 for optimized
HCM level of service calculations, SITE for background traffic in impact
studies, and PREPASSR, PRETRANSYT and PRENETSIM for signal timing and
modeling studies. Use of the TED and TUTOR programs in the TEAPAC system
allow complete automation of all of these calculations for unparalleled
efficiency, accuracy and speed.
WARRANTS has a unique Visual Mode, which provides an intuitive, Windows
graphical user interface, as well as a Command Mode for power users. This
is the same WinTEAPAC2000 interface found in all other TEAPAC programs.
This interface includes a fully indexed, on-screen user guide and context-sensitive
help and error diagnostics. WARRANTS also incorporates the new TEAPAC
Version 5 interface with its Tabular View to increase efficiency for intermediate
users and certain data-intensive tasks.
The Warrant Analysis version of WARRANTS/TEAPAC Ver. 2.01 from Strong
Concepts (#TE-36F1) is available from PC-Trans for $395. The Usage Level
2 version, (#TE-36F2), which adds advanced tabulation and peak hour analysis
features is available for $595. Educational versions are available for
half-price and demonstration versions are available free as downloads
from the Strong Concepts and PC-Trans web pages. Free and reduced-price
updates are available for registered licensees of earlier versions of
WARRANTS and TURNS directly from Strong Concepts.
TE-36D & TE-36G, PRETRANSYT/ TEAPAC & PRENETSIM/TEAPAC
PRETRANSYT and PRENETSIM, for the TRANSYT-7F and CORSIM
traffic models have been vastly enhanced to include many advanced modeling
capabilities which are available in these time-tested, government-sponsored
models. These enhanced capabilities provide for efficient and reliable
execution of traffic system modeling, optimization and animation projects.
l sign-controlled movements;
l startup lost time and end gain time by movement;
l storage capacities by movement;
l alternative upstream-downstream assignment method (TRANSYT);
l dual-optional lane usage;
l link curvature (CORSIM);
l free flow lanes;
l number of lanes;
l heavy vehicle percentages
Other enhancements include:
l increased limits on allowed map coordinate values to accommodate larger
scale coordinate systems;
l ability to read all of these model parameters directly from SIGNAL2000
for true HCM-based intersection capacity analysis and optimization;
l compatible changes made in PREPASSR for PASSER-II;
l better simulation time period management (CORSIM);
l option to enter executable file name in setup CFG file;
l better permitted left turn modeling (TRANSYT);
l fine-tuning of the new Version 5 TEAPAC interface.
PRETRANSYT and PRENETSIM both have the unique TEAPAC Visual Mode, which
provides an intuitive, Windows graphical user interface, as well as a
Command Mode for power users. This is the same interface found in all
other TEAPAC programs. This interface includes a fully indexed, on-screen
user guide and context-sensitive help and error diagnostics. PRETRANSYT
and PRENETSIM also incorporate the new TEAPAC Version 5 interface with
its Tabular View to increase efficiency for intermediate users and certain
The 12-intersection versions of PRETRANSYT/TEAPAC Ver. 2.71 (#TE-36D1)
and PRENETSIM/TEAPAC Ver. 1.31 (#TE-36G1) from Strong Concepts are available
from PC-Trans for $495. The Usage Level 2 versions, (#TE-36D2 and #TE-36G2),
which handle up to 100 intersections with subsystem management are available
for $695. Educational versions are available for half-price and demonstration
versions are available free as downloads from PC-Trans web pages. Free
and reduced-price updates are available for registered licensees of earlier
versions of PRETRANSYT and PRENETSIM directly from Strong Concepts.
Strong Concepts announces the first major upgrade of its
SIGNAL2000 program since its original release. The upgrade is concurrent
with the 2000 Highway Capacity Manual (HCM). The major changes to SIGNAL2000
l Handling up to 500 intersections in one file with a single click. If
you are working with a single intersection, trying different geometric
designs with repeated optimizations for an impact analysis, or an intersection
design, you can keep your focus on that single intersection, as before.
But projects frequently call for a re-analysis or re-optimization under
new assumptions where managing all intersections and/or all scenarios
individually becomes very time-consuming. SIGNAL2000 Version 2 has the
ability to manage the data for up to 500 intersections in a single file,
and to execute HCM capacity analyses and full timing/phasing optimization
for all intersections with the press of a single button.
Version 2 is compatible with old data files, and it's easy to combine
multiple data files from Version 1, SIGNAL97, or even SIGNAL94 into a
single file for Version 2.
l Seamless integration of SIGNAL2000 data with PRENETSIM, PRETRANSYT and
PREPASSR. One of the advantages of the new multi-intersection analysis
option is the ability to seamlessly integrate its data with the PRENETSIM,
PRETRANSYT and PREPASSR elements of the TEAPAC software package.
PRENETSIM manages the interface between the TEAPAC data inputs and the
more complex inputs required by CORSIM, developed by the Federal Highway
Administration (FHWA) for simulation and animation of street networks.
PRETRANSYT performs the same function for the TRANSYT-7F program which
simulates traffic on a signalized network, while also providing a time-proven
method for optimizing the coordinated signal timings.
PREPASSR provides a similar function for the popular PASSER-II program,
including the latest PASSER II-02 Windows Version of PASSER-II.
These programs easily share their data files and results
with each other including the optimized parameters. For example, PASSER's
optimized offsets can become TRANSYT's starting offsets, and the timing
plans generated from either can be easily simulated and animated with
These programs have always been able to read the data files of SIGNAL2000
(and SIGNAL97, SIGNAL94 and SIGNAL85), but with SIGNAL2000 Version 2,
the user is only one click away from a CORSIM animation or a TRANSYT or
PASSER optimization for a complete system analysis.
l Accurate treatment of NEMA-style, dual-ring controllers. A troubling
problem for some users of the Highway Capacity Manual (HCM) has been an
apparent difficulty in representing timings for NEMA-style controllers,
especially when there are small differences between the times allocated
to left turn phases. Version 2 of SIGNAL2000 has the ability to resolve
this problem by representing negative phase times. The user can quickly
switch his/her view of the phase timings either from the perspective of
the HCM (timings by phase) or to a NEMA-style controller (timings by movement),
by virtue of the new dual-ring diagram displayed on the screen. The optimizer
in SIGNAL2000 is now also able to take advantage of this new represention
of timings to maximize the capacity of a signalized intersection via timing
and phasing optimization.This produces the only available true-HCM optimization
of dual-ring controllers.
l Major enhancement to optimization method for signal timing and phasing.
The fundamental optimization strategy used in SIGNAL2000 goes back to
the first version of SIGNAL which optimized delay. This new version of
SIGNAL2000 gives the user much better control of the optimization process.
For example, users could previously specify the level of service (LOS)
to be targeted for the critical movements of each phase. Now that feature
has been expanded to allow the user to enter the specific amount of delay
targeted for the
critical movements as an alternate to the level of service. This allows
two significant improvements over the previous method:
—A specific value of delay between two LOS boundaries
can be targeted, rather than just the actual LOS boundaries, and
—Delay values greater than the arbitrary limit of 80 seconds for
LOS E can be targeted.
This offers significantly superior control over the delay targets, a frequent
requirement for specific situations and design policies. Further, the
increment of delay can now be specified, and will be used during the optimization
process when the target delay cannot be met, permitting much more precise
balancing of the critical movement delays.
In addition, the user may specify a limiting value of delay which, when
exceeded in the design, will switch the optimization strategy over to
a v/c optimization, with targeted v/c limits and increments specified
by the user (similar to the delay targets). When desired, the user can
also force this v/c optimization to be used without regard to the delay
of the critical movements.
Also, the allocation algorithm to prioritize specified movements has been
improved including the special condition when right turns are critical.
l Graphical view of network with optional bitmap aerial or map background.
A new table of optimization results can be produced showing the critical
delay and/or v/c achieved for each combination of optimum cycle length
and phasing. The selection of the optimum cycle from these results more
precisely identifies the best cycle. The minimum cycle length is also
determined and displayed.
Licensees of SIGNAL2000 Version 1 can upgrade to Version 2 at a discounted
price; i.e. $295 for upgrading a typical 12-intersection Version 1 to
Version 2 (100- and 500-intersection versions are also available as upgrades.)
New licenses for the 12- 100- and 500-intersection sizes cost $595, $695
and $795, respectively. All TEAPAC licenses are automatically site licenses
for all computers at the licensed address.

TE-47, aaSIDRA, Rel. 2.0
aaSIDRA 2 is the major new version of the popular intersection
analysis software by Akcelik and Associates. It is an advanced analytical
tool for evaluation of alternative intersection designs in terms of capacity,
level of service and a wide range of performance measures including delay,
queue length and stops for vehicles and pedestrians, as well as fuel consumption,
pollutant emissions and operating cost.
The new features of aaSIDRA 2 include new output graphics in full Windows
environment including intersection geometry, signal phasing and movement
statistics displays, major traffic model enhancements, and various other
input and output enhancements.
New output graphical displays introduce many improvements including detailed
geometry pictures for roundabouts and all intersections with diagonal
legs, a larger range of output statistics displayed, and phasing displays
with phase time information. Full color, low color and monochrome options
are available. All graphical displays as well as the new HTML-style text
output are based on an XML data file developed for aaSIDRA.
Traffic model enhancements in aaSIDRA 2 include:
l introduction of HCM 2000 model defaults including major revision of
the aaSIDRA US metric version based on the HCM 2000 metric edition defaults;
l extensive update of default parameters including major revision of defaults
for operating cost, fuel consumption and emission estimates based on 5
light vehicle and 5 heavy vehicle classes;
l revised acceleration and deceleration models for all types of intersection;
l improved models of through and turning vehicle negotiation characteristics
(negotiation radius, distance and speed) at roundabouts;
l revised model of slip lane capacity at roundabouts;
l use of new pedestrian level of service criteria based on HCM 2000, which
are different from vehicle level of service criteria;
l enhanced pedestrian queue space modeling;
l space occupancy ratio for continuous movements;
l revised method of aggregating movement delays from lane delays in relation
to the way geometric delays are handled; and
l improved handling of progression factors for signal coordination effects
on delay, queue length and other performance statistics.
New models of vehicle paths at roundabouts, and the general revision of
acceleration and deceleration models will have a significant effect on
geometric delays, and therefore on control delays. These as well as other
changes to default parameters will amount to significant changes in operating
cost, fuel consumption and emission estimates.
Requires: IBM compatible PC (Pentium II 500 MHz or better); Windows 98,
Me, NT4, 2000, XP; Internet Explorer version 5 or later; Minimum 64 Mb
RAM; CD drive for installation; and Graphics card with hardware OpenGL
support and the latest drivers to suit, running at least 1024 x 768 resolution

TE-48, TS/PP-Draft Version 5.0
This new version of the Time-Space and Platoon-Progression
software has the following new features:
l You can now annotate the diagram window -- put notes of any length,
in any font size and style, anywhere on the diagram;
l In the Options dialog, you have greater control over the Layout of the
Diagram. You may label the Splits with either arrows or two-letter abbreviations.
You may display the Offset on staggered lines below the intersection names
or next to the Offset Reference Point in the diagram to reduce clutter.
You may show just one band in each direction, and you may color-fill the
bands to make them stand out. You can show minor Time Markers (ticks or
grid lines) in addition to the regular (major) time markers;
l Offsets are no longer constrained to reference a movement along the
arterial in the diagram—they may reference movements along the cross-street;
l It is now easier to set and manage split phasing with the new protected
phase sequence options "Split-Lead" and "Split-Lag";
l Printing and general operation under Windows 2000 and Windows XP has
The biggest new features kick in if you have access (or can get access)
to a GPS receiver. Just connect a compatible GPS receiver to your computer
and let TS/PP-Draft track position and speed. TS/PP-Draft can use this
l Determine the geographic positions of intersection. From this, TS/PP-Draft
can calculate the distance between intersections, and lay out the Network
View with high accuracy;
l Track your current location in time and space and display it on the
diagram window and in the Network View;
l Predict whether you will arrive at the next signal during the green
time. If you wish, it will play different sounds to indicate you're projected
to arrive a bit early or late, or a bit too early or too late;
l Record Trip Logs of travel along the artery. Trip Logs can be used to
o Plot trajectories on the diagram windows, graphically showing where
delay occurs, which signals you are stopped at, and where you enter or
leave the green bands. Before and after trip logs may be recorded in the
same diagram data file, and you may select which ones are visible at any
l Prepare Travel Time and Delay Reports, which can easily be copied and
pasted into word-processing documents or spreadsheets for detailed analysis.
These can be very powerful tools of analysis for determining the effectiveness
of a timing plan.
l Measure the actual travel distance between intersections.
l Calculate the "optimal" relative offset between intersections
for a given direction of travel.
l Calculate the actual average speed between intersections.
A sample diagram data file included with version 5.0 shows Trip Logs plotted
as trajectories and available for the Travel Time and Delay Reports and
Compatible GPS receivers include any receiver that complies with the NMEA
(National Marine Electronics Association) 0183 Standard, or the Earthmate
from DeLorme (available for around $125). The majority of GPS receivers
comply with the NMEA 0183 Standard. TS/PP-Draft has been tested with GPS
receivers from Magellan and Garmin and they all work great.

enhanced micro-simulation of traffic flow at the intersection providing
additional traffic measures beyond those in the HCM, and colorful animation
displays of vehicle movements. As in previous versions, all these features
are integrated, requiring no file manipulation by the user. Many new features
are incorporated in this release including:
l ability to analyze effects of parking along the left curb on one-way
or on two-way streets with a concrete median divider;
l ability to analyze effects of pedestrian on both left- and right-turning
l ability to analyze effects of bicycles on right-turning traffic;
l ability to specify each signal phase as either pre-timed or actuated;
l analyzes and identifies Back Of Queue (BOQ) information for the 70th,
85th, 90th, 95th and 98th percentiles simultaneously in a single run;
l offers high quality output reports in both the new HCM 2000 format and
the traditional HCM format familiar to most users.

TO-20, Bus Transit Garage Space Requirement Model, Version 6.0
This software prepares a detailed space program for bus
transit garages. It can generate a list of 59 elements that are part of
a transit garage with the number of square feet required for each. The
program also lists the required number of repair bays, bus stalls, and
paint and body bays.
The space program is broken down into five major areas including General
Offices, Operations Area, Repair Area, Vehicle Storage (indoors and outdoors),
and Outside Area. The model handles any bus fleet size from five to 350
buses with any mix of 30-, 35- and 40-foot buses as well as articulated
buses and paratransit vans.
This new version runs on Windows 95 or higher. It contains detailed Help
Screens and comes with a printed User’s Manual. The User’s
Manual for the new version includes Linkage Diagrams for the Major Facility
Elements, Daily Service Cycle, and Major Area Elements. It also identifies
Space Utilization Characteristic for every element in the garage.

TE-73, QuickZone, Version 1.0
To address mobility and safety impacts of work zones, the
Federal Highway Administration (FHWA) has initiated a program called Strategic
Work Zone Analysis Tools (SWAT). As part of this program, the following
four new tools for the design and operation of work zones are to be developed:
l Work Zone Delay Impact Analysis spreadsheet;
l Expert System software program;
l Cost/Alternative Analysis spreadsheet; and
l Detailed simulation model
QuickZone, developed by Mitretek Systems, is the first product of SWAT
program. It compares the traffic impacts for work zone mitigation strategies
and estimates the costs, traffic delays, and potential backups associated
with these impacts. The software can help State and local traffic, construction,
operations, and planning staff, as well as construction contractors, be
aware of the effect that different work zone phasing has on the motorists
from both a cost and delay standpoint.
The software provides information in a spreadsheet form and can accommodate
networks with up to 100 nodes and 200 links. To run the program, the user
would enter data on the planned work zone such as location, projected
detour routes, anticipated traffic volumes and construction dates and
times. The program then displays the amount of delay in vehicle hours,
the maximum length of the projected traffic queue, and the costs associated
with the work activity.
QuickZone can also analyze the advantages of various strategies for minimizing
the projected traffic delays. These mitigation strategies might include
retiming signals on detour routes to help traffic flow more smoothly,
planning a media campaign to publicize the planned work zones, or using
traveler information systems that allow drivers to plan ahead and choose
other routes if possible.
Requires: Windows 95 and Microsoft Excel 97 or higher. Program run times
change from 3 minutes on a computer with a Pentium 166 to 1 minute with
a Pentium 400.
TE-73, version 1.0, $195
WinTURNS, developed by Rick Ernstmeyer, is a shareware
program designed to create turning movement diagrams. It uses an iterative
approach to balance the inflows and outflows of an intersection as described
in NCHRP Report 255, Highway Traffic Data for Urbanized Area Project Planning
and Design, Chapter 8. This same technique works well when expanding observed
short-term manual intersection counts to turning movement diagrams on
rural intersections. In both scenarios, your final result is a solution
that shows the distribution of traffic by individual turning movements
through an intersection.
The program was created to handle intersections of 3 to 8 legs, with the
ability to select from any of the 8 standard direction codes. The form
will only display boxes for the number of legs in your intersection. It
calculates and displays the results for the current year’s Average
Daily Traffic (ADT), some forecast year’s ADT and some year’s
Design Hourly Volume (DHV).
WinTURNS is broken down into 9 different forms:
l introductory form;
l initial data entry form;
l forms to enter observed or estimated turning information by individual
l forms where you can ‘lock in’ individual movements;
l form showing, in effect, a trip table of the results; and
l form showing the results as a turning movement diagram.
Requires: This program was created with Visual Basic 5.0 and is a 32-bit
application. As such, it can only be run on either the Windows 9x or Windows
NT operating systems. It cannot be run on a 16-bit Windows system. It
was developed on a machine running Windows 95, with 32 Meg of RAM and
a 133 MHz processor. It was tested on a machine running Windows NT. It
is required that you are using a minimum screen resolution of 800x600.
Higher resolution is recommended.
