TEAPAC Products, Detailed Descriptions

Product Specifications...

All of the following traffic engineering and transportation planning functions are built directly into the TEAPAC Complete product:

SIGNAL is the keystone application of TEAPAC for signal analysis. The signal analysis function in TEAPAC performs both capacity analyses and signal timing/phasing optimization for signalized intersections in a manner strictly compliant with the 2016 and 2000 Highway Capacity Manual (HCM). Because of the unique optimizer in the program, it can be used to find the best possible level of service for projected conditions, such as in impact studies and design studies, as well as to determine the optimum timings and phasings to install in the field for current conditions.

SITE is the traffic impact analysis function in TEAPAC that calculates intersection turning movement volumes for any number of development scenarios of a single- or multi-use site. The user inputs development sizes, generation rates, directional distributions and assignment paths. Paths can be generated automatically with on-screen display. Several developments can be combined, and calculated volumes can be output directly to other analysis functions of TEAPAC such as signal analysis for rigorous Highway Capacity Manual optimization and design to determine the best possible level of service for projected conditions. Existing volumes can come directly from the TURNS peak hour analysis without further manual input.

WARRANTS is a count analysis function which performs a comprehensive signal and multi-way stop warrant analysis using all the volume-oriented warrants of the 2009/2003/2000 Manual on Uniform Traffic Control Devices (MUTCD 2009/2003/2000), including warrants 1A, 1B, 1C, 2, 3A, 3B and 7 for signals and A, B, C and D for multi-way stops. It also includes a 1988 MUTCD signal warrant analysis option. Every possible 60-minute period of the count data is searched, starting on each 15-minute interval. Volume inputs can be from count sheets or direct from electronic counters like the TURNS function, and non-volume inputs can be made for the other warrant conditions which must be met.

TURNS is a traffic count tabulation and analysis function which provides every conceivable analysis for turning count surveys. Tabulations include raw counts and 15-minute totals for the intersection and every movement, approach and exit as well as 15-minute volume rates and peak hour analyses which can be used directly by the other functions of TEAPAC for analyses such as signal timing studies and site traffic impact studies. Input can be with the built-in full-screen editor or directly from Jamar, TimeMark, Timelapse and Titan electronic counters.

NOSTOP is a simple-to-use arterial progression application in TEAPAC which sets offsets to maximize two-way bandwidths. It provides a powerful cycle optimization technique with graphical output to indicate the cycles which are best for the progression, and plots time-space diagrams of the results.

PRENOSTOP is one of six preprocessor functions in TEAPAC that make it an unprecedented tool for signal timing and progression studies. PRENOSTOP prepares input data for the NOSTOP progression function in TEAPAC using the same data of all the other TEAPAC applications. Since intersection timing and phasing are required inputs for NOSTOP, TEAPAC's signal analysis optimization is a logical means to get these inputs. In this case, the data already entered for the arterial can be used directly by PRENOSTOP so no additional input is required to run NOSTOP. TEAPAC also plots easy-to-understand time-space diagrams and signal timing tables of the imported NOSTOP results.

PRETSPPD is a preprocessor function in TEAPAC that make it an unprecedented tool for signal timing and progression studies. PRETSPPD prepares input data files for the TruTraffic and TS/PP-DRAFT programs using the same data of all the other TEAPAC applications. Since intersection capacity, timing and phasing are inputs for TruTraffic , TEAPAC's signal analysis optimization is a logical means to get these inputs. Using the seamless Export functions between TEAPAC and other timing programs like TRANSYT-7F, PASSER-II and Synchro/SimTraffic, coordinated timing plans are easily generated and passed to TruTraffic or TS/PP-DRAFT for display. In this case, the TEAPAC data for the arterial can be used directly for all the third-party programs so no additional input is required to run TruTraffic or TS/PP-DRAFT. It can also import offsets if they are manually changed within TruTraffic and TS/PP-DRAFT.

PREPASSR is a preprocessor function in TEAPAC that make it an unprecedented tool for signal timing and progression studies. PREPASSR prepares input data files for the PASSER-II program using the same data of all the other TEAPAC applications. Since intersection capacity, timing and phasing are inputs for PASSER, TEAPAC's signal analysis optimization is a logical means to get these inputs. In this case, the TEAPAC data for the arterial can be used directly by so no additional input is required to run PASSER. TEAPAC also plots easy-to-understand time-space diagrams and signal timing tables of the imported PASSER results.

PRETRANSYT is a preprocessor function in TEAPAC used to create input data files for TRANSYT-7F. It uses standard TEAPAC data input, and will use saturation flows and average signal phasings (both required inputs of TRANSYT) which were computed by TEAPAC, so TRANSYT can be run with no additional data input. It also plots time-space diagrams and displays complete signal timing tables of imported TRANSYT-7F results. In combination with TEAPAC's signal analysis optimization and other Export functions, all optimizations can be made from a single data base, making TEAPAC the most powerful and easy-to-use signal timing system. The seamless dat sharing also permits easy transfer of TRANSYT-optimized timings to other third-party programs like TS/PP-DRAFT.

PRENETSIM is a preprocessor function in TEAPAC used to create input data files for microscopic simulation and animation by either TRAF-NETSIM or CORSIM. It uses standard TEAPAC data input, and will use saturation flows and signal timings which were computed by TEAPAC (both required inputs of NETSIM/CORSIM), so NETSIM/CORSIM can be run with no additional data input. It also plots time-space diagrams and displays complete signal timing tables. In combination with TEAPAC's signal analysis optimization and other Export functions, all optimizations can be simulated and animated from a single data base.

PREVISSIM is a preprocessor function in TEAPAC used to create input data files for microscopic simulation and animation by either VISSIM or VISUM. It uses standard TEAPAC data input, and will use saturation flows and signal timings which were computed by TEAPAC (both required inputs of VISSIM/VISUM), so VISSIM/VISUM can be run with no additional data input. It also plots time-space diagrams and displays complete signal timing tables. In combination with TEAPAC's signal analysis optimization and other Export functions, all optimizations can be simulated and animated from a single data base.

PRESYNCHRO is a preprocessor function in TEAPAC used to create input data files for Synchro display and manipulation, as well as SimTraffic's microscopic simulation and animation. It uses standard TEAPAC data input, and will use saturation flows and signal timings which were computed by TEAPAC, and coordinated signal timings imported from other programs, so Synchro/SimTraffic can be run with no additional data input. It also plots time-space diagrams and displays complete signal timing tables. In combination with TEAPAC's signal analysis optimization and other Export/Import functions, all optimizations can be displayed, simulated and animated from a single data base. Furthermore, if a network has been input to Synchro/SimTraffic, the Network Import feature in PRESYNCHRO can import this entire network description for seamless transfer to all the other TEAPAC applications. This allows Synchro data to be further analyzed and optimized using time-proven, government-sponsored methods and software.

SCENARIO is the easy-to-use data file manager in TEAPAC designed to create and manage multi-issue scenario analyses without the burden and possible trauma associated with using File-SaveAs for scenario analyses.

TED is the built-in TEAPAC editor which can be used to make direct edits to TEAPAC data files, or to create multi-scenario batch analyses that can be run unattended.

TUTOR is the advanced tutorial manual for all TEAPAC functions. It contains many examples which can be executed directly with the program to learn the basic and advanced operating procedures which are available in TEAPAC.
