Traffic Signals and Systems
Using TEAPAC Complete, PASSER, TRANSYT and CORSIM
Optimal timing plans are essential to the proper evaluation of traffic signal planning, design and operation efforts and to assure efficient traffic movement on streets. Several nationally recognized traffic signal programs are available to assist the analyst in this regard. These include TEAPAC Complete, PASSER, TRANSYT and CORSIM. The goal of this course is to provide participants with a basic understanding of how to use these programs, both mechanically and procedurally, for signal evaluation and optimization efforts consisting of a wide range of signal control conditions, including individual signals and coordinated systems.
The course consists of lectures and hands-on use of microcomputers. Lectures cover the basics of traffic signal analysis and optimization techniques, demonstrations of the software and details of recommended procedures. Realistic numerical examples and hands-on exercise problems supplement the lectures, and the use of specific computer software provides participants with an opportunity to learn and understand the programs and procedures.
Dennis Strong is President of Strong Concepts, Greenville, SC. The firm's primary area of practice is in the development of integrated traffic engineering software and related training. Mr. Strong is a respected lecturer whose unique teaching style has been applauded world-wide, while at the same time a recognized expert in the analysis, evaluation, and operational design of traffic signals and systems, and in the development and use of computer software related to this field. He has 45 years of professional experience in these areas, and is the developer of the following software used in the course: TEAPAC Complete (SIGNAL, NOSTOP and Export/Import functions). Mr. Strong is a registered Professional Engineer (PE) in Illinois. He is also a past chairman of the Signalized Intersection Subcommittee of the TRB Highway Capacity and Quality of Service Committee, which authors the Highway Capacity Manual.
Software Used in Course
TEAPAC Complete from Strong Concepts performs capacity analyses which implement the calculation methods of the signalized chapters of the 2016 and 2000 Highway Capacity Manuals (HCM), as well as provides optimization of split timings, cycle length and phasings for the signal based on these HCM capacity analyses.
TEAPAC Complete from Strong Concepts provides simplified arterial bandwidth progression solutions, optimizing both system cycle length and offsets for two-way, prioritized progression.
PASSER II is a state- and federally-sponsored program from Texas, which optimizes offsets and splits for arterial progression over a range of cycle lengths. TEAPAC Complete prepares input for PASSER-II using the standard TEAPAC methods and analyzes the results in a clear and concise manner. Input can come directly from any other function of TEAPAC, if desired, allowing transfer of input and results between all aspects of the signal timing process.
TRANSYT-7F is a federally-sponsored program from McTrans, which optimizes offsets, splits and system cycles for arterial or network signal systems. TEAPAC Complete prepares input for TRANSYT using the standard TEAPAC methods and analyzes the results in a clear and concise manner. Input can come directly from any other function of TEAPAC, if desired, allowing transfer of input and results between all aspects of the signal timing process.
TRAF-NETSIM/CORSIM is a federally-sponsored program from FHWA, which performs microscopic, stochastic simulation and animation of a signalized network. TEAPAC Complete prepares input for NETSIM/CORSIM using the standard TEAPAC methods. Input can come directly from any other function of TEAPAC, if desired, allowing transfer of input and results between all aspects of the signal timing process.
