Real-Time Application of Passer IV: Project Summary and Guidelines (1477-S)

PASSER IV is a program for timing traffic signals in networks based on progression bandwidth optimization. It is capable of optimizing signal timings for arterials as well as multi-arterial closed-loop networks. This report presents a summary of work conducted under a three-year research project funded by TxDOT. It provides guidelines for using PASSER IV as a 1.5 generation real-time traffic control system using a test-bed from the city of Richardson, Texas. In addition, the report addresses the issue of signal timing transition and provides the description of a preliminary algorithm for finding the cost of transition. Finally, the report provides new PASSER IV developments and describes new features.
