VARIABLE CYCLE SIGNAL TIMING PROGRAM. VOL 1: DEVELOPMENT OF THIRD-GENERATION CONTROL POLICIES FOR THE UTCS

The objective of this effort was to develop advanced, "Third-Generation" Traffic Control Policies as part of the UTCS Project sponsored by FHWA. These policies are designed to be implemented on a system of urban streets by a digital computer, in real-time. To be responsive to short-term variations in traffic demand, these policies are designed to provide a continually changing pattern of traffic signal timings, unrestricted by the condition that all signals operate on a common background cycle. Separate policies are developed for each flow regime--light, moderate, and congested--and an adaptive predictor model is also presented. Detailed software documentation is provided for those policies recommended for implementation on the UTCS in Washington, D.C. Volume 1 presents an overview of the project effort including its background, objectives, underlying concepts, potential advantages and research approach. /NTIS/
