Abstract
This report provides guidelines and procedures for setting up a closed-loop traffic signal system to operate in a traffic responsive mode. It provides specific procedures for determining when two traffic signals should be coordinated. It also provides specific guidelines on when a closed-loop signal system should operate in a traffic responsive mode versus a time-of-day mode. Procedures are also provided for determining the thresholds that are needed to set up a system to operate in a traffic responsive mode. Finally, recommendations are provided on where to place system detectors to support the operation of a closed-loop signal system in a traffic responsive mode. (Author/publisher)
