LOCATING DETECTORS FOR ADVANCED TRAFFIC CONTROL STRATEGIES. HANDBOOK

This report is a handbook for locating detectors for advanced traffic control strategies. A discussion of criteria is presented and procedures for locating detectors to provide required surveillance data are described. The procedures relate to locating detectors at critical intersections, assessing which link in the network requires detectorization, and locating detectors within the link. Both latitudinal and longitudinal placement within the link are discussed. The procedures were developed as part of the continuing research for the Urban Traffic Control System/Bus Priority System (UTCS/BPS), in Washington, D.C., but are applicable to the more general detector locating studies for traffic control systems. This handbook is a supplement to the Final Report for the detector locating project. The final report includes the study procedures and results for the UTCS/BPS network. The final report volume is FHWA No. 75-92. /FHWA/
