This report provides a systematic method of identifying and evaluation sites for arterial street sampling detectors to compliment computerized traffic control on arterial streets. The research literature failed to identify significant written documents on the locations of arterial detectors. Contacts with several signal manufacturers and many engineers who have designed computerized signal systems produced no consistent method for detector location. One of the most significant findings is that the cost of detailed volume counts and correlations with downstream traffic problems commonly exceeds the cost of installing detectors at all tentative locations. The data collection and correlation can then be accomplished using the system. Recommended average sampling detector spacing is 800 meters (one-half mile) along the controlled arterial street.

This handbook, which was developed in recognition of the need for the compilation and dissemination of information on advanced traffic control systems, presents the basic principles for the planning, design, and implementation of such systems for urban streets and freeways. The presentation concept and organization of this handbook is developed from the viewpoint of systems engineering. Traffic control studies are described, and traffic control and surveillance concepts are reviewed. Hardware components are outlined, and computer concepts, and communication concepts are stated. Local and central controllers are described, as well as display, television and driver information systems. Available systems technology and candidate system definition, evaluation and implementation are also covered. The management of traffic control systems is discussed.

This report summarizes results of a study of detector placement on the diamond interchange frontage road (ramp) using the Texas Intersection Simulation Model. The criterion used for the optimization is the minimization of delay. A secondary criterion is to reduce the dilemma zone to a minimum. The results indicate that the first detector located along the frontage road (ramp) should be placed about 30 meters (100 feet) back from the stop bar. The remainder of the layout should provide a vehicle interval between 1.1 and 1.3 seconds and not trap a vehicle a the design speed in a dilemma situation. The recommended layout of detectors achieves these two goals.

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. This handbook is a supplement to Final Report (FHWA No. 75-92) for the detector locating project.

The study was undertaken to improve understanding of how to place vehicle detectors at high-speed (at least 35 mph), isolated, traffic-actuated intersections, and how to test and evaluate alternative detector/controller configurations for intersection traffic safety and efficiency.
