Guidelines for Actuated Controllers in Coordinated Systems

Abstract

Research sponsored by the Texas Department of Transportation, Efficient Utilization of Actuated Controllers in Coordinated Traffic Control Systems, was used to develop a set of reliable control strategies to allow users to improve the overall design and operation of actuated controllers in conventional coordinated systems. The recommended analysis procedure can help users generate the signal timing parameters for coordinated arterial or network operations. Actuated, coordinated traffic signal system implementation will maximize the available resources for effective coordinated operations during undersaturated conditions, demand variations, and near-saturation conditions. The recommended coordination strategies and implementation guidelines for using actuated controllers effectively on coordinated signal systems are summarized. The study will effectively assist users in selecting the proper controller-detector combinations and improving system detector locations. It will also aid users in optimizing actuated timing parameters in actuated control operation of arterial signal systems.
