An Urban Traffic Control System (UTCS) which will be installed in a portion of Washington, D. C. has been designed and specified. This system provides the means for the on-street testing of advanced control strategies as well as for field studies of traffic flow characteristics. The system's elements include on-street vehicle detectors, communications equipment to carry vehicle detector information to a central site, a computer which processes the information to determine optimum signal patterns, and signal controllers to change the signals in response to computer commands. The study areas were: Algorithms to compute the costs of traffic delays and stops; detectorization of parking garages with the objective of relating their ramp counts to the UTCS queue algorithm; development of concepts for measuring turning movements and intersection blockage by appropriate detector placement and synchronization with signal timing; development of concepts for handling multiple phase intersections in the critical intersection routines; incorporation of a portion of New York Avenue into the existing UTCS/BPS structure.
