VERIFICATION ON TRAFFIC FLOW CONTROL BY ITCS (INTEGRATED TRAFFIC CONTROL SYSTEMS)

Traffic accidents, congestion, and environmental pollution have become serious problems in Japan. Traffic control centers have helped to smooth traffic flow; however, the centers are approaching a limit of traffic flow control capabilities. More sophisticated traffic signal control systems are required. From the Universal Traffic Management Systems (UTMS) theory recently established, a new automatic parameter generation method was developed and installed in Kanagawa, Okayama, and Saga prefectures. The method can analyze and reflect to controlling signals actual events. In the new method, parameters of cycle and split are directly generated from data obtained from vehicle detectors. Compared to the conventional control method, the new procedure proved effective in shortening queue lengths and reducing travel time. To realize more effective control, however, additional control procedures including technologies to anticipate traffic flow change on the basis of season, day of the week, and time of day should be considered. This paper describes the system and highlights verification of the new control method by the three prefectural traffic control centers. Future solutions for realizing more smoothed traffic are outlined.
