METHODOLOGY OF VEHICLE DETECTOR INSTALLATION ARRANGEMENTS IN AN URBAN TRAFFIC CONTROL SYSTEM

Japan's traffic control systems use a large number of vehicle detectors which collect information on traffic conditions for tasks such as signal control and provision of information services. This paper describes the present arrangement of vehicle detector installations as well as their problems, and also presents a discussion on future arrangement methods. Detectors are installed for signal control, depending on the type of signal control required such as signal pattern selection according to the value M, the split value calculated from the saturation ratio, and various adaptive control schemes. Detectors are installed for information services, depending on the traffic conditions and how the branching ratio is to be determined. Regarding the traffic characteristics the intersections must be carefully considered. Several vehicle detector types each having different characteristics have been developed. These include infrared detectors, image processing detectors, ultrasonic detectors, and loop detectors. In actual detector installations, practical conditions such as landscape, maintenance, installation work, and cost must be considered, so ideal arrangements are not always possible. Thus, vehicle detectors, the "eyes" of traffic control systems, need to be arranged considering various practical as well as theoretical aspects. In this research, using Fukuoka City and Tokyo as examples, the present arrangements of vehicle detectors have been studied and their problems identified. The obtained results should help define what detector arrangements and type are desirable in the future.
