TRAFFIC INFORMATION PROCESSING SYSTEM: ADVANCED TRAFFIC CONTROL SYSTEM OF TOKYO METROPOLITAN POLICE DEPARTMENT

The traffic information processing system supports the fundamental traffic functions of the traffic control system, such as signal controls, information provision, and traffic management to find out, control, and rule on the current traffic situation at the traffic control center. The system processes information from about 14,000 units of vehicle detectors installed along over 2,100 km of arterial roads in the Tokyo Metropolitan area to produce various kinds of traffic information on congestion, travel time, and so on. Information on congestion and travel time is important to drivers as it lets the driver know the expected arrival time or delay time through congested sections. This system also accumulates that traffic information with additional information transferred from facilities of neighboring prefectures and highway centers, and manages short-term and long-term statistical data for as many as 1,500 main intersections and 6,000 main sections. This paper describes: 1) the estimating method for queue length, 2) the estimating and predicting methods for travel time, 3) results of their verifications of estimated and predicted travel time, and 4) accumulating and statistical processing methods.
