DEVELOPMENT OF A NEW MULTI-PURPOSE IMAGE PROCESSING VEHICLE DETECTOR AND ITS IMPLEMENTATION IN THE TOKYO METROPOLITAN TRAFFIC CONTROL SYSTEM

A new Image Processing Vehicle Detector (IPVD) which can detect traffic incidents and illegally parked vehicles as well as measure traffic flow and track vehicles across lanes has been developed and introduced for practical use in the Tokyo Metropolitan Traffic Control System. The compact IPVD unit is installed at the roadside and processes video images received from a CCTV camera. A total of four lanes of traffic can be measured. The camera is installed above the road surface on a three meter arm attached to a 10 meter high pole resulting in easy installation and maintenance while still maintaining a good line-of-sight for the camera. The detector provides accurate data on vehicle presence, speed, time of occupancy, vehicle type and incidents under various environmental conditions (day, night, twilight, rain, etc.). The system can be set up to measure either oncoming or departing traffic as well as both simultaneously in situations where two-way traffic measurements are required. The IPVD has been installed at 232 sites in the Tokyo Metropolitan area, making it the largest single installation of a video based detection system known to the authors.
