An Estimation Method of Congestion Length Using Pulse Data of Vehicle Detector

This paper introduces an estimation method of congestion length using pulse data of a vehicle detector. The Tokyo Metropolitan Police Department (MPD) has strived to develop its traffic control method to relief traffic congestion. High accurate estimation of traffic demand is one of the important factors for its development. The MPD uses vehicle detectors to measure traffic demands and estimates congestion length based on the degree of congestion. But this method can’t measure it precisely. Therefore, the MPD has introduced a method of detecting tail of congestion using pulse data of ultrasonic vehicle detectors to estimate congestion length precisely.
