MPD Traffic Control System, its Congestion Monitoring and Countermeasures

The Metropolitan Police Department Traffic Control System introduced STREAM, a new traffic signal control function, in 1995, resulting in 28% improvement of road congestion in the Tokyo Metropolitan Area compared with the previous year of 1994. From 2005, 10th year after its service commencement, annual goals have been decided to enhance each of its different functions including traffic information collection, traffic signal control and information provision. In order to maintain and fully utilize the performance of the Traffic Control System, it is essential to monitor and maintain the hardware state of roadside equipment such as vehicle detectors and signal controllers as well as the central equipment adequately by repair and adjustment. In addition, monitoring and analysis of traffic conditions such as traffic volume, congestion length, and travel time is requested to take appropriate measures such as adjustment of signal control. This paper focuses on the traffic condition monitoring, particularly on congestion monitoring and countermeasures, and discusses the past efforts and their effects as well as functions to be required in the future.
