Universal traffic management system (UTMS) in Japan

Abstract

Universal traffic management system (UTMS) is a new and comprehensive project that includes an integrated traffic control system, advanced mobile information system, mobile operation control system, dynamic route guidance system, public transportation priority system and environment protection management system. The National Police Agency, Japan (NPA), which governs the Japanese traffic management, has been promoting to introduce an advanced traffic management system called UTMS. UTMS is based on a broader concept like the IVHS in the United States and the DRIVE in Europe. From the viewpoint of traffic control using an automatic control system, this paper deals with four categories: the optimum control of the signal control system, the traffic information service system, the advanced traffic control system supported by a traffic data acquisition system, and the goal of UTMS.<>
