UNIVERSAL TRAFFIC MANAGEMENT SYSTEMS (UTMS) IN JAPAN

UTMS is a system which aims at synthetic and upgraded traffic management including such sub-systems as: (1) Advanced Mobile Information System (AMIS); (2) Public Transportation Priority System (PTPS); (3) Mobile Operation Control System (MOCS); (4) Environment Protection Management System (EPMS); (5) Dynamic Route Guidance System (DRGS). As a whole, these sub-systems are integrated to form the Integrated Traffic Control System (ITCS), which is the core part of UTMS. ITCS will be realised by, for example: (a) optimum control of traffic signals; (b) a traffic information supply system using a variety of techniques; (c) the development of low cost traffic data acquisition techniques. It is also stressed that, as well as developing new approaches, UTMS will be created by fully utilising a huge number of existing infrastructures which the National Police Agency has been constructing. In Japan, an advanced and cost effective traffic management system which can produce the maximum results under a limited budget and personnel, is required. UTMS has been promoted by the Universal Traffic Management Society of Japan and the efficiency of the systems has been demonstrated through a series of experiments.
