Abstract

The Comprehensive Automobile Traffic Control (CAC) Project was started in 1973 as a six-year project sponsored by the Agency of Industrial Science and Technology, Ministry of International Trade and Industry. The aim of this major project is to develop a comprehensive system for controlling the flow of vehicular traffic through the use of the most up-to-date computer and other technology for monitoring and controlling traffic in order to improve overall traffic conditions by reducing accidents, congestion, and air pollution and to relieve drivers of unnecessary mental stress. This paper presents some results of the feasibility study of this CAC system. Since route guidance plays the most important role in the CAC system, a detailed explanation is given of the route guidance subsystem and its guidance algorithm, which is based on the results of computer simulation. This report also discusses the effects that might be expected from introducing the CAC system in an area of Tokyo that contains 1500 intersections. In particular, this report closely scrutinizes the important route guidance subsystem, providing a quantitative analysis of the possibilities for easing congestion and achieving various other effects. A general review is made of the cost and benefits of such a system.
