OUTLINE OF THE COMPREHENSIVE AUTOMOBILE TRAFFIC CONTROL PILOT TEST SYSTEM

In the final phase of the Comprehensive Automobile Traffic Control Project, a pilot system was constructed and put into operation in October 1977. In the pilot area, which covers 28 sq km in southwestern Tokyo, a two-way exchange of digital information occurs between instrumented vehicles and roadside equipment. The driver receives a visual display of routing information that is based on current traffic conditions and other information for safe driving. In order to provide the drivers of noninstrumented vehicles with the routing information, new roadside displays were developed. A roadside radio system, which gives the driver traffic information and provides instructions in an emergency, was also developed. This paper presents an overview of the pilot system and describes the procedure of optimum route finding, the specification of the digital communication link between road and vehicle, and the hardware features of the principal equipment. A preliminary evaluation of the system performance is also described. (Author)
