A navigation and communication system utilizing roadside beacons is under development. The functions and infrastructure of the Road/Automobile Communication System are outlined, the in-vehicle equipment is described and the results of field tests conducted in the Tokyo/Yokohama area are reported. The system provides the driver with such information as present location and traffic conditions, plots optimum and alternative routes to destination, and enables limited two-way communication to be made. Field testing indicates that the navigation and route-search functions are of great benefit to drivers in an unfamiliar area. However, route-search calculation time must be reduced, especially for route revision in response to incoming data.
