ROAD-VEHICLE COMMUNICATION SYSTEM AND VEHICLE-MOUNTED DEVICE

摘要

A road-vehicle communication system comprises road-installed radio devices, a center device, and a vehicle-mounted device mounted in a vehicle. The road-installed radio devices are each given identification information for identifying itself. The center device transmits to the vehicle the identification information about a first road-installed radio device installed on the road where the vehicle is traveling as first identification information via the first road-installed radio device and the identification information about a second road-installed radio device via which the vehicle is expected to travel to the destination as second identification information when the vehicle is traveling in the lane of the road where the first road-installed radio device is installed. The vehicle-mounted device stores the transmitted first identification information. If the secondarily transmitted second identification information includes the stored first identification information, the vehicle-mounted device reproduces content information transmitted together with the second identification information. The vehicle-mounted device judges whether or not the content information is for the lane where the vehicle is traveling and reproduces the content information if so.
