Abstract

The development of a road/automobile communication system is discussed. An inductive radio system and a microwave system are potential candidates. The inductive radio system has four lanes*4 m of communication range with a bit error rate characteristic of 5*10/sup -5/ to 5*10/sup -6/ and a maximum data volume of 460 kb attainable at a beacon when an automobile is traveling at 100 km/h. The microwave system using the 2.5 GHz frequency band has five lanes*60 m of communication range and a maximum data volume of 400 kb with a transmission data rate of 512 kbps. By deploying the phase shift keying/reverse amplitude modulation method, the system was able to determine the position of automobiles very accurately and to detect their direction of motion. The microwave system has very high potential for future applications and will be implemented in Japan.<>
