ROAD COMMUNICATION SYSTEM AND MOVING BODY DEVICE

摘要

A moving body device (20) comprises moving body establishing means for establishing communication with a road device (40), detecting means for detecting vehicle information on a vehicle, moving body transmitting means for transmitting the detected vehicle information to the road device, moving body receiving means for receiving warning information transmitted from the road device depending on the transmitted vehicle information, and presenting means for presenting the received warning information. The road device (40) comprises road establishing means for establishing communication with the moving body device, road receiving means for receiving the vehicle information transmitted from the moving body device, acquiring means for acquiring road environment information, creating means for comparing the road environment information and the vehicle information and creating warning information as necessary, and road transmitting means for transmitting the warning information to the moving body device. Thus, a road communication system capable of reliably transmitting warning information to the driver even if the vehicle is traveling at high speed is provided.
