Abstract
Abstract An information exchange system is capable of realizing useful information exchange both for the service provider located along the road and providing services and the vehicular driver, by effectively using limited communication capacity of the road-vehicle radio communication. The information exchange system has a vehicle-mounted unit and a road-side unit providing information to the vehicle-mounted unit using a road-vehicle radio communication. The vehicle-mounted unit includes receiving unit receiving information transmitted from the road-side unit through a radio communication and transferring unit transferring at least a part of a content of the received information to a vehicular occupant. The road-side unit including storage unit storing information to be transmitted to the vehicle-mounted unit and transmitting unit transmitting information to the vehicle-mounted unit through the radio communication. The storage means stores at least information relating to a service provider where a service is provided at the location thereof. The road-side unit also includes editing unit editing information stored in the storage means on the basis of a relative position between the service provider and a communication region of the transmitting means and generating an edited information to be transmitted from the transmitting means.
