Abstract
A conventional V2X communication system relays vehicle information received from vehicles, from a base station to all vehicles in an area. Accordingly, a problem arises in that unnecessary transmission to vehicles which do not require vehicle information occurs, resulting in increase in a traffic amount in communication. According to the present disclosure, only if it is determined, based on information that is held by a vehicle or a base station and that is about an area in which direct transmission or reception is difficult, that direct transmission of vehicle information to another vehicle or reception of vehicle information transmitted from the other vehicle is difficult, the vehicle information is transmitted to the other vehicle via the base station.
