Abstract
First and second roadside apparatuses for short-range communication with a vehicle-mounted device mounted in a vehicle are disposed upstream and downstream of a one-way road. The first and second roadside apparatuses installed on the road acquire vehicle identification information for identifying the vehicle when the vehicle passes through the communicative areas thereof. A administration device capable of communicating with the first and second roadside apparatuses stores the vehicle identification information acquired by the first roadside apparatus in a storage unit. If the vehicle identification information acquired by the second roadside apparatus is not included in the vehicle identification information stored in the storage unit, the administration device provides the vehicle with a reverse-way driving warning information through the second roadside apparatus. Thus, the road-vehicle communication system for warning a vehicle being driven or fully expected to be driven in the reverse-way on a one-way road such as a toll road against the reverse-way driving.
