Abstract
A plurality of roadside wireless devices are provided on a roadside of an entry of a toll area. A first roadside wireless device, which communicates with a vehicle-mounted device over wireless communication, sends unique information obtained from the vehicle-mounted device to a second roadside wireless device located, downstream to the first roadside wireless device, along a moving direction of the vehicle. The second roadside wireless device checks if unique information on the vehicle-mounted device obtained from the vehicle-mounted device matches the unique information on vehicle-mounted device notified from the first roadside wireless device to judge if the moving direction is a direction of entry into a toll area and charges the vehicle-mounted device for toll only when it is judged that the moving direction is the direction of entry into the toll area.
