Disclosed is a roadside-to-vehicle communication system which allows a vehicle, which is traveling within a roadside-to-vehicle communication area, to receive signal information from a roadside device multiple times. The roadside-to-vehicle communication system includes determination means for determining whether or not new information is added to the signal information transmitted from the roadside device, and update means for, only when the determination means determines that the new information is added to the signal information, updating the signal information which is used on the vehicle side. With this configuration, it is possible to reduce the processing load on the signal information even when the signal information is received multiple times through roadside-to-vehicle communication. |
