TRAFFIC CONTROL SYSTEM

A traffic control system includes a vehicle control apparatus and a traffic control apparatus. The vehicle control apparatus includes a travel environment data transmission unit and a travel control unit. The traffic control apparatus includes a data supplementability determination unit and a data supplementation unit. The data supplementability determination unit determines whether or not data regarding a communication-disrupted vehicle out of a plurality of vehicles is supplementable on the basis of travel environment data received from a nearby vehicle traveling near the communication-disrupted vehicle. The data supplementation unit generates traffic environment data supplemented with the data regarding the communication-disrupted vehicle, on the basis of the travel environment data received from the nearby vehicle, and transmits the traffic environment data generated, to the nearby vehicle.
