Abstract: In a traffic flow control system, communication is performed with a travel control device of a moving body passing through a transportation route and the traffic flow of the transportation route is controlled. The traffic control system includes an entry authority management unit and a communication unit. In a transportation route divided into virtual areas, the entry authority management unit manages entry authority for each area, managing tokens in a number that corresponds to the area, and guiding entry of the moving body to the area by attaching entry authority to a token and delivering the resulting token to the travel control device. The communication unit communicates the entry authority and tokens to the travel control device.
