This invention reliably prevents interference between travelling vehicles in a curved section, and makes it possible for travelling vehicles to efficiently travel in a curved section. A ground controller in a travelling vehicle system stores travel permissions for a curved section that are given to travelling vehicles, and deletes the travel permissions when the travelling vehicles leave the curved section. When a request for a permission to travel in the curved section is received from a travelling vehicle, the ground controller references the memory, gives a first travel permission if a permission to travel has not been given to another travelling vehicle, and gives a low-order travel permission that permits travel with a lower speed than the first travel permission if a permission to travel has been given to another travelling vehicle. |
