Abstract
A ground controller in a travelling vehicle system stores travel permissions for a curved section that are provided 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, provides a first travel permission if a permission to travel has not been provided to another travelling vehicle, and provides a low-order travel permission that permits travel with a lower speed than the first travel permission if a permission to travel has been provided to another travelling vehicle.
