Abstract
An area is set as an interference area, in which a transport vehicle is located in a state in which a portion of the transport vehicle overlaps a door trajectory which is a movement trajectory of a fire protection door. A control portion that controls a subject vehicle, which is a transport vehicle to be controlled, prohibits the whole subject vehicle from entering the interference area if it is determined, based on another-vehicle information, which is information of a traveling state of another vehicle that is different from the subject vehicle, and information regarding the interference area, that the interference area is present between the another vehicle located forward of the subject vehicle and the subject vehicle, and that a stoppable area is not secured between a rear end position of the another vehicle and the fire protection door.
