In a guided vehicle system, articles are transported between load ports by a plurality of guided vehicles traveling with articles carried thereon along a predetermined traveling route. A guided vehicle system controller communicates with a superordinate controller and guided vehicles, and creates traveling schedules representing positions and times at which the guided vehicles travel, disregarding interferences with other guided vehicles. For both newly created traveling schedules and traveling schedules from which interferences have been eliminated, interferences between the guided vehicles are detected, and the traveling schedules of the guided vehicles is modified so as to eliminate the detected interferences. The traveling schedules from which interferences have been eliminated interferences is stored. Also, the positions of the guided vehicles are stored based on data received from the guided vehicles, and the traveling schedules is modified. |
