- the following effects can be obtained. (1) Since the size of the blocking areas 20 and 30 is minimized, the number of overhead traveling vehicles 14 that can pass through the blocking areas 20 and 30 per unit time is increased, and the conveyance efficiency is improved. (2) Since the interference is avoided by the optical distance sensor 54 in the straight section, the processing is simple. (3) In the inter-vehicle distance control area in the curve section, branching section, or junction, inter-vehicle distance control is performed by intercepting the report of the position of the overhead traveling vehicle to the controller. For this reason, compared with the case where it communicates directly between the traveling vehicles 14, the communication amount of LAN50 can be reduced. (4) Since the overhead traveling vehicle entering the junction from the same side is given priority for blocking at the junction, the junction can be traveled more efficiently. In addition, although the overhead traveling vehicle 14 reports the position of the own vehicle to the ground-side controller 12 even in a straight section, it may be reported only in the inter-vehicle distance control areas 21 and 31.
