Abstract
The article transport vehicles are equipped with wireless tags that transmit tag information, and an article transport facility includes: a transport control apparatus that controls the entrance of the vehicles into the control area such that the number of vehicles that are present in one control area is no greater than a control number; a plurality of access points; and a position detection apparatus that detects the respective positions of the vehicles with an accuracy with which a plurality of positions in the control area are distinguishable, based on the same tag information that has been received by the access points. The transport control apparatus permits a number of vehicles, the number being greater than the control number, to enter the control area if a predetermined permission condition is satisfied, based on the positional information that indicates the position of each vehicle.
