The present invention provides an article transport facility. It is desirable to prevent the article transport vehicles from coming into contact with each other by properly detecting the position of each article transport vehicle even when the track along which a plurality of article transport vehicles travel include a curved section. A position detector (7) detects an absolute coordinate of an article transport vehicle (3) based on markers at a plurality of locations along a direction in which the track including a curved section extends, and at least provides position information including information on the absolute coordinate to other article transport vehicles (3), through a wireless network (50). A transport vehicle controller (5), configured to cause the article transport vehicle (3) to travel at least from a transport origin for an article to a transport destination, based on a command from a managing controller (1), causes a travel speed of the article transport vehicle (3) tobe reduced based on position information of the corresponding one of the article transport vehicles and position information of another of the plurality of article transport vehicles, if a separationdistance between the corresponding one of the article transport vehicles and the another of the plurality of article transport vehicles is less than, or equal to, a set separation distance specifiedin advance.
