摘要： A position measurement portion manages a measurement target area by dividing the area into a plurality of section areas, and also manages, or keeps track of, an intra-area interfering object number which is the number of interfering objects in a given section area, independently for each of the plurality of the section areas. The travel controller determines, independently for each of the plurality of section areas, if the section area is in a congested state in which the intra-area interfering object number is greater than a set upper limit number, and selects a congested area travel mode as the travel mode when the travel controller is about to cause the vehicle to travel in a section area that is determined to be in the congested state.

摘要： Disclosed is an article transport facility in which interference between an article transport vehicle and an interfering object is prevented. A position detector is provided on the ground side for detecting the position of an interfering object, and an external managing device issues a deceleration command to the article transport vehicle if the distance from the article transport vehicle to the interfering object becomes less than or equal to a predetermined low speed distance, based on position information for the interfering object and travel position information for the article transport vehicle. A vehicle side travel controller changes a target travel speed from a normal travel speed to a reduced travel speed which is lower, or less, than the normal travel speed while the target travel speed is set to the normal travel speed, if the deceleration command is issued from the external managing device.
