Claim 8:
9. An article transport facility comprising:
a plurality of article transport vehicles configured to travel along a specified travelable route and transport articles; and
a controller configured to control the article transport vehicles,
the article transport vehicles comprising, as operation states, a first state of traveling toward a transport destination that is a destination set for receiving an article or delivering an article, and a second state in which the transport destination has not been set,
wherein the controller divides an entirety of the travelable route into a plurality of set areas and executes imbalance reduction control to arrange a standby transport vehicle such that imbalance of densities of standby transport vehicles present in the plurality of set areas is within a predetermined range,
wherein the standby transport vehicles are the article transport vehicles in the second state, and
wherein, in the imbalance reduction control, the controller performs density adjustment processing to cause a standby transport vehicle present in a high density area to move to another area, and the high density area is an area in which the density of standby transport vehicles is greater than or equal to a density of standby transport vehicles in the plurality of set areas.
