A traveling vehicle (12) is self-propelled and docked in a quadrilateral docking area (20) having an entrance (55) on one side thereof, and includes: a docking point obtainment unit which obtains first to fourth points indicating positions of four corners of the docking area and represented in relative coordinates with respect to a position of the traveling vehicle (12) a reference distance detection unit (35) which obtains a reference distance indicating a distance between the traveling vehicle (12) and the docking area (20) and a movement control unit (33) which controls movement of the traveling vehicle (12) moving to the docking area (20), based on the first and second points when the reference distance Ls is not shorter than a first correction distance N1, and based on at least the third and fourth points when the reference distance Ls is shorter than the first correction distance N1. The first and second points are located on an entrance (55) side of the docking area, and the third and fourth points are located on a rear side.
