Abstract: A determination section determines that a transport vehicle entered a curved zone from a straight zone based on a front-rear rotation speed difference between the rotation speed of a first rear wheel and a second rear wheel and the rotation speed of at least either a first or second front wheel. A measurement section measures a distance-to-curve, which is the distance that the transport vehicle travels from when a detector detects a detection target until when the determination section determines that the transport vehicle entered the curved zone from the straight zone. If the detector detects a curve ahead detection target while curve ahead information is stored in a storage section, a travel control section executes speed change control before or when the transport vehicle enters the curved zone.
