Abstract
A travel route of a transport facility includes a guide zone in which a guide rail is disposed and a non-guide zone in which the guide rail is not disposed. A control system causes a guide drive section to execute a confirmation operation to drive a first guided section in a width direction Y in response to occurrence of a specific event in which a transport vehicle loses information on a travel position thereof, determines that the transport vehicle is in the non-guide zone in response to the first guided section moving from a first position to a second position or from the second position to the first position, and determines that the transport vehicle is in the guide zone in response to the first guided section being prevented from moving from the first position to the second position or from the second position to the first position.
