Abstract
A travelling path includes a first path and a second path that branches off from or merges with the first path at a connection position of the first path. A management area and a check area are provided for the first path. The management area includes a section from the connection position to a position that is at a first preset distance upstream of the connection position, and a section from the connection position to a position that is at a second preset distance downstream of the connection position. The check area includes a section from a preset position to a position that is at a fourth preset distance upstream of the preset position. In a state where an article transport vehicle that includes a control unit is located in the check area, the control unit determines whether or not the article transport vehicle is in a leading state where no other article transport vehicle is present forward of the article transport vehicle in the check area.
