Abstract
A travelling vehicle system includes an intermediate track; first tracks; second tracks; a first switching track which connects the intermediate track and one of the first tracks to an other one track; and a second switching track which connects the intermediate track and one of the second tracks to the other one track. When a travelling vehicle travels on the intermediate track, a travelling vehicle controller determines before the travelling vehicle enters the first switching track that the travelling vehicle can enter both the first and second switching tracks in the case of determining that the first track on which the travelling vehicle is currently travelling is connected to the intermediate track and determining that the intermediate track is connected to the second track selected by the travelling vehicle.
