Abstract: To allow a travelling vehicle to travel more smoothly, a host controller of a travelling vehicle system includes a first determination part which determines whether or not a second track selected by a first travelling vehicle is the same as a second track selected by a second travelling vehicle, and an entry permission issuing part that issues an entry permission into a switching track to the second vehicle after checking passage of the first vehicle through the switching track when the second track selected by the first vehicle is different from the second track selected by the second vehicle, and issues the entry permission into the switching track to the second vehicle regardless of receipt or non-receipt of the passage report from the first vehicle when the second track selected by the first vehicle is the same as the second track selected by the second vehicle.
