<p><P>PROBLEM TO BE SOLVED: To provide a guided vehicle system by which traffic congestion conditions of traveling paths are appropriately understood and an overhead traveling vehicle can select an efficient traveling path. <P>SOLUTION: When blocking requests to a specific area are accepted from the overhead traveling vehicle, each zone controller adds them to queuing, gives blocking permission to a overhead traveling vehicle at the head of the queuing and when the traveling is completed, releases blocking. A time average is calculated using the number of overhead traveling vehicles in the queuing as an index indicating the traffic congestion circumstances of the specific area and announced from the controller to the overhead traveling vehicles. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
