PURPOSE:To attain the traffic control for many trucks with complicated driving routes by setting an interference area where the interference occurs among driving routes of each truck and driving these trucks one by one through said interference area. CONSTITUTION:When a truck 3a detects the positions corresponding to the entrance and exit of an area, the truck 3a transmits these position signals and the code of the truck 3a itself to an area control station. The area control center decides the interference areas (e, g and h) based on the storage of the driving route of another truck 3b which is driven in the same area. Then the control station sets incoming positions Q1 and Q2 as well as passing positions P1 and P2 of both trucks 3a and 3b in said interference areas. The truck 3a detects the position Q1 is its driving course and transmits it to the area control station. Receiving the position Q1 of the truck 3a, the control station gives a drive command to the truck 3a as long as it does not receive the position Q2 of the truck 3b yet. While the control station gives a drive inhibiting command to the truck 3b when the station confirms that the truck 3a continues its drive and the truck 3b reaches the position Q2.
