Abstract: The present invention prevents the interference of vehicles traveling on-coming to each other when a plurality of vehicles are traveling on-coming to each other on a traveling path with a predetermined road width without increase in cost caused by setting a wide course width and without a drop in work efficiency caused by decreasing velocity. If one of the vehicles detects the other vehicle by its obstacle detection means when the vehicles are traveling on-coming to each other, the vehicle which detects the other vehicle begins deceleration to stop itself. At the same time, this vehicle transmits a deceleration control command for stopping the other vehicle to the other vehicle via transmission/reception means, therefore the other vehicle starts deceleration even if this vehicle cannot detect an obstacle.
