Passing through the upstream point P on the road Rp during the time t1p to t3p of one signal period Tp in order to arrive at and pass through the intersection A during the green light period t2a to t3a on the road Rp side of the intersection A where the roads Rp and Rq intersect The number of vehicles passing through the point P between times t1p and t2q among the vehicles heading for the intersection A is counted, and the occurrence of traffic jam between the point P and the intersection A is predicted from the counted result, and the degree of the predicted traffic jam The traffic control method adapted to the “intersection non-stop driving control system” characterized in that the green light extinction time t3a in the road Rp side green light period t2a to t3a of the intersection A is variably controlled by .
However, at the time t2q, the vehicle starts passing through the upstream point Q on the road Rq so as to pass the intersection A during the road Rq side green light period t3a to t4a continuing from the road Rp side green signal period t2a to t3a at the intersection A. It's time. In response to the traveling condition information for passing through the intersection A without stopping, the vehicle passing number counting at the point P is transmitted to the vehicle passing the point P from the point P roadside device toward the intersection A. The traffic control method according to claim 1, wherein the traffic control method is performed by counting the number of times of reception condition information reception recognition signals returned from the vehicle to the roadside device.
