Abstract The present invention relates to the technical field of intelligent transportation control, in particular to an arterial street intersection signal coordination control optimization method based on NEMA phase. The invention analyzes the minimum clearance time of the arterial street traffic flow under the Lag-Lag phase structure in NEMA phase by using L-W theory (traffic wave theory) on the basis of the traffic OD (origin destination) data in the arterial street coordination control system, and determines the maximum green wave band in the arterial street direction at the intersections, so that the vehicles entering the arterial street of the green wave control system can pass within a green time, greatly reducing the average vehicle delay time in the system.
