In order to improve the effect of green wave coordination control on urban arterials, this paper proposes an arterial green wave coordination control method based on signal phase optimization at intersections. The method uses Webster's signal cycle algorithm to increase the adjustment zone of phase difference between adjacent intersections on the arterial by optimizing the signal phase composition of each intersection on the arterial; and uses the number solution method to determine the phase difference between adjacent intersections, and then determines the arterial coordination control scheme. The case analysis shows that the optimization scheme effectively improves the vehicle delay time, the number of vehicles in queue, and the number of stops.
