Signal control method for high density road grid in traffic rush hour

The invention provides a method for controlling signals in a high-density road network during traffic peak. According to the total of traffic flows in the high-density road network, the method collects basic data about the high-density road network, which includes traffic static data, traffic dynamic data, and decision-making data from a decision maker, wherein, both the traffic static data and the decision-making data from the decision maker are classified as static data which is acquired from a static database of the high-density road network; the traffic dynamic data is classified as dynamic data which is gathered through traffic flow detection equipment; and a signal control scheme characterized by relatively long green light time length and red light time length is generated and applied to all signal intersections within the high-density road network. By controlling the total of the traffic flows within the high-density road network and realizing coordination among the intersections, the invention achieves the effects of improving the circulation efficiency of the traffic flows at all the intersections within the high-density road network during the traffic peak and reducing delays at the intersections for vehicles, thereby realizing efficient operation of the high-density road network.
