A route-choice method based on zone traffic signal coordination control

Traditional green band was focused on straight lines. However, the origin and destination of the main traffic flow in the road network are usually diagonal. Apparently, a straight green band cannot meet the traffic demand in this case. Therefore, it is necessary to study green band with turnings in the zone traffic signal coordination control. This article focuses on the method which could compute the optimal route for an extra traffic flow of commuters and set the green band in a square area of 4*3 intersections, given the basic information of road conditions, traffic volume, split setting, etc. In the simulation, this article uses the data from Huilongguan area in Beijing. Using the Synchro to simulate the road network, it distributes the traffic flow of commuters into four routes respectively and gets the reports of network performance after simulation of each situation. The reports shows that the optimal route, which performs better in the measure of effectiveness, such as delay per vehicle, stops delay per vehicle, speed, fuel combustion efficiency, width of green band, bandwidth efficiency, is exactly consistent with the results calculated by Rout-Choice model.
