Abstract:

In order to seek an effective method of traffic coordination control for road networks,the traffic behaviorsat intersections are analyzed based on the macroscopic transmission model via a gridding procedure,and a newmacroscopic simulation model is constructed to fast evaluate control schemes.Then,by taking the optimal trafficrunning as the objective,a bi-level programming model for traffic coordination control is proposed.Moreover,bycombining the macroscopic simulation model with the proposed bi-level model,a method of traffic coordination controlbased on the improved macroscopic traffic model is presented.The method is finally tested on a virtual networkwith three different traffic demands,and the results are compared with those of the Transyt-7F method.It is foundthat the proposed method is feasible and is superior to the Transyt-7F method especially in the high demand scenario.

Key words: traffic control, macroscopic model, gridding, bi-level programming
