Abstract: In the coordination direction of oversaturated arterial road, this paper presents an objective function of the dynamic coordinated control model to maximize the number of through vehicle by introducing the queue management strategy weighting factor. The constraints of the model are analyzed from offset, green time of the coordination phase, queue management strategy and the traffic volume leaving the intersection in the coordination phase. Four different queue management strategies are put forward to describe their specific content and analyze their corresponding weight factor formulas in each strategy. Integrating the objective function and constraints, the dynamic coordinated control model is developed for oneway oversaturated arterial road. Finally, taking the Jihua Road in Foshan city of China as the case, the data from the VISSIM simulation shows that the model can effectively reduce the queue length and delay, and improve the capacity of the arterial road as well.
