This paper addresses the challenging problem of coordinated control of regional road network traffic signals. By analyzing the dynamic characteristics of regional road network traffic flow, we propose a regional vehicle delay model and establish the objective function of minimizing the vehicle average delay. Considering the high-dimensional characteristics of the objective function, a chaos genetic optimization algorithm is proposed to improve the efficiency of global optimization. Finally, we implement the real-world road network micro-simulation experiment to demonstrate that our proposed delay model and coordinated optimization method can effectively improve the traffic efficiency of the regional road network.
