Coordinated Optimization Control of Regional Traffic Signals Based on Vehicle Average Delay Model

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.
