Abstract With the increasing number of motor vehicles, people pay more and more attention to the efficiency of travel and environmental problems. To solve this problem, an improved fast non dominated sorting genetic algorithm (NSGA-Ⅱ) is proposed and applied to the optimization of regional traffic signal timing. The algorithm is a multi-objective optimization algorithm, which takes the average delay and exhaust emissions of regional traffic as the optimization objectives. After the algorithm optimization, a series of optimal values will be obtained, from which the comprehensive optimal value is selected. Finally, VISSIM microscopic traffic simulation software is used to build a simulation model for this case, and the optimization results of the method are verified. The effectiveness of the proposed method is verified by comparing it with the improved fast non dominated sorting genetic algorithm. The simulation results show that the optimized timing reduces the CO emission by 8.213% and the average vehicle delay by 19.023%.
