摘　　要：随着城市化进程的不断推进,交通拥堵问题成为影响城市居民生活和企业运营的主要挑战之一。文章旨在通过优化城市交叉口红绿灯时序,改善城市交通拥堵状况,提高交通流畅性和安全性。红绿灯作为交通控制的关键因素,其时序规划的合理性直接关系到城市交通系统的运行效率。为了应对城市交通的复杂性和多样性,文章构建了一个综合考虑机动车、行人和非机动车等多种交通参与者的微观交通仿真模型,通过数学公式和遗传算法进行优化,旨在找到最佳的红绿灯时序配置,以实现交通系统的最优化。文章的仿真实验选取了城市实际交叉口为案例,通过调整红绿灯时序观察交通流的变化,验证了模型和算法的有效性。通过研究发现,优化红绿灯时序不仅能够改善交通拥堵问题,提高交通流畅性,还能保障行人及非机动车的交通安全,这为未来城市的可持续发展和居民的出行提供了有益的参考和指导。With the continuous advancement of urbanization,traffic congestion has become one of the main challenges affecting the lives of urban residents and business operations.The aim of this study is to improve urban traffic congestion,traffic smoothness,and safety by optimizing the timing of traffic lights at urban intersections.As a key factor in traffic control,the rationality of the timing planning of traffic lights directly affects the operational efficiency of urban transportation systems.In order to address the complexity and diversity of urban traffic,this paper constructs a micro traffic simulation model that comprehensively considers various traffic participants such as motor vehicles,pedestrians,and non motor vehicles.Through mathematical formulas and genetic algorithms,the model is optimized to find the optimal timing configuration of traffic lights and achieve the optimization of the transportation system.The simulation experiment in this article selected an actual urban intersection as a case study,and verified the effectiveness of the model and algorithm by adjusting the timing of traffic lights to observe changes in traffic f low.Through research,it has been found that optimizing the timing of traffic lights can not only improve traffic congestion and smoothness,but also ensure the safety of pedestrians and non motorized vehicles.This provides useful reference and guidance for the sustainable development of cities and the travel of residents in the future.
