Signal timing optimization at urban intersections is an important means to improve the traffic efficiency of urban areas. Through reasonable adjustment of signal timing, it can effectively reduce traffic congestion, improve the utilization rate of roads, and optimize traffic flow. This paper analyzes the influencing factors of signal timing optimization at urban intersections and discusses the role of different timing schemes on traffic smoothness. Scientific signal timing optimization not only helps to improve traffic efficiency but also reduces energy consumption and environmental pollution. This paper proposes a signal timing optimization method based on traffic flow and the characteristics of intersections, providing useful ideas for achieving efficient operation of urban traffic.
