摘　　要：常规的交通信号相位配时方法未考虑高峰时段的交通状态,导致控制效果较差。本文设计了一种基于云边协同的城市轨道交通信号相位配时方法提取冲突元素,合理组合非冲突相位,避免拥堵和碰撞。通过设置时间、交通流量和性能指标参数,利用云边协同框架处理数据,确保其准确性。协调主预信号,设置停车线距离,满足控制需求。仿真结果表明,该方法的相位配时控制效果较好,能够应用于实际作业。The conventional traffic signal phase timing method does not consider the traffic state during peak hours,resulting in poor control effectiveness.This article proposes a phase timing method for urban rail transit signals based on cloud edge collaboration,which extracts conflicting elements,combines non conflicting phases reasonably,and avoids congestion and collisions.By setting parameters for time,traffic flow,and performance indicators,and utilizing a cloud edge collaborative framework to process data,accuracy is ensured.Coordinate the main pre signal,set the distance of the parking line,and meet the control requirements.The simulation results show that the phase timing control effect of this method is good and can be applied to practical operations.
