四路交叉口左转专用信号配时改进方法研究

摘要

According to analyze the characteristic of left-turn traffic volume at 4-lagged intersection,construct the traffic signal model with left-turn phase for 4-lagged intersection,then optimal improvements strategy is introduced,at last,traffic signal improvement for left-turn phase at 4-lagged intersection is used with the tested intersection of Shaoxing city.%通过分析机动车左转车流在四路交叉口中的交通流特性，从交叉口左转车流运行特征出发，构建了交叉口左转专用相位信号配时模型，并在此基础上提出改进策略，结合绍兴市交叉口实际案例，阐述了该方法的应用情况。
