摘　　要：运用交通波理论,对逆向左转可变车道交通组织方式的运行原理、设置前提、适用极限进行分析,分别建立逆向左转可变车道设置最低交通量、适应最小交通量、适应最大交通量的计算公式.以实例计算和VISSIM仿真分析对适应交通量范围进行验证.研究表明,当左转交通量介于适应最小交通量与适应最大交通量之间时,设置后的左转车辆运行效果改善较为明显,实例计算值与仿真结果误差较小,表明研究具有一定合理性,可作为逆向左转可变车道设置的交通量判断依据.Using the theory of traffic waves,this paper analyzes the operating principle,setting premises and applicable limits of the reverse left-turn variable lane traffic organization method,and establishes the reverse left-turn variable lane to set minimum traffic volume,and adapt to maximum traffic volume.The example calculation and VISSIM simulation analysis are used to verify the adaptable traffic range.The results show that when the left-turn traffic volume is between the minimum traffic volume and the maximum traffic volume,the operation effect of the left-turn vehicle after the setting is improved significantly,and the error between the calculated value of the example and the simulation result is small,indicating that the conclusion of the study is reasonable and can be used as the basis for determining the traffic volume of the left-turning variable lane setting.
