摘　　要：文章提出在交叉口出口道设置可变车道的交通组织方法。首先,对城市道路交叉口出口道可变车道进行定义,明确潮汐进口道设置的约束条件;其次,确定潮汐进口道设置的车道数、车道长度、车道开闭时间等设置参数;然后,对设置潮汐进口道的交叉口进行信号控制研究,并通过实例仿真进行效果验证。仿真结果表明,设置潮汐进口道比未设置前道路交叉口的交通运行状况有显著提升,在一个信号周期内,直行交通量增加48%,停车线后最大排队长度缩短37%,交叉口车辆平均延误减少21%。To fin-tiler tap the potential of the road, full use of the road resources and alleviate traffic conges- tion. Set reversible exit lanes at the intersection. The paper first presents the definition of reversible exit lanes at intersections, and points out constraints of set reversible exit lanes; Secondly Determine the design parameters of reversible lanes, including the number of lanes, length and time of utilization; Then, re- search on the signal control of reversible lanes, and examples of validation measures. Simulation data fur- ther shows that traffic conditions have significantly improved by set reversible exit lanes, 48% increase of Straight volume, 37% reduction of the maximum queue length at the stop line, and intersections 21% re- duction in average vehicle delay within one signal period.
