摘　　要：为验证禁左远引掉头方案的改善效果,文章以南宁市鲁班路与大学东路交叉口为例,运用定量计算与仿真分析相结合的方法,利用VISSIM仿真软件,依据采用远引掉头前后的仿真结果。利用主道上的中央分隔带将次路上的左转车流进行车流远引,实行远引掉头相比现状信号配时排队长度大幅度缩短,交叉口信号周期长度由194 s缩短至84 s,车辆平均延误降低24.69%,平均排队长度缩短了47.61%,效果改善较明显,说明远引掉头对平面交叉口优化设计具有较好的实用价值,可有效减少延误,提高运行效率。In order to verify the improvement effect of the remote turn-around prohibition scheme,this paper takes Luban Road and University East Road in Nanning City as an example,adopts the method of quantitative calculation and simulation analysis,and uses the VISSIM simulation software,based on the simulation results before and after the remote turn-around.By using the central divider on the main road,the remote turn-around traffic on the secondary road was diverted far away.Compared with the current signal timing,the queue length of the remote turn-around was significantly reduced.The signal cycle length of the intersection was shortened from 194 s to 84 s,the average delay of vehicles was reduced by 24.69%,and the average queue length was reduced by 47.61%.The effect improved obviously.It shows that the remote turn-around has good practical value to the optimal design of the plane intersection,which can effectively reduce the delay and improve the operation efficiency.
