摘　　要：为改善南宁市民族金洲路口晚高峰长期拥堵状况,文章提出了通过禁左,将左转交通远引至相邻的民族滨湖路口和金湖环路回转,并在民族滨湖路口东进口道增设一条掉头专用车道的方案。通过采用微观交通仿真模型VISSIM对影响区域路段现状和远引掉头方案进行了模拟分析,结果表明,远引掉头后路网行程时间改善了近30%,民族金洲路口采取远引掉头是可行的方案。To improve the long-time evening peak-hour congestion situation at Naming Minzu-Jinzhou in- tersection,this article,through NO LEFT-TURN, proposed the program of leading the left-turn traffic to the adjacent Minzu-Binhuintemection and Jinhu Ring Road as well as adding a special U-tum lane at east entering road of Minzu-Binhu intemection.Thugh the microscopic traffic simulation model VIS- SIM,it conducted the simulation analysis on current affected road status and U-turn lead program,and the results showed that the travel time of road network is improved by nearly 30 percent after U-turn lead,thus using the U-turn lead at Mirzu-Jinzhou intersection is a feasible program.
