中文摘要：

在城市大力发展慢行交通的背景下,交叉口非机动车通行的秩序和效率成为发展非机动车交通影响交通效率的关键.针对城市道路大型交叉口存在的非机动车问题,进行了非机动车的干扰分析,总结非机动车在交叉口通行的管理策略,并从设置非机动车左转待转区的角度提出大型交叉口的优化策略.采用VISSIM软件进行了模拟仿真,结果表明优化策略对于改善大型交叉口的通行效率是有效的.

英文摘要：

Under the background of developing pedestrian and bicycle system in cities, the order and efficiency of non-motor vehicle is the factor influencing the traffic efficiency at the intersection. Based on the problems of bicycle system at intersections, the interferences are analysed, the management measures are summarized and the optimization strategy is put forward from the aspect of left-turn waiting area of non-motor vehicles. Two simulation experiments were implemented using Vissim, and the results show that the optimization strategy is effective for the traffic efficiency at large intersections.
