摘　　要：平面交叉是交通网络中极其重要的节点,同时也是交通事故频发的地点。平面交叉设计的合理与否,直接影响到道路的通行能力及行车的安全。通过工程设计实践经验以及具体工程实例,根据交通量计算确定各个方向车道数,进行交叉口渠化。Plane crossing is an extremely important node in traffic network and also a place where traffic accidents occur frequently.Whether the plane crossing design is reasonable or not has a direct impact on the capacity of the road and the safety of driving.Based on the practical experience of engineering design and concrete engineering examples,this paper determines the number of lanes in each direction according to the traffic volume calculation.

关 键 词：平交口 通行能力 渠化设计 道路交通
