摘　　要：交叉口是城市道路交通汇集区和疏散区,在城市道路的发展中起着重要作用。随着城市化进程的推进和汽车保有量的不断增长,平面交叉口已不能满足交通流的需求,严重影响道路的通行能力,造成交通拥堵。针对该现象,文章对平面交叉口进行了优化设计研究,分析了有无信号灯情况下交叉口机动车和非机动车的运行特性,并进行了交叉口的渠化设计,结果表明,渠化措施应相互配合,对不同的交通流应起到促进运行的作用。Intersection is the urban road traffic gathering area and evacuation area,which plays an important role in the development of urban roads.With the advancement of urbanization and the continuous growth of car ownership,grade intersections can no longer meet the needs of traffic flow,seriously affecting the traffic capacity of roads and causing traffic congestion.In view of this phenomenon,this paper studies the optimization design of grade intersections,analyzes the operating characteristics of motor vehicles and non-motor vehicles at intersections with or without traffic lights,and carries out the channelization design of intersections.The results show that the channelization measures should cooperate with each other and play a role in promoting the operation of diff erent traffic fl ows.
