摘　　要：平面交叉口作为交通流的集散地,直接影响城市道路的运行效果,由于近些年我国汽车保有量的大幅度提升,导致原有的平面交叉口设计逐渐无法满足交通需要。为此,文章将结合现有的城市交通状况,阐述道路平面交叉口的优化设计方法,包括交通渠化设计,机动车道、非机动车道渠化设计,并提出基于多目标优化模型,改进信号控制设计。最终根据交叉口饱和度、延误等指标,评价平面交叉口设计效果,以此提高城市道路交叉口的通行能力。As a hub of traffic flow,level intersections directly affect the operational efficiency of urban roads.Due to the significant increase in the number of cars in China in recent years,the original design of level intersections is gradually unable to meet traffic needs.Therefore,this article will combine the existing urban traffic conditions to elaborate on the optimization design methods of road level intersections,including traffic channelization design,motor vehicle lane and non motor vehicle lane channelization design,and propose a multi-objective optimization model to improve signal control design.Finally,based on indicators such as intersection saturation and delay,the design effect of level intersections is evaluated to improve the traffic capacity of urban road intersections.
