摘　　要：小锐角错位交叉口不仅在整体空间布局形态中存在大量安全隐患因素,还呈现出渠化技术难点多、要求高的特点。总结该类综合复杂路口交通安全设计经验,提出不同场景的改造思路:针对错位交叉口提出在2种不同情形下的交通安全设计思路;针对小锐角交口提出2种线形修正思路和1种原状态下优化思路。同时,以由拳路与湖桐线、由拳路与洛隆路交叉口改造为例进行分析,相关参数对比表明,改造后机动车、非机动车、行人守法率分别提升至98%、91%、92%以上,交叉口总延误降低23%,交叉口各方向有效通行能力得到不同程度提升,整治效果良好,为同类型交叉口交通安全设计提供参考。There are a lot of potential safety hazard factors and technical difficulties and high requirements in the sharp angle and dislocation intersection.This paper summarizes the experience of this kind of comprehensive complex intersection traffic safety design,and puts forward the transformation ideas of different scenarios.In view of the dislocation intersection,the traffic safety design ideas in two different situations are put forward.Two kinds of linear correction ideas and one optimization idea under the original state are proposed for the small sharp angle intersection.At the same time,taking the transformation of the intersection of Yuquan Road and Hutong Road,Yuquan Road and Luolong Road as an example,the comparison of relevant parameters shows that the compliance rates of motor vehicles,non motor vehicles and pedestrians are increased to more than 98%,91%and 92%respectively,the total delay at the intersection is reduced by 23%after the transformation.The effective traffic capacity in all directions of the intersection is improved to varying degrees,and the improvement effect is good,which provides a reference for the traffic safety design of the same type of the intersection.
