摘要
平面交叉口是城市交通各种冲突的交汇点,亦是城市交通瓶颈之所在。传统平面交叉口通行能力存在上限,要求要跳出传统优化改善思路的窠臼,在交叉口设计方法和形式上做出改变。基于交叉口冲突理论,通过分离冲突、简化相位,进而提出位移型两相位交叉口的概念,并以T型交叉口为例,探索了位移型两相位T型交叉口的基本分类和各种形式。结果表明:基于冲突点位移数量和位置差异,位移型两相位T型交叉口可分为单点位移、两点位移、三点位移共3大类7种基本形式。本文成果可为平面交叉口优化设计提供一定的借鉴与参考。
The plane intersection is not only the intersection of various conflicts in urban traffic,but also the bottleneck of urban traffic.There is an upper limit to the traffic capacity of traditional plane intersection,which requires jumping out of the traditional optimization and improvement ideas and making changes in the design methods and forms of intersection.Based on the intersection conflict theory,the concept of displacement two-phase intersection is proposed by separating conflict and simplifying phase,and the basic classification and various forms of displacement two-phase T-intersection are explored by taking T-intersection as an example.The results show that,based on the number and position difference of the displacement of the collision point,the displacement-type two-phase T-intersection can be divided into 3 categories and 7 basic forms,including single-point displacement,two-point displacement and three-point displacement.The results can provide some references for the optimal design of plane intersection.
