国外城市道路交叉口设计

Intersection Design of Overseas Urban Road

城市道路交叉口设计在欧美国家非常受重视,而在我国则刚刚起步,我们需借鉴他人优秀成果来消化吸收,以提高自身水平。本文收集了大量国外交叉口设计成果,按不同服务功能对其进行分类,从城市简易立交、平面交叉口应用类型、交叉口的自行车道设计三个方面,分析了他们的特征和适用条件,重点介绍了快速路—主干路交叉口设计、沿河道路交叉口设计、平面交叉口的分类、环形交叉口的适用情况、支路—主干路渠化设计以及交叉口自行车道设计。文章最后总结了城市平面交叉口渠化设计要点,希望能够对我国的交叉口设计工作予以启示。

Intersection design of urban road is much concerned in Europe and the United States, but it has just started in China. We need to learn from the outstanding achievements of other countries for the intersection design in China and to improve our results. This paper collects a large number of foreign intersection design results, and classifies according to different services. The paper analyses characteristics and conditions of application of easy interchange, application type of intersection and bike lanes design in the intersection. The focus is on expressway-arterials intersection design, intersection design of urban roads along the river, application types of intersection, application of roundabouts, locals-arterials intersection channelization design and bike lanes design in the intersection. Finally, the elements of plane intersection channelization design are summarized, which hope to enlighten the work of the intersection design in China.
