浅谈非典型城市互通形式选择

Brief Discussion on Selection of Atypical Urban Interchange Type

随着我国经济的迅速发展,汽车保有量迅速增加,道路交通压力日益增大,交通拥堵现象日益严重。为缓解交通阻塞问题,提高道路交叉节点通行能力,满足居民日常出行需求,互通立交已成为城市中必不可少的组成部分。但是,城市互通立交的建设条件和交通组成复杂,功能要求全面,立交形式的选择关系重大,因此,以柳江县兴柳路三期延长线工程中的柳石路互通立交为实例,总结城市非典型(畸形)交叉口设置互通立交的一些思路,希望能为相关工程提供借鉴。

With the rapid development of the economy and the fast increase of car ownership in China, the pressure of road traffic is increasing day by day and the traffic congestion is becoming more and more serious. In order to ease the traffic congestion, to improve the traffic capacity of road intersecting node and to meet the daily travelling demand of the residents, the interchange has become the essential component in a city. But the construction conditions and traffic composition of urban interchange are complicated,and the functional requirements are comprehensive. It is very important to select the type of interchange.Therefore, taking Liushi Road Interchange in Liujiang County Xingliu Road Phase Ⅲ Extension Line Project as an example, some ideas of interchange set up at an urban atypical(abnormal) intersection are summarized, which hopes to provide the reference for the relevant projects.
