城市道路互通立交优化设计研究——以广州市某城市道路工程为例

Research on Optimization Design of Urban Road Interchange——Taking a Urban Road Project in Guangzhou as an Example

在城市主干路、快速路的交通设计中,经常选取互通立交结构来满足城市日益增加的交通量需求。考虑到城市用地的有限性,如何科学合理地进行互通立交设计已经成为设计单位的关注焦点。文章基于广州市某城市道路工程,对立交路段交通量进行预测,并且针对两种互通立交设计方案开展模糊综合评价分析,以便为相关工程设计提供理论参考依据。

In the traffic design of urban trunk roads and expressways,the interchange structure is often selected to meet the increasing traffic demand of the city.Considering the limitation of urban land,how to design interchange scientifically and reasonably has become the focus of the design unit.Based on a urban road project in Guangzhou,this paper predicts the traffic volume of the interchange section,and carries out a fuzzy comprehensive evaluation analysis on two kinds of interchange design schemes,so as to provide theoretical references for the relevant engineering design.
