干线公路与城市道路衔接段规划及设计要点研究

Research on the Planning and Design Points of the Connection Section Between Trunk Highways and Urban Roads

随着我国城镇化的快速发展,干线公路邻近城市主城区路段越来越多地承担城市交通功能,变为城市内部或环线道路,公路与城市道路衔接现象越来越普遍,但支持和指导衔接段合理设计的标准和方法不完善,常导致交通拥堵。要想实现城市内外交通顺畅,需更有效、合理地衔接干线公路与城市道路。文章主要通过对现有标准和以往经验的分析,从规划及设计两阶段形成系统的研究结论,研究结果可为干线公路与城市道路科学衔接提供理论支持和方法指导。

With the rapid development of urbanization in China,the sections of trunk highways near the main urban areas of cities are increasingly assuming urban traffic functions,becoming urban internal or ring roads.The connection between highways and urban roads is becoming more and more common,but the standards and methods for supporting and guiding the rational design of the connection section are not perfect,which often leads to traffic congestion.In order to achieve smooth traffic inside and outside the city,it is urgent to solve the problem of more effective and reasonable connection between trunk highways and urban roads.Through the analysis of existing standards and past experience,this paper forms a systematic research conclusion from the two stages of planning and design.The research results can provide theoretical support and methodological guidance for the scientific connection between trunk highways and urban roads.
