摘　　要：在城市交通系统中,平面交叉口是道路网的重要枢纽点,但同时也是拥堵和事故的多发点。而T型交叉口是城市道路交叉口中常见的一种类型,所以T型交叉口设计要素的分析研究对缓解城市道路拥堵、减少交通事故以及改善城市形象具有重要意义。从渠化设计、交通组织、竖向设计等方面分析了城市道路T型交叉口在工程实践中的设计要素,总结了城市道路T型交叉口的设计方法,并结合具体工程实例进行实践,取得了良好的效果。In the urban traffic system,grade intersections are the important hubs of the road network,but are also the congestion and accident-prone points.T-shaped intersections are a common type of urban road intersections.Therefore,the analysis and research on the design elements of T-shaped intersections are of great significance to alleviating urban road congestion,reducing traffic accidents and improving city image.The design elements of urban road T-shaped intersections in engineering practice are analyzed and the design methods of urban road T-shaped intersections are summarized from the aspects of channelization design,traffic organization and vertical design.Combined with the specific engineering examples for the practice,a good effect is obtained.
