壶柄式U形匝道在公路改扩建工程中的应用

The Application of Jug Handle U-shaped Ramp in Highway Reconstruction and Extension Projects

壶柄式U形匝道微循环作为一种交通组织方案,在平面交叉方案受限制的条件下能有效解决交通转换问题,但是作为一种非常规交通组织方式,其通行能力、位置选择以及布设形式等均需根据项目实际情况进行分析研究。主要对壶柄式U形匝道的布设形式、通行能力以及使用条件进行研究。

As a traffic organization plan, the jug handle U-shaped ramp microcirculation can effectively solve the traffic conversion under the condition of restriction on grade crossing scheme. But as an unconventional traffic organization method, its traffic capacity, site selection and layout type etc. require to be analyzed and studied according to the actual project condition. This paper mainly researched the layout type, traffic capacity and using conditions of jug handle U-shaped ramp.
