城市准快速路规划设计关键技术初探——以苏州相城漕湖大道为例

Preliminary Study on Key Technologies of Urban Quasi Expressway Planning and Design for Caohu Avenue in Suzhou

摘要:

准快速路介于快速路与主干路之间，在主线重要的交叉口采用分离式立交，次要交叉口则采用右进右出，从而保证主线基本连续及其快速通行能力。准快速路能够充分发挥快速路连续通行的优点，且造价较快速路低，是交通强化的主干路，也是快速路的有效补充。依托苏州相城漕湖大道这一准快速路的设计实例，从速度选取、横断面布置、节点交通组织、人行过街设施设计、公交站台设计、近远期结合等方面对准快速路设计的关键技术进行了分析，以期为准快速路设计提供有益的参考。

Abstract:

The quasi expressway is between the expressway and the trunk road. The separated interchange is used at its important intersections of the main line, and the ring-in and right-out mode is used at its secondary intersections so as to ensure the basic continuity of the main line and its rapid traffic capacity. The quasi expressway can fully play the advantages of continuous traffic of expressway, and its cost is lower than the expressway, which is the main road of traffic enhancement and is also the effective supplement to expressway. Relying on the design case of the quasi expressway for Caohu Avenue in Xiangcheng District of Suzhou, the key technologies in the design of quasi expressway are analyzed from the aspects of speed selection, cross section layout, node traffic organization, pedestrian crossing facilities design, bus platform design, short and long term combination in order to provide the useful reference for the design of quasi expressway.
