摘要
关键节点是公路市政化改造设计的重点所在。文章结合312国道无锡段关键节点的改造工程,从宏观的区位分析到微观的具体设计角度对关键节点的设计技术进行分析,将节点的改造分为交叉口的几何设计以及节点交通流的组织两部分组成,全面讨论了立交、渠化、管理与控制以及左转交通流组织等多方面的具体改造措施,对公路市政化改造中关键节点的设计要点和典型方案进行了总结。
The design of key nodes is important in municipal roads reconstruction. Combing with key nodes reconstruction engineering of Wuxi section in No.312 national highway, this paper summarizes the technical of key nodes design from the perspective of macro location analysis as well as microscopic specific design. Firstly, this key nodes design technology is summarized which divides nodes reconstruction into two parts： intersections geometric design as well as node traffic flow organization, and then specific measures are analyzed from aspects of grade separation, channelization, management and control as well as left-turn traffic flow, finally the design points and typical programs of key nodes in municipal roads reconstruction are summarized.
