徐州城东大道京福高速节点改造方案探讨

Discussion on Reconstruction of Beijing-Fuzhou Expressway Node of Chengdong Avenue in Xuzhou

徐州城东大道快速路是徐州市快速路网中东西向的一条重要射线,是城东片区交通性干道之一。京福高速节点位于整个工程的中间偏东位置,其串联着京沪高铁徐州东站、城东大道快速路以及京福高速等重要的交通集散系统,交通功能极其重要。现状京福高速节点为双喇叭互通立交,只服务于城东大道地面道路,随着城东大道快速化以及徐州东站东广场扩建的逐步完善,节点交通服务能力需进一步提升与完善,改造难度大。基于徐州东站东广场总体交通组织,对节点改造提出了三种方案并分析了优缺点,通过对这种典型案例的分析,总结了城市快速路与高速公路及高铁站相互沟通的设计要点。

Chengdong Avenue Expressway in Xuzhou is an important ray of the east-west direction in the expressway network of Xuzhou and is one of the traffic trunks in the eastern part of the city.The node of Beijing-Fuzhou Expressway is located in the middle east of the whole project.It is an important traffic distribution system of connecting Xuzhou Railway Station(E)of Beijing-Shanghai High-speed Railway,Chengdong Avenue Expressway and Beijing-Fuzhou Expressway.Its traffic function is extremely important.The current node of Beijing-Fuzhou Expressway is a two-speaker interchange,which only serves the ground road of Chengdong Avenue.With the expressway of Chengdong Avenue and the gradual improvement of the east square extension of Xuzhou Railway Station(E),the node transportation service capacity needs to be further improved and perfected.But its reconstruction is great difficult.Based on the overall traffic organization of the east square of Xuzhou Railway Station(E),this paper proposes three schemes of node reconstruction and analyzes the advantages and disadvantages.Through the analysis of this typical case,this paper summarizes the design essentials of the intercommunication of urban expressway with expressway and high-speed rail station.
