龙东大道快速化在张江科学城段匝道布置方案研究

Study on Ramp Layout Scheme of Longdong Avenue Expressway in Section of Zhangjiang Science City

龙东大道位于上海市浦东新区,是城市内环线的东西向切线,目前为城市主干路,在上海市骨干路网规划中为城市快速路,拟于"十三五"期间完成快速化改造。根据龙东大道快速化总体布置方案,全线共设置8对匝道出入口,针对张江科学城段匝道位置的选择,从区域的总体发展、路网功能布局以及沿线交通需求等角度出发,通过设计方案比选分析,利用路网流量分析预测,论证推荐方案的合理性和科学性。

Longdong Avenue is located in Pudong New District of Shanghai, is an east-west tangent line of the urban inner ring line, is a main trunk highway of city now, will be an urban expressway in the framework road network planning of Shanghai, and is proposed to complete the expressway reconstruction in the "thirteenth five-year" period. Based on the overall layout scheme of Longdong Avenue Expressway, a total of eight pairs of ramp entrance and exit are set up along the line. Aiming at the selection of ramp locations in the section of Zhangjiang Science City, from the overall development of the area, starting from the function layout of road network and traffic demands along the line, according to the comparison and analysis of design schemes, and utilizing the traffic flow analysis and forecast of road network, this paper demonstrates therationality and scientificity of the recommended scheme.
