尤溪洲南桥头交通拥堵改善方案研究

Study on Improvement Scheme of Traffic Congestion at South Bridgehead of Youxizhou Bridge

尤溪洲大桥及南北引桥一直是福州城区常年拥堵的路段之一。以福州市尤溪洲大桥南桥头为例,从宏观路网功能与微观节点交织区两方面出发,对尤溪洲大南桥头交通改善方案进行研究,提出功能分流改善方案与合流区扩容方案,并利用交通宏观模型、微观模型进行仿真论证,通过综合比较选择最优方案。

For many years,Youxizhou Bridge,and its south and north bridge approaches are always one of the road sections with the traffic congestion in the urban area of Fuzhou.Taking the south bridgehead of Youxizhou Bridge in Fuzhou as an example,from the aspects of macroscopic road network function and micro node interweaving areas,the traffic improvement scheme of the south bridgehead of Youxizhou Bridge is studied.The functional separation improvement scheme and the combined area expansion scheme are proposed.The macro model and micro model of the traffic are used to carry out the simulation and demonstration.The optimal scheme is selected through the comprehensive comparison.
