厦门市嘉禾路与海堤路节点改造方案研究

Study on Node Reconstruction Scheme of Jiahe Road and Haidi Road in Xiamen

为缓解厦门市嘉禾路与海堤路、高崎北三路交叉节点拥堵严重现状,提高作为厦门大桥南接线的嘉禾路通行能力,通过分析论证厦门市本岛进出通道流量、厦门大桥交通特征以及该节点拥堵成因,提出了该节点的改造方案。改造后,该节点的通行能力和集散能力显著提高,可满足厦门岛内外不断增长的对外交通需求。

In order to alleviate the severe congestion at the intersecting node of Jiahe Road,Haidi Road and Gaoqi North Third Road in Xiamen and improve the traffic capacity of Jiahe Road as the south connection of Xiamen Bridge,the traffic flow of in/out channel in Xiamen,the traffic characteristics of Xiamen Bridge and the causes of congestion at this node are analyzed and demonstrated.The reconstruction scheme of this node is put forward.After reconstruction,the traffic capacity and the collecting and distributing capacity of this node are improved significantly.This can meet the increasing demand for the external traffic inside and outside Xiamen.
