城市快速路交通组织及其与路网的关系探讨——以福州市南二环路的建设与改造为例

An Investigation on Traffic Organization of Urban Expressway and Its Relevance with Road Network——Taking the Construction and Reconstruction of South Second Ring Road in Fuzhou as an Example

城市快速路设计的关键内容是交通组织设计,即快速路(主路)交通与周边路网机动车交通接驳关系的处理。快速路通过互通立交匝道、出入口及辅路与被交道路实现交通接驳,不同的接驳方式其便利性和通行能力也各不相同。本文以福州市南二环路的建设和改造为例,探讨如何对快速路沿线各道路接驳方式进行适当安排,合理配置交通资源,以实现路网的最佳效益。

Traffic organization is crucial in the design of urban expressway,i.e.,the management of traffic connection between expressway(main road)and surrounding road network.The connection is achieved by ramp of interchange,entrance and exit,and relief road between expressway and intersection roads,leading to different degree of convenience and traffic capacity.Taking the construction and reconstruction of South Second Ring Road in Fuzhou as an example,this article investigated how to arrange the traffic connection between expressway and the roads properly and configure the resources possibly,to reach the optimal benefits of the road network.
