城市快速路辅路功能定位分析及设计标准

该文结合我国城市快速路发展实际,分析了城市快速路辅路在规划设计层面的一些基本问题,提出快速路辅路基本职能分三种:服务职能、集散职能、通道职能。辅路因设置目的不同及所承担的任务不同,可划分为不同的类型,即标准服务型、集散型、服务-集散型、综合通道型。每一种类型又都具有各自不同的交通功能及选型条件,以及相应的设计标准和建设规模。该文还结合典型的案例进行了说明。

Analysis of Functional Orientation and Design Standard for Auxiliary Roads of Urban Expressway

Combined with the development practice of urban expressway in China, the article analyzes some basic problems of these auxiliary roads in the planning and design, and puts forward three basic functions-service function, distribution function and passage function of the auxiliary roads. The auxiliary roads can be divided into the different types, i.a standard service, distribution, service Shanghai-distribution, and integrated passage due to the different setup objectives and the different responsible tasks. Each type of auxiliary road has its own traffic function and selection condition as well as the relative design standard and construction scale. The article also illustrates the typical engineering cases.
