城市交通走廊分流措施与设计模式

针对我国大城市存在不同性质交通流对走廊核心干路过度依赖的问题，提出路网分流和断面分流两种交通走廊功能保障措施，分别以上海市杨高路交通走廊和库里蒂巴西南交通走廊为例，剖析以这两种保障措施为核心的交通走廊设计要点。对城市发展轴交通走廊提出三种设计模式，对一般性交通走廊提出两种设计模式，分别探讨了每种模式的适用条件、设置要素、优缺点和实施保障要求。

Diverging Traffic Flows and Design Patterns for Urban Corridors

With respect to the fact that different types of traffic excessively depends on core arterials of transportation corridors in big cities in China, this paper presents two measures to guarantee the function of transportation corridors, including diverging traffic flows through road network and segments. Based on these two measures, case studies from Shanghai Yanggao Rd. and southwest corridor in Curitiba are provided to discuss the design tips for transportation corridors. Then the paper presents 3 design patterns for urban axis corridors as well as 2 design patterns for common corridors, along with application conditions, arrangement factors, advantages and shortcomings, and implementation requirements for each pattern respectively.
