TOD交通走廊形成机理分析及经验借鉴——以美国阿灵顿县R-B走廊为例

Analysis on the Forming Mechanism of TOD Traffic Corridor and Experience——Taking the R-B Corridor of Arlington County of USA as a Case

TOD(Transit-Oriented Development,公共交通为导向的城市土地开发)交通走廊是以大运量的客运走廊为载体,通过选择若干站点进行TOD模式的开发,突破传统的单个节点开发形式,充分发挥规模效应,形成整合优势。本文以华盛顿特区西南部的阿灵顿县(Arlington County)的Rosslyn-Ballston轴状走廊(下文简称R-B走廊)为例,从宏观、中观和微观三个层次分析其形成机理,总结出TOD交通走廊建设的成功经验。

TOD traffic corridor can support large passenger transport volume. Through choosing a number of sites for the exploration of TOD, we can break through a traditional form of noding, and fully display the effect of large scale, so, the integrated advantage will appear. Taking the Rosslyn-Ballston axle-shaped corridor of Arlington County （that is called R-B corridor for short in the following text） as a case, which locates in the south-west of Washington D.C., we analyzed the formation mechanisms of the corridor from different levels, and summarized the positive experience from the TOD traffic corridor constructing.
