伦敦立体交通对大西安战略规划的启示

Enlightment of London three-dimensional transportation on the transportation strategic planning of the greater Xi'an

为解决大西安交通发展与城市空间结构优化的问题,梳理伦敦立体交通的构建过程,总结了伦敦交通对城市空间形态的作用机理,并运用Roxy指数模型分析了大西安城市空间形态演化发展的趋势,对大西安交通战略规划提出了发展方向。分析认为:建立一体化的立体交通格局是大西安城市综合交通发展的必经之路,也是实现城市空间结构优化调整的必要手段。

In order to solve the problem between the transportation development and urban spatial structure optimization in Xi＇an, the paper, through analysis for the development of London three-dimen- sional transportation pattern, summaries the mechanism between urban transport and urban spatial of Lon- don. The author used the Roxy index model to analyze the trend of the evolution and development of Xi＇an urban spatial form, and proposed the guidance for the transportation planning. The study concludes that the establishment of an integrated three-dimensional transportation system is the only way to the compre- hensive urban transportation development of Xi＇an, and it is also the necessary means to achieve optimal adjustment of urban spatial structure.
