北京大院生活型街道边界要素对可步行性的影响--以玉渊潭南路、太平路、翠微路为例

The Influence of Boundary Elements on Walkability in Beijing Compound-Unit Livable Streets:A Case Study of Yuyuantan South Road,Taiping Road and Cuiwei Road

文章以提升城市街道可步行性为目标,以北京大院生活型街道为例,对街道边界空间要素对可步行性的影响进行了研究。研究分析了3条北京大院生活型案例街道的边界要素构成及组合模式,并基于街景图像对街道可步行性进行评分,将要素与可步行性评分进行相关性研究,指出对可步行性影响高的边界要素及其作用,为大院生活型街道的更新设计提供参考。研究表明,要素的数量、感知边界要素的类型、要素的细部设计对街道可步行性有较高影响。此外,绿地要素的灵活运用能够显著提升街道的可步行性。

With the goal of improving the walkability of urban streets,this study investigates the influence of street boundary space elements on walkability,taking Beijing Compound-Unit livable streets as examples.The study analyzes the boundary element composition and combination patterns of three Beijing Compound-Unit livable case streets,and scores the street walkability based on streetscape images,correlates the elements with the walkability scores.The study points out the boundary elements with high impact on walkability and their roles,and provides references for the renewal design of compound lifestyle-type streets.The study shows that the number of elements,the type of perceived boundary elements,and the detailed design of the elements have a high impact on the walkability of the street.In addition,the flexible use of green space elements can significantly improve the walkability of streets.
