摘要
针对研究不同站域步行化改造步行便利之增量变化,对上海11个轨交站域建立不同历史阶段的步行化改造模型。同时,结合地块城市基面的总公共空间面积供应量,进行物质环境指标的整合,从而建立:1)总公共空间供应量;2)可达性在步行改造中的变化数值(sDNA指标);3)活动量内外均衡性指示剂三者的相关性拟合方程。通过验证33个商业地块行为学活动量,证明综合了前两者指标的公共空间疏解指数(MIPS)可以对轨交站域空间活力的延续性产生积极影响,对比综合前得到了提升。此外,得出公共空间立体协同度等其他具参考意义的指标,以作为设计参考,对现有轨交站域地块开发提供建议。
Based on the analysis of 11 rail transit stations in Shanghai,this research establishes a pedestrian transformation model of different historical stages,showing diachronic changes in the increment of walking convenience in the process.After the synthetic process of the supply of public space areas and the increment as physical environment features to innovate a new index,it examines the correlations among the pedestrian system renovation accessibility increments brought by the pedestrian transformation of rail transit station areas,the public space supply and the activity evenness between the interior and exterior of the urban base areas as key indicators.It thus helps to build up a line regression model between MIPS and indicators.After verifying the behavioral indicators of 33 commercial plots and blocks,it testifies that the MIPS,synthesizing the accessibility changes and public space supply,proves to have a relatively more positive impact than the variables before the combination of the evenness of space activities in the rail transit station areas.The 3 D synergy index of public space and other indicators tested in the process can be applied as references in designs,providing inspirations for the development of the existing rail transit station areas.
