比较步行评分、步行偏好和可达性在香港地区新市镇的探索

Comparing Walk Score,Walking,and Accessibility Exploration of a New Town in Hong Kong region

当前步行评估系统及其评价指标越来越复杂多样,且不同评分系统之间难以相互比较,使得设计师和政策制订者难以在实际工作中利用此类评估方法.针对此情况,研究以香港地区沙田新镇为例,调查了使用三维步行网络得出的可达性指数、香港地区最近开发的可步行性评分系统,以及表明步行偏好的实际步行流量水平之间的双变量相关性.在此基础上,文章进一步讨论了网络分析对于现有和预测条件下评估步行可达性的便利性.

Taking Sha Tin new town in Hong Kong region as a case study,this study investigates the bi-variate correlation between simulated accessibility using a 3D pedestrian network analysis,a recently developed 3D walkability scoring system based in Hong Kong region,and actual pedestrian flow levels as walking revealed preferences.Network analysis's relative ease of use for existing and projected conditions evaluation are discussed.
