Neighbourhood Walkability Index for Porto Metropolitan Area

Neighborhood walkability was measured using a geographic information system and resulted from the weighted sum of residential density, street connectivity, and a destination-based entropy index. The index was categorized into quintiles of increasing walkability.<br>More details here:Ribeiro, I. A., &amp; Hoffimann, E. (2018).

本研究采用地理信息系统（Geographic Information System，GIS）测算社区步行可达性（Neighborhood walkability），其对应的社区步行可达性指数（Neighbourhood Walkability Index）由居住密度、街道连通性与基于目的地的熵指数的加权求和得到。该指数被划分为五分位数，以体现步行友好性的逐级提升。
