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）对社区步行可达性（Neighborhood walkability）进行测算，其计算方式为居住密度、街道连通性与基于目的地的熵指数（entropy index）的加权求和。该指数按步行可达性由低到高划分为五个五分位数组。
