Development of a contextualized spatial network–based walkability (CSNW) index

Today, walkability is a priority in urban planning worldwide due to its positive impact on promoting sustainable cities. Although numerous studies have assessed walkability using various indices, they do not capture pedestrian needs, nor account for spatial variations, nor integrate key methodological considerations from the field of walkability. The novelty of this study is the development of the Contextualized Spatial Network – Based Walkability (CSNW) index to objectively measure walkability at multiple levels (area, route, and location) using a geographic information system – based. It follows a structured methodology, starting with the identification of relevant walkability factors through literature review and expert surveys. To operationalise the CSNW index, the analytic hierarchy process is used to assign weights. Results indicate that accessibility and traffic safety are the most influential factors determining walkability, and pleasurability is the least. Further, the index’s thematic maps reveal significant disparities in walkability levels for different urban segments.
