Investigating the walkability of primary, secondary and K-12 schools across metropolitan Perth, Western Australia

Abstract

AbstractHaving a walkable built environment is important to encourage active school transport. The aim of this study was to measure the walkability of all Perth, Western Australia (WA) schools and investigate whether differences in walkability exist by school type, socioeconomic status (SES) and/or subregion. Geographic Information Systems technology was used to measure walkability (i.e., traffic exposure and pedestrian connectivity) surrounding all Perth schools (n = 651) in 2021. Walkability scores and their individual components were compared using odds ratios and one-way ANOVAs with post-hoc comparisons by school type (primary, secondary and K-12; government and non-government), school SES and subregion. The majority of Perth schools (73.8%) were below the WA Planning Commission’s target for a walkable catchment area. Neighbourhoods surrounding high SES schools were significantly more walkable than neighbourhoods surrounding medium and low SES schools (mean walkability scores: 12.4, 10.5, 10.1, respectively, p < .001). Neighbourhoods surrounding schools located in the Central subregion (mean 12.3) were significantly more walkable than neighbourhoods surrounding schools located in the North-West (mean 11.0, p = .024), South Metropolitan (mean 10.0, p < .001) and North-East (mean 8.4, p < .001) subregions. No significant differences in walkability index scores were found for school type. This study found a large proportion of Perth schools were surrounded by disconnected street networks and that neighbourhoods surrounding high SES schools were, on average, more walkable than neighbourhoods surrounding medium and low SES schools. The results highlight the importance of modifying the built environment to increase opportunities for active school transport, particularly in low and medium socio-economic areas.
