Supplementary materials for: Urban Density and Accessibility: A methodological approach

The built environment's impact on human behaviour is well-documented. Still, quantitative research on the topic usually focuses on a large scale, with few studies at the neighbourhood level. This study presents a method investigating the correlation between the local built environment densities and accessibility. We propose a three-step approach using kindergartens in the Stavanger region, Norway, as a case. First, through GIS, we estimate the kindergartens' serviceability as a function of accessibility using 10-minute walking isochrones. Second, we statistically compare the results with density quantifications to explore the relationship between the built environment and kindergarten access. Third, through field observations, we record the travel modes used to access five kindergartens in areas representing the region's built environment diversity. The results demonstrate that populations in denser areas are more likely to walk with their children. However, the research reveals that over 12% of the region's residents live beyond a 10-minute walking distance to kindergartens, making them reliant on cars to access this service. This study aims to provide an adaptable and replicable method to evaluate accessibility to a range of crucial facilities in cities. The findings from such analyses can help optimise the built environment and the provision of services in more sustainable ways.
