A Comparative analysis of proximity to urban services in medium towns in Sri Lanka

Abstract

This research presents a comparative analysis of service proximity in medium-sized towns in Sri Lanka, addressing urbanization's impact on livability and sustainability. By examining service points of interest (POIs) and their distribution within distance-based isochrones, the study evaluates the adequacy of facilities in meeting daily needs. A novel methodology using a facility-to-population ratio and a gravity indicator is proposed to assess service reachability. Findings highlight deficiencies in facility quantity and irregular population dispersion, suggesting an imbalance in facility-to-population support. This approach aids urban planners in developing strategies for sustainable urban environments.
