摘要: Abstract Service effectiveness (SEV) of bus transit indicates the impacts and quality services. In any given city, not all residents enjoy same level accessibility to supply, with socially disadvantaged groups (SDGs) having more limited access. This study aims measure SEV in terms investigate social equity among various population from a sustainability perspective. A systematic methodology is proposed integrating cumulative opportunity data envelopment analysis (DEA) order assess accessibility-based service (ABSEV) transit, employing Lorenz curves Gini coefficients explore ABSEV. Using elderly as an example SDGs, empirical application Edmonton, Canada provided. The results indicate that 18% total census tracts (CTs) perform effectively ABSEV assessment while remaining ineffective CTs are divided into three spatial clusters. For both seniors population, under 0.5. findings can provide policy makers evidence on how balance distribution improve benefits enhance sustainable development urban systems.
