A Multi-Indicator Spatial Accessibility Analysis of Living SOC Facilities in Seoul’s Living Areas - Implications for Spatial Equity and Urban Policy for Older Adults

Key Points

• Assess the accessibility of various public facilities for older adults in Seoul to understand spatial equity.
• Conducted a multi-indicator spatial accessibility analysis across 116 living areas for people aged 65 and older.
• Evaluated accessibility using 2SFCA, equity via Gini coefficient, and coverage.
• Implemented a walking network-based 15-minute threshold for facility accessibility assessment.
• Accessibility levels varied significantly by facility type, revealing uneven distribution across living areas.
• Identified overlapping vulnerable types (LLL) in several living areas, highlighting compounded vulnerabilities.
• Demonstrated the necessity of transitioning from single-indicator evaluations to multi-indicator diagnostics for urban planning.
