Abstract

The 15-minute city concept is a measure of the quality of urban life based on proximity, sustainability, and sociality. This study proposes a geospatial framework for calculating the 15-minute city index (FMCI) aimed to measure the accessibility of its residents to six social functions, which include living, working, supplying, caring, learning, and enjoying. Quezon City, Philippines, was chosen for its urban characteristics that aligned with this vision and served as the study area. To account for pedestrian needs, age-based weights were assigned to the social functions, and service areas were mapped using a uniform walking speed. FMCI values were calculated based on weighted social functions and barangay population distribution by age group. Results revealed that 39% of Quezon City’s barangays achieved a perfect FMCI score of one, indicating access to all six functions within a 15-minute walk. Positive spatial autocorrelation indicated the clustering of barangays with similar FMCI values, with hot spots in the southern and cold spots in the northern parts of the city. These findings offer insights for policymakers in improving urban life quality. The adaptable FMCI framework can be applied to other urban areas to assess service accessibility, considering residents' needs.
