Assessing Walkability in Kathmandu Metropolitan City Through Urban Density and Land Use Diversity Using GIS-Based Analysis

抄録

Walkability is the extent to which built environment is friendly to pedestrians. It plays a crucial role in urban planning and public health. This study develops a GIS-based Walkability Index for Kathmandu Metropolitan City, aiming to assess and quantify pedestrian-friendly environments across its 32 wards. The index integrates three key criteria; Dwelling Density, Intersection Density and Land Use Diversity, using data from OpenStreetMap, Survey Department records, and the Comprehensive Master Plan of Kathmandu Valley. Methodologically, z-scores standardize each criterion for comparability, enabling the calculation of a comprehensive Walkability Index per ward. The results categorized wards into five walkability classes reveal significant variations in walkability levels, identifying areas with high potential for pedestrian infrastructure improvements. The study underscores GIS's utility in urban planning for enhancing sustainability and public health through walkable city design.
