In Korea, there have been conversations about promoting the planning of walkable communities based on Chrono-Urbanism, a concept that is the foundation of the 15-minute city, in which residents can get services necessary for their daily life in the same place where they live. Chrono-Urbanism-based planning support assesses the walkability of services for various age groups based on the distance to reach physical activity centers such as walking and bicycling from small living area units, and places essential living infrastructure or urban amenities. Using Free and Open Source Software for Geospatial (FOSS4G), we create a tool that supports the evaluation of walkability and the distribution of urban amenities while taking age groups, walking, bicycle, and public transportation accessibility into account. In conclusion, this tool can measure and distribute urban amenities based on walkability providing a way to create healthier, more equitable living areas. Implementing the tool to produce a range of alternatives will help planners to learn about desirable walkable urban amenity options from the alternatives.
