The Methodology for Assessing the 15 Minute Age-Friendly Walkability (AFW) of Urban Public Spaces

Recent decades have witnessed noticeable demographic changes around the world. The global population has continued to increase steadily and, according to forecasts, the trend will be maintained in the coming decades. An increase in the 60+ population is yet another important demographic change. These determinants pose new challenges for socio-economic, spatial, and transport policies in most, if not all, cities in the world. These policies should be aligned with the global development paradigm to promote sustainable development and sustainable improvement of the quality of life of the present and future generations. In the coming years, the potential of cities should be recognized, resources should be managed rationally, effective spatial policies should be implemented, and user-friendly spaces should be created to promote the development of effectively managed urban areas. Cities are often compared to living organisms, which is why social mobility is a crucial determinant of urban development and is often used in assessments of cities. To address the above needs, a universal and innovative methodology for assessing the age-friendly walkability (AFW) of urban public spaces was developed and tested in the present study. The methodology was developed based on a review of the current trends in age-friendly cities, a survey of the target population, and a self-designed concept for evaluating the walkability of pedestrian routes in public space. The proposed methodology not only contributes to the existing knowledge but also has practical implications because it was tested in a Polish city to classify the 15 minute walkability of pedestrian routes and to identify Strategic Intervention Areas for the 60+ population (SAI 60+). This innovative approach to walkable urban public spaces is a simple tool for developing senior-friendly planning solutions in cities. The developed paper constitutes a basis for precise spatial planning it is based on reliable data by conducting a full and comprehensive spatial inventory of mobility trajectories of older people walkability. The aim of the undertaken research was to improve the quality of urban residents' lives in the context of Sustainable Development Goal 11 (to make cities and human settlements safe, stable, and sustainable). Above all, the study is congruous with the sustainable urban mobility vision.
