This paper presents a novel methodological framework utilizing Visual Artificial Intelligence (AI) techniques to investigate the relationship between urban design and walkability experiences among older adults, with the goal of deriving design guidelines to enhance their well-being. The study leverages machine learning methods such as Object Detection and Image Segmentation to quantify urban design elements using street-view images. Data from the Hong Kong Travel Characteristics Survey are employed to calculate older adults’ walking choice as a walkability index. Statistical analyses, including Linear Regression and Geographically Weighted Regression, are utilized to explore correlations between urban elements and walkability, considering both quantitative and spatial dimensions. The findings demonstrate significant correlations between specific urban elements like benches, trees, crosswalks, and streetlights with older adults’ walkability. Combinations of urban elements, such as benches and sidewalks, are identified as contributing significantly to enhanced walkability. Qualitative analyses using street view images further inform the development of design guidelines aimed at creating urban environments conducive to physical activity, social interaction, and overall well-being among older adults. The implications of this research extend to the development of human-centric urban design principles and the potential use of machine learning models to predict walkability based on street view images. By considering the human perspective by employing Visual AI technologies, this study provides valuable insights for urban designers and policymakers to create more inclusive and walkable urban environments, particularly benefiting older adult populations.
