Abstract
The 15mC has gained prominence in urban studies, particularly after the COVID-19 pandemic. Beyond providing walking and cycling infrastructure, it emphasizes ensuring residents’ access to essential services and amenities within a 15-minute walk or bike ride. Central to this vision is not only spatial proximity but also the quality and inclusivity of everyday mobility, especially for vulnerable groups. This study examines how well existing built environments support these principles, focusing on older adults (65+) and parents with young children. Walk-Along Interviews were con-ducted in two municipalities of Ankara, Türkiye, where 18 participants shared real-time experiences while navigating their neighborhoods. Interviewers and observers accompanied them during routine trips, capturing perceptions of mobility challenges. The qualitative data were coded and analyzed in MaxQDA, with attention to categories such as access to services (shops, healthcare, public transport) and walkability (sidewalks, crossings, safety). Findings reveal that vulnerable individuals are highly sensitive to infrastructural and environmental barriers and often lack alternative travel options. Consequently, they report lower satisfaction with their journeys and stronger dependence on supportive urban design. These insights highlight the necessity of inclusive planning to ensure that the 15mC achieves its promise of equitable and sustainable accessibility.
