Okyere and colleagues demonstrate how a mundane activity—walking—can expose the epistemic bias of urban planning. In Accra Newtown and Dome, participatory mapping, seventy qualitative interviews, policy analysis, photo elicitation and a forty-person stakeholder workshop reveal a mobility system in which walking is widespread but institutionally under-recognised. The iconic contribution is the conversion of lived walking experience into shared planning evidence. Maptionnaire allows residents to document both objective conditions and subjective feelings, particularly valuable where formal local data are scarce. The theoretical operation therefore links mobility justice to knowledge co-production: infrastructure deficits become legible through the experiences of those who traverse them daily. The bridge to healthy-city research is immediate, because walkability is connected to safety, social relations, physical activity and wellbeing. Yet the deeper contribution is epistemological: planning becomes more equitable when everyday expertise is admitted into the production of the urban problem itself.
