Routes to justice: bridging conceived and perceived public transport accessibility through user participation
摘要
Inequalities seem to have grown in recent urban mobility concerns, both from social-spatial (stemming from the center-periphery pattern) and social health (deriving from a wide range of vulnerability situations) perspectives, leading to a comprehensive literature considering transport justice. Accessibility, as conceived by scholars and practitioners, is employed to reveal the inequalities in accessing various components of participation in urban life. The related assessments, sometimes referring to Sen’s capability approach, are city-scale, mainly quantitative studies. By contrast, particular attention has been recently given in the literature to perceived accessibility, especially in experience-oriented approaches—including disability studies—that focus on the most vulnerable populations. These approaches are virtually never integrated into overall accessibility analyses. However, public authorities need to confront the discrepancy between conceived and perceived accessibility in order to implement relevant strategies for different populations and places: while studies relying solely on quantitative methods fail to capture the complexity of accessibility gaps—particularly their intangible dimensions—they remain essential for spatializing and prioritizing accessibility interventions. After having discussed people-oriented accessibility, which theoretically makes it possible to combine quantitative and qualitative approaches, the present paper offers a participative process to include vulnerable populations in 3 different socio-cultural and administrative contexts. The results comprise a set of modelling-compliant accessibility barriers defining the main gaps to be addressed in each city. The findings are analyzed from thematic, methodological, conceptual, and operational viewpoints.
