However, perceived accessibility, defined as the potential to participate in spatially dispersed opportunities, often poorly reflected by these measures. This paper sets out explain mechanisms that lead mismatches. A conceptual model constructed establish what factors shape accessibility. schematic framework shows mismatches between a indicator and perceptions can stem inaccuracies awareness well measure if fails take account of subjective evaluations accessibility components. When evaluating performance land-use transport system configurations, measures based on data only serve proxies for how actually experienced. argues bringing fore accessibility-based planning, acknowledging with indicators, will advance evolution mobility-based planning. • opportunities conditioned individual perceptions. Calculated proxy actual There no such thing ‘objective accessibility’ opposed ‘subjective accessibility’. Accessibility-based planning should acknowledge focus transition
