Sustainable Accessibility for All reframes transport policy around access rather than movement, displacing the inherited assumption that mobility provision can be measured by kilometres, vehicles or infrastructure coverage alone. Its iconic idea is that equitable transport must be judged through the ability of differentiated persons and territories to reach opportunities under sustainable conditions. The report’s contribution lies in assembling a policy architecture where socio-demographic factors, settlement patterns, modal suitability, land-use planning, digital connectivity and governance are treated as mutually constitutive. Methodologically, it operates through a framework of person-based metrics, territorial differentiation and institutional coordination, replacing abstract network performance with situated accessibility diagnostics. Its bridge to the wider field is decisive: it links transport planning to social inclusion, spatial justice, behavioural change, land-use integration and participatory governance, making accessibility not a subcategory of mobility, but the normative and analytical centre of contemporary transport policy.
