ABSTRACT
A shift of transport and land-use planning and evaluation from a mobility to an accessibility basis is logically compelled by transportation theory and would be transformative for both transport and land-use planning, yet the shift is impeded by misunderstandings of the accessibility concept and obstacles to its adoption. This chapter grounds accessibility-based planning in the derived nature of transport demand, and shows ways in which the mobility-to-accessibility shift would affect planning practice. The necessary shift is impeded by issues including a misconstrual of accessibility as urbanism, a focus on positive rather than normative accessibility, the environmental ambiguity of accessibility planning, and others.
