ABSTRACT: This paper situates itself within the current transport planning debate by enquiring into the underlining values and beliefs internalised by professional transport planners, and how such values and beliefs play out against institutional and practical constraints planners face daily during their attempts to develop transport systems in a more sustainable manner. This paper presents a starting point of research derived from a literature review as part of an on-going PhD Higher Degree by Research project that the author is currently undertaking. Findings from the literature review revealed two findings: 1) an over-emphasising of the built form’s ability to alter travel behaviour which under-emphasises the role of transport planner, which feeds into 2) an under-appreciating the crucial role that integrating various transport modes together might play towards achieving more sustainable transport outcomes. These findings have lead to the belief that attention should be placed towards developing a normative mobility framework. Building on current new theories of mobility (Urry, 2007) and more recent work related to “pathdependent and institutional inertia” (Low & Astle, 2009), a normative mobility framework as discussed seeks to understand the values, beliefs and practices of professional transport planners and how institutional arrangements are perceived by the actors. Conceptual development of such a framework borrows from practice and normative theories which are therefore briefly explained.
