'Accessibility' has become commonplace in transport planning and as such there is a plethora of interpretations of what accessibility means, what constitutes a good measure of accessibility, and how this might be applied in practice. This paper presents an overview of approaches to measuring accessibility and presents a case study of Accessibility Planning in England — one approach to formalising the concept of accessibility. Results of semi-structured interviews with local authority officers are discussed to establish whether current approaches, allow their desired outcomes to be met. This approach demonstrates where there might be gaps between measured or modelled accessibility and the perceptions of the individuals. Findings suggest that while the process is deemed useful in raising the profile of accessibility issues, measures of accessibility do not necessarily easily translate into quantifying benefits of those improvements that are perceived by practitioners to improve accessibility and reduce transport disadvantage
