Inclusivity is a core commitment of the New Urban Agenda of UN Habitat (adopted in 2016). Moreover, the Rail Sustainable Development Principles call for railway developments that are customer-driven, putting rail in reach of people, providing an end-toend journey, being an employer of choice, reducing our environmental impact, carbon smart, supporting the economy, optimising the railway and being transparent (RSSB, 2016). However, research suggests there is still a long way to go before ''we live and work in an inclusive world" (Clarkson and Coleman, 2015). To consider these matters, this review searched for on-line library sources employing keywords including transport, inclusivity, circulation, severance, level of service, pedestrian movement within journal articles, conference papers, theses, books and government papers. The review commences with a review of older views and goes on to critically assess potential innovations in contemporary scholarly literature. Earlier research discusses general factors that influence station design include context, location, platform, train length, and depth of construction, geological, engineering, property constraints and passenger demand (Harding, 2011). This critical review considers the scholarly literature concerning inclusive design issues in transport buildings. It explores, (i) gaps in canonical pedestrian movement theory affecting inclusivity, particularly vertical severance (VS), (ii) the size, shape and selection of circulation elements affecting Level of Service (LOS), and (iii) key measures of crowdedness and inclusivity. Potential innovations include, (i) new 'designerly ways of knowing' about lack of inclusivity, and, (ii) the use of Agent Based Modelling (ABM) for gaining insights into the movements of diverse agents over time (as well as the evaluation of rival cases). Anticipated benefits include a strengthened 'transport chain', less VS, enhanced empathy, and improved user experience and safety. More research is needed in this field, particularly owing to the significant cost and time in developing urban railway projects. This review identifies key research questions that require further investigation. It argues that integrating LOS theory and design praxis will result in safer and more inclusive stations that contribute more to society. It is hoped that this review contributes to this slowly growing body of knowledge of inclusivity within the field of transport.
