This research explores how social equity is understood, measured and prioritised in UK transport strategies The Oxford Transport Strategy and the London Mayor's Transport Strategy were examined through strategy analysis and expert interviews to understand how and why social equity policies/objectives were conceptualised and prioritised within each strategy. Surveys with the public were then undertaken to explore whether the strategies are consistent with the public's needs and definitions of social equity. This research aims to add the limited body of work around social equity definitions in the transport sector and transport strategy analysis and provides recommendations as to how social equity might be more effectively incorporated and measured in transport strategies in the future.
