Abstract

Cross-sectional studies have indicated spatial inequalities in public transport accessibility in London, where low-skilled, low-income groups often experience limited accessibility, hindering their access to urban services and opportunities. However, how accessibility to public transport is distributed by demographic groups and how it changed over time have not been studied. This study examined the potential unequal distribution of public transport accessibility with a focus on demographic groups defined by ethnicity, age, and socioeconomic status over the past decade, at the LSOA level in the Greater London Area. After accounting for geographical features, car ownership, population density, and spatial autocorrelation in spatial lag models, the disparities for ethnicity were found, as the mixed and other ethnic groups were more disadvantaged both in 2011 and 2021, while the Asian ethnic groups had a more advantaged position. Income also played a role, as wealthier groups tended to have better access to public transport; however, these privileges decreased throughout the decade. The accessibility advantage of the middle-aged and older groups in 2011 diminished significantly by 2021. This was replaced by the median low-level age group, which had the most prominent advantage in tube accessibility. The research aims to inform policymakers on addressing disparities in public transport, optimising accessibility, and developing a fairer and more inclusive urban environment.
