Public Transport Inequality and Utilization: Exploring the Perspective of the Inequality Impact on Travel Choices

Abstract

Public transport (PT) inequality is evidenced to have adverse consequences on various social–urban–economic aspects of urban residents’ lives; however, the impact of this inequality on PT itself, particularly its utilization, is a less explored area of study. This paper examines the association between PT inequality and PT utilization patterns in Melbourne, Australia, using journey-to-work data in a multivariate regression model. By analyzing commuting and socioeconomic factors, we investigate how PT inequalities affect the travel choices of the residents. Our findings indicate that regions with lower PT inequality demonstrate higher PT usage for daily commuting, emphasizing the importance of the equitable distribution of resources. This finding is consistent across different PT modes of trains, trams, and buses, and using different inequality measures of the Gini index and the 90/10 ratio. Spatial variations and factors like income levels, education, home ownership, and age are also found to influence PT usage. The findings offer valuable insights into the potential impact of incorporating equity considerations during the planning stages of PT projects. Furthermore, they could justify targeted interventions aimed at enhancing the equity of PT services.
