Bibliometric analysis of equity in transportation

Abstract

This paper aims to map the research landscape in equity and justice in transport and mobility, identifying key publications, authors, institutions, and interdisciplinary connections to inform future research and policy development. A systematic search of scientific articles on equity and justice in transport and mobility was conducted in the Web of Science, resulting in 759 selected articles that were analyzed using bibliometric and network analysis methods. The analysis reveals a growing trend in scientific production since 2013, with the Journal of Transport Geography, Transport Research Part A: Policy and Practice, and the Journal of Transport Policy being the most prominent journals. The most influential authors and institutions are identified, along with the most cited works. Keyword usage trends and thematic analysis show a shift in focus from environmental equity to urban transport, congestion, and accessibility. Cluster analyses highlight focal points and themes, such as accessibility, mobility, social aspects, transport and spatial equity, environmental justice, transport planning, active transport, and methodological evaluations. Co-citation networks reveal three major clusters with differing research focuses: Lukas K. & Martens K.; Litman T. and Currie, G., and Scwanen T. and Cresswell, T. The findings contribute to a better understanding of the existing knowledge in equity and justice in transport and mobility, enabling researchers and policymakers to identify areas requiring further exploration. Additionally, the paper fosters interdisciplinary connections and sets priorities for future research and policy development.
