Emerging Trends In Low-Emission Urban Transport: A Bibliometric Analysis Of Sustainable Mobility Technologies

Abstract

This study investigates the intellectual and thematic structure of low-emission urban transport research through a comprehensive bibliometric analysis of 150 peer-reviewed articles indexed in Scopus between 2010 and 2024. Employing co-authorship, keyword co-occurrence, and co-citation network analyses, the study uncovers evolving trends in electric mobility, micromobility, charging infrastructure, and sustainability governance. The findings reveal dominant thematic clusters but also underscore persistent fragmentation, with limited integration across technological, behavioural, and policy domains. Regional analysis highlights a marked underrepresentation of institutions from Africa, Latin America, and South Asia, raising concerns about epistemic equity and contextual relevance. The study is theoretically anchored in Sociotechnical Transitions and Innovation Diffusion theories, offering a lens to interpret knowledge diffusion patterns and paradigm development within the field. It concludes by advocating for inclusive, interdisciplinary, and policy-integrated research strategies to guide sustainable mobility transitions across both Global North and Global South contexts. The bibliometric approach adopted offers a replicable framework for mapping scholarly landscapes and informing future research in emerging policy domains.
