From Roads to Emissions: Bibliometric Insights into Transportation and Climate Change Research

The study presents a comprehensive bibliometric analysis of academic literature focusing on the intersection of transportation and its impact on climate change. Covering the period from 2018 to 2023, the research scrutinized a substantial dataset of 4,373 papers from the Scopus database. Employing VOSviewer for network visualizations and Microsoft 365 for data analysis, the study meticulously mapped publication trends and citation impacts within
this period. This systematic approach provided a thorough understanding of the evolution and current state of research in this vital field, highlighting how academic focus on
transportation’s role in climate change has intensified over time. Key findings from the study revealed a significant increase in research output, with the number of publications
nearly doubling from 483 in 2018 to 932 by 2022, indicating a growing scholarly interest in this area. However, the analysis also uncovered notable variations in citation rates, with
a peak citation per publication (CPP) of 24.04 for highly influential papers. This suggests a disparity in the influence of research output, with some studies gaining more recognition
than others. Additionally, the study highlighted significant differences in scholarly production and impact across different countries, with the United States leading in
publications and citations, followed by China and India. These findings underscore the importance of international collaboration in research, pointing to the need for policies that encourage and support collaborative efforts to tackle the global challenge of climate change
through effective transportation strategies.
