Knowledge Map of Climate Change and Transportation: A Bibliometric Analysis Based on CiteSpace

Abstract

Climate change has become one of the leading problems around the world. The transport sector is one of the major contributors to climate change. At the same time, climate change is also affecting transportation facilities and travel behaviour. This study proposed a bibliometric approach to explore the structure evolution development trends of this knowledge domain with a broader search scope and more objective results compared with a manual review. A total of 4073 peer-reviewed articles were collected from the WoS core collection database to conduct scientometric analysis. The collaboration analysis shows that the US, China, and European countries dominate this field, and international organisations’ and government agencies’ reports on climate change form the basis of this research field. A total of 14 co-citation clusters were identified, and the research on climate change and transportation primarily focused on the topics of policy options, travel behaviour, the COVID-19 lockdown, environmental cost, and air quality. Keyword co-occurrence evolution analysis was also conducted to track the latest research trends. Based on the results, we propose trends in four areas for future research. This study provides a holistic knowledge map for climate change and transportation research’s past, present, and future.

Trend analysis of traffic management based on literature data mining and graph analysis tools

“…Shao et al used LLR clustering method to systematically summarize the development process of heavy vehicles [17]. Wang et al conducted keyword co-occurrence evolution analysis to track the latest research trends based on improved LLR clustering method [18]. With the development of intelligent technology, machine learning based methods were also introduced for traffic management.…”

Assessing the Role of Hydrogen in Sustainable Energy Futures: A Comprehensive Bibliometric Analysis of Research and International Collaborations in Energy and Environmental Engineering

“…The development of hydrogen technologies and their applications in energy and environmental engineering are the subject of intensive scientific research, which is reflected in the growing number of publications. In this context, bibliometric analysis is a valuable tool for understanding research trends, mapping the field of knowledge, and identifying key countries, collaborations, and potential development directions [44][45][46][47]. Using the CiteSpace program 6.2.R6 Advanced to conduct such an analysis allows the visualization The development of hydrogen technologies and their applications in energy and environmental engineering are the subject of intensive scientific research, which is reflected in the growing number of publications.…”
