Abstract
In recent years, the concept of green transportation has rapidly entered our lives with the increasing awareness of environmental problems such as climate change, air pollution and depletion of natural resources. Green transportation has become a new scientific research area under the umbrella of sustainability due to its benefits to both the economy and the environment. The aim of this study is to provide a common quantitative and qualitative understanding of the overall evolutionary trend, knowledge structure and literature gaps of the sustainable and green transportation (S&GT) research field. For this purpose, the Bibliometrix library provided by R software was used to analyze S&GT-related scientific research in the Web of Science database. In this study, using the science mapping approach, a total of 2018 publications published from 1997 to 2022 were analyzed and synthesized in detail. In addition, visualized statistics on the number of publications, citations, prominent authors, institutions, countries, sources, keywords and research themes in the field of S&GT were analyzed bibliographically. The analysis results show that China is the largest contributing country; Changan University is the most influential institution; Zhang L. is the most influential writer; Sustainability Journal is the primary publishing platform, in the S&GT field. The results are expected to guide researchers interested in S&GT issues to identify research gaps. In conclusion, the findings systematically describe the current state of play, key issues and academic frontiers in the field of S&GT.
