Covid-19 in Transportation: A Comprehensive Bibliometric Analysis and Systematic Review with a Reappraisal

This paper explores the impact of COVID-19 on public transportation systems through a bibliometric analysis, systematic review, and reappraisal. A systematic review analyzes literature, identifies trends, and provides comprehensive insights. Metadata from Harzing's Publish or Perish via Scopus is utilized, with analysis conducted using tools like MAXQDA's Wordcloud, VOS Viewer for visualization, BibExcel, Citespace, and Mendeley for referencing. The study aims to comprehensively assess the existing literature, including publishing trends, research areas, and identifying knowledge gaps. It evaluates the quality of research and offers suggestions for future studies. The analysis reveals a significant increase in COVID-19 and transportation research since the pandemic's start, particularly in 2020 and 2021. Key themes identified include the pandemic's impact on public transportation, the effectiveness of health and safety measures, and the role of technology in mitigating the spread of the virus. The assessment also highlights research gaps, such as the need for studies on the long-term effects of the pandemic on transportation systems and its implications for social equity. This bibliometric study, systematic review, and reassessment provide valuable insights for current transportation research. The findings can guide future projects and assist policy-makers in developing effective strategies to minimize the pandemic's impact on transportation infrastructures.
