This study aims to perform a comprehensive bibliometric analysis of "public transportation," "service quality," and "government intervention" research. To reach our goal, we used the PRISMA protocol and VOSviewer to find the relevant documents in the Scopus database between 2013 and March 2024. A total of 660 documents were analyzed. The results showed an increasing trend in publications over the years-China was the top country in terms of publication outcome. The analysis identified the most productive institutions, such as the "Ministry of Education of the People's Republic of China" and the "Budapest University of Technology and Economics". The analysis also identified the most productive author, such as Duleba, S. The study also identified the most cited document, "Integrating shared autonomous vehicles in the public transportation system: A supply-side simulation of the firstmile service in Singapore". "Sustainability Switzerland" is the most productive journal in the list. The paper identified the most frequent keywords, such as "public transportation/public transport/public transportation system" is the most frequent keyword with 249 occurrences. This bibliometric analysis provides insights into the current state of research in the relevant field. It also provides insights into the direction of future research in this field.
