Abstract
To clarify the research status and development frontier in the field of transportation science and technology,based on the bibliometric analysis method,59 440 articles in the field of transportation science and technology included in the core database of WOS from 2020 to 2024 were systematically combed,and the knowledge graph analysis of the number of publications,publication areas,research themes and research trends was carried out through VOSviewer software.The results show that:from 2020 to 2024,China has become the largest contributor to the number of published papers,accounting for 43.15%,followed by the United States and Germany,ranking second and third,respectively;Among the top 20 research institutions in the world by publishing papers,Chinese institutions account for 13 seats;There is close cooperation between countries and institutions,mainly between China and the United States.The research themes are clustered into five major areas:low-carbon vehicle equip-ment,autonomous driving and vehicle cooperative perception research,traffic information technology,comprehensive traffic safety management and risk identification,and traffic information security re-search.Through the analysis of highly cited papers,it is further clarified that the research hotspots are:transportation system design,network performance optimization and operation management,integrat-ed traffic communication safety and signaling,autonomous driving trajectory prediction and safety,au-tonomous driving and vehicle collaboration technology research.In the future,the research will contin-ue to explore the frontiers of artificial intelligence technology,sustainable transportation system and transportation network resilience,and present the characteristics of"technology-system-society"three-dimensional collaborative evolution,driven by artificial intelligence,information technology,green en-ergy and other technologies,emphasizing the coordination and resilience improvement of transporta-tion modes,and focusing on people-oriented and social ethical constraints.关键词
