Analyzing the current research landscape in the field of intelligent connected transportation technology, determining its development direction, predicting future trends, and clarifying the current stage and future research focuses play a crucial role in advancing this field in China. In this paper, we employ bibliometric methods to analyze the knowledge map by examining the frequency of key words, publishing institutions, and journals. We interpret the research hotspots, considering the current development of intelligent connected transportation technology and relevant literature from the core databases of Web of Science. By comparing research hotspots domestically and internationally, we found that: (1) domestic research started later but has produced more results; (2) domestic research in the field of intelligent connected transportation technology focuses on the development of communication systems, control systems, etc., whereas foreign research primarily focuses on the development of driver assistance systems, predictive control models, traffic safety in networked environments, etc. Summarizing the above information, this paper concludes that the field of intelligent connected transportation technology is currently in a rapid development stage, with various new technologies emerging continuously. In terms of publication volume, China and the United States hold the top two positions and are the main contributors to research in this field.
