In recent years, the concept of intelligent highways has increasingly become the focal point of research within the realm of smart transportation. A significant number of scholars, particularly in recent years, have conducted extensive research on intelligent highways. Utilizing CiteSpace software and incorporating the work of researchers, this paper compiles relevant articles from the past decade concerning intelligent highways and analyzes the current research content, directions, and trends in this field. The results indicate that core technologies such as vehicular networks, vehicle-road coordination, and digital twins dominate the majority of current research on intelligent highways. The studies primarily revolve around the composition and specific application methods of these core technologies. The overall progression of intelligent highways research has seen notable surges in activity, particularly in the years 2015 and 2018, with key terms relating to the aforementioned core technologies driving these waves. In recent years, research on intelligent highways has also begun to focus on specific application scenarios. Looking forward, it is anticipated that there will be an increase in technology-related research, with a particular emphasis on more detailed methods of application and operational contexts.
