Objective. We analyzed the intellectual structure and collaboration patterns in transportation research based on publications from the top 10% highest-impact journals in Scopus. Design/Methodology/Approach. We conducted a bibliometric analysis of scientific output in the transportation field. The sample comprised articles published between 2015 and 2024 in the top 10% of journals with the highest impact in Scopus for this area, resulting in a final sample of 39 journals. The data were analyzed using Gephi software, where network maps were created and centrality metrics were computed. Results/Discussion. The co-word map emphasized the significance of terms related to road safety, infrastructure planning, and sustainability. These clusters demonstrated how current transportation research combines technical viewpoints with interdisciplinary approaches, connecting transportation engineering to public health and risk management. It was observed that the papers with the highest centrality concentrated on methodological studies in transportation modeling, as well as research on system resilience and vulnerability. Regarding international collaboration, the results confirm trends identified by previous studies, with the United States, China, and the United Kingdom playing central roles in the collaborative network. Conclusions. The results of this study confirm that transportation research is increasingly adopting multidisciplinary approaches, with road safety and sustainability becoming core interconnected issues.
