A Review and Perspectives on Complex Network Theory and Its Application in Transportation System Resilience

Transportation system resilience, as a core element of transportation safety research, has been receiving extensive attention. In recent years, complex network theory has provided new perspectives and directions for the study of transportation system resilience, but few scholars have systematically sorted out the existing research on complex network theory in transportation system resilience. Therefore, this paper firstly analyzes the development trend, publication distribution and hot keywords of transportation system resilience by using bibliometric analysis and summarizes the research hotspots in this field. Secondly, from the definition of transportation system resilience, the existing research is sorted out from three aspects: evaluation indexes and evaluation methods of transportation system resilience, simulation modeling of disruption scenarios, and optimization strategies of transportation system resilience. Finally, the main problems and challenges faced by the existing research are summarized systematically, and the future development direction of transportation system resilience is proposed.
