Abstract

To study the identification method of highway traffic risks under the influence of disasters, this paper uses fault tree model, correlation analysis, and Delphi method to identify and analyze the influencing factors of highway traffic operation risks under the influence of disasters. Based on the fault tree model, with "highway traffic operation risk under disasters" as the top event, a progressive analysis of risk factors in dimensions such as disasters, drivers, vehicles, roads, topography, and traffic operation is conducted, and a method for calibrating evaluation indicators for each factor is proposed. The method combines quantitative screening and qualitative analysis to screen and eliminate factors and evaluation indicators with high relevance, low importance, and poor availability, forming a quantitative evaluation indicator form for risk factors. This provides a basis for highway risk management under sudden disasters, and provides technical support for management personnel to control the development of disaster risk trends and reduce economic and property losses caused by high risks.
