Urban road traffic risk restricts the construction of safe cities. In order to scientifically evaluate urban road traffic safety risks, the regional disaster system theory is taken into consideration, and the coupling role of various parts in the regional disaster system is fully considered, and the regional disaster safety risk assessment ideas are proposed; Analyzing the main factors affecting urban road traffic safety risks, we form a framework of urban road traffic safety risk influencing factors based on regional disaster system ideas from four aspects: hazard, disaster bodies, disaster environment and emergency response capabilities; taking a city as an example, we analyze the influencing factors of road traffic safety risks in that city, construct an index system of urban road traffic safety risk assessment, and verify the feasibility and effectiveness of the risk assessment ideas and the framework of risk influencing factors. The results show that the risk assessment ideas and the framework of risk influencing factors have certain rationality, and provide a theoretical basis for effectively preventing the occurrence of urban road traffic accidents.
