Research on Driving Reliability Evaluation Method under a Rainfall Environment

In view of the severe traffic safety situation, it is an important and urgent research to analyze the characteristics of traffic accidents, curb the high incidence of traffic accidents and reduce the harm degree of road traffic accidents. This paper takes the driving reliability of the traffic system under a rainfall environment as the research object, explores the concept and calculation method of each unit of the system and its overall reliability from the perspective of the system's composition, structure, function and coupling relationship, proposes the reliability evaluation model of the complex system, and conducts case studies. It lays a foundation for the establishment of a safety early-warning theory system of transportation systems under rainfall conditions based on reliability evaluation.
