The invention provides a highway reconstruction and extension traffic safety risk factor intelligent identification method and system, and relates to the technical field of traffic engineering, and the method comprises the steps: obtaining a traffic accident data set during a highway reconstruction and extension project, the traffic accident data set comprising various types of risk factor data; performing data enhancement and balance on a small number of types of risk factor data in the traffic accident data set by using an SMOTE algorithm; determining the factor weight of each traffic safety risk factor through an FAHP algorithm; constructing a weighted association rule mining algorithm by introducing the factor weight; and analyzing the risk factor data in the enhanced and balanced traffic accident data set through a weighted association rule mining algorithm, and identifying traffic safety risk factors. According to the method, more critical cause factors of serious accident data and the interaction relation of the cause factors are considered, so that related research results are more effectively applied to reduce the severity of traffic accidents.
