The invention discloses an expressway special section risk situation research and judgment method based on a cumulative effect, and the method comprises the steps: S1, analyzing the risk situation index evolution of a characteristic section road section, and constructing a traffic abnormal operation state data set; s2, performing sample expansion on the traffic abnormal operation state data set to obtain an expanded abnormal operation state data set; s3, based on the expanded abnormal operation state data set, constructing a risk cumulative effect evaluation model expanded along the time dimension; and S4, carrying out quantitative analysis on a risk prediction result output by the risk cumulative effect evaluation model to obtain a risk cause. According to the method, the risk situation of the special road section of the highway can be efficiently and accurately researched and judged in real time, and technical support is provided for formulating risk intervention measures.
