The invention provides an expressway traffic flow prediction method and system, and the method comprises the steps: obtaining the position of a monitoring point in a target expressway region, and extracting the historical traffic flow data of the corresponding monitoring point in a database based on the position of the monitoring point, the monitoring point being a toll station or a portal arranged on an expressway; constructing a first traffic flow prediction vector based on historical traffic flow data of at least one monitoring point existing in a target road section in the target highway area, and inputting the first traffic flow prediction vector into a pre-trained prediction model to obtain a first predicted traffic flow of the target road section at a target time point; extracting external influence factors of the target road section, and calculating corresponding vectors of the external influence factors; and inputting the first predicted traffic flow at the target time point and the corresponding vector for calculating the external influence factors into a pre-trained correction model, and outputting a second predicted traffic flow after the first predicted traffic flow is corrected. According to the scheme, other external influence factors are further considered, and the prediction precision is ensured.
