The invention discloses a traffic flow prediction method and system based on an STNR model, and the method comprises the steps: sorting historical traffic flow data of a target road section according to a time sequence, dividing the historical traffic flow data into long-term data and short-term data, and obtaining a training set; constructing a traffic flow prediction model, taking the long-term data and the short-term data as input of the traffic flow prediction model, and training the traffic flow prediction model; the traffic flow prediction model comprises a full connection layer, a long and short term processing module, a space-time convolution module and a multi-layer sensor module; and collecting traffic flow data of the target road section at the current moment, and inputting the traffic flow data into the trained traffic flow prediction model to predict the traffic flow in the future time period. According to the method, the spatial dependence and the time dependence of the traffic flow are effectively captured, and the prediction accuracy is improved.
