The invention discloses a traffic flow data prediction method. The prediction method comprises the steps of obtaining historical traffic flow data related to a to-be-predicted moment; extracting spatial features of the historical traffic flow data by using the trained spatial feature extraction network; inputting the extracted spatial features into a trained time sequence feature extraction network, wherein the time sequence feature extraction network comprises a first long-short-term memory neural network and a second long-short-term memory neural network; wherein the first long-short-term memory neural network outputs long-term time sequence characteristics, and the second long-short-term memory neural network outputs short-term time sequence characteristics and congestion characteristics; and outputting traffic flow data at the moment to be predicted according to the long-term time sequence characteristics, the short-term time sequence characteristics and the congestion characteristics. Compared with a traditional long-term and short-term memory neural network, the long-term and short-term memory neural network based on the ordered neurons is used, influences brought by emergencies can be better captured, and the method is more suitable for variable traffic environments.
