The invention provides a traffic flow prediction method based on fusion delay reconstruction and GRU-SVR, and the method is characterized in that the method comprises the following steps: S1, carrying out the data cleaning and normalization processing of historical traffic flow data, and obtaining a historical traffic flow data sequence; s2, selecting i continuous historical traffic flow data in the historical traffic flow data sequence as a first feature group; s3, reconstructing the historical traffic flow data sequence according to a coordinate reconstruction method to obtain a phase space; s4, according to the first feature group, obtaining continuous 2 * k + 1 historical traffic flow data from the phase space as a second feature group; and S5, inputting the first feature group and the second feature group into the GRU-SVR model to obtain a traffic flow prediction result corresponding to the historical traffic flow data. In a word, the method can obtain a more accurate traffic flow prediction result.
