The invention discloses a traffic flow prediction method. The method comprises the following steps: S1, obtaining a data set of traffic flow; S2, for different flow acquisition points in the data set,calculating a correlation coefficient between any two flow acquisition points, and generating a correlation coefficient matrix; S3, obtaining a reference point set related to the flow acquisition points according to the correlation coefficient; S4, obtaining historical average prediction values of the flow collection point and the reference point set respectively based on the background information; S5, obtaining a reference collection point weight of the flow acquisition points; and S6, performing weighted summation on the historical average prediction values of the reference point set and the flow acquisition points and the reference acquisition point weights of the flow acquisition points to obtain traffic flow prediction values of the flow acquisition points. According to the method,the flow information of other nodes related to the flow acquisition point is associated and is combined with the historical average value method of the traffic flow, the prediction precision is relatively high, a large amount of computing resources are not consumed, and the computing speed is improved.
