The invention relates to a traffic flow prediction method, device and equipment. The method comprises the following steps: acquiring traffic flow information of an intersection; slicing the traffic flow information based on a preset sampling period to obtain a plurality of pieces of historical traffic flow information, wherein the historical traffic flow information comprises the total phase flow, the corresponding date and time, the sampling period and the flow of each lane of the intersection; constructing a prediction vector data set according to the historical traffic flow information; establishing a Seq2Seq model based on an LSTM network and a coding and decoding structure; obtaining single lane flow prediction information according to the Seq2Seq model and the prediction vector data set; and obtaining the similarity between the flow of each lane of the intersection and the total phase flow according to the flow of each lane of the intersection and the total phase flow so as to obtain total phase flow prediction information. Single-lane flow prediction information is obtained according to historical traffic flow information, and short-time traffic flow information of a single intersection is predicted in combination with correlation of the flow of each lane.
