The invention provides a traffic flow prediction method and device for a traffic intersection, and relates to the technical field of big data. The method comprises the following steps: acquiring traffic flow data of a traffic intersection in a preset time period; performing deformation processing on the traffic flow data to obtain predicted deformation feature data; performing feature processing on the predicted deformation feature data to obtain predicted feature data; based on the prediction feature data and a traffic flow prediction integrated model, obtaining a traffic flow preliminary prediction result; and carrying out deformation recovery processing on the traffic flow preliminary prediction result to obtain a traffic flow prediction result of the traffic intersection. The device is used for executing the method. According to the traffic flow prediction method and device of the traffic intersection provided by the embodiment of the invention, the accuracy of traffic flow prediction of the traffic intersection is improved.
