Event-oriented traffic flow prediction method and device

The invention belongs to the technical field of traffic flow prediction, and particularly relates to an event-oriented traffic flow prediction method and device. The method comprises the steps of firstly obtaining reference traffic flow data and target historical traffic flow in traffic flow data related to a trigger event, taking data of historical traffic flow in a preset time as reference data, then obtaining the target historical traffic flow according to a target event type, and obtaining the target historical traffic flow according to the target historical traffic flow. And finally, the increase and decrease value of the historical flow and the target historical flow is obtained, and a prediction result is obtained. According to the method, the prediction coverage range and the prediction accuracy are expanded, low accuracy possibly brought by a single prediction method is avoided, meanwhile, the vehicle flow increase and decrease value is calculated by calculating the total vehicle flow and the standar
