The embodiment of the invention provides a method and a device for predicting pedestrian flow, and relates to the technical field of pedestrian flow prediction. The method for predicting the pedestrian flow comprises the following steps: predicting the pedestrian flow of a to-be-tested target area by utilizing the original data sequence and a preset ARIMA model to obtain a first prediction result;when the first prediction result shows that predicted visitor flow data cannot be generated or the predicted visitor flow data is displayed abnormally, predicting visitor flow of the to-be-detected target area according to the original data sequence and a preset linear regression model to obtain a second prediction result. Due to the fact that the change trend of the pedestrian flow is often uncertain, an accurate prediction result can be obtained no matter how large the change trend of the pedestrian flow changes or tends to be stable, and the accuracy of pedestrian flow prediction is improved.
