The invention provides a road traffic flow prediction method based on an ARIMA model and kalman filtering. Firstly, road traffic history data is extracted, and the ARIMA model of the road traffic history data in a time sequence is established; then the ARIMA model of the road traffic history data and a kalman filtering algorithm are combined, and state equations, measuring equations and update equations in a kalman filtering process are obtained; and finally, the road traffic real-time data is extracted. By adopting the road traffic flow prediction algorithm based on the ARIMA model and kalman filtering, real-time prediction of road traffic data is realized.
