Abstract: There are some problems in the existing traffic flow forecasting models, such as low prediction accuracy and high time cost. RFID technology is used to transmit traffic flow data information during urban traffic congestion, and extract information to control the running state of vehicles on the road. The basic parameters of traffic flow are set, vehicle RFID data source is used to preprocess duplicate data and missing data of traffic flow, and differential stationarity and normalisation are processed; LSTM neural network is used to train traffic flow data iteratively and output estimate results. The comparison shows that the MAPE, RMSE and Mae of the proposed model are 12.34%, 23.18% and 15.87% respectively, which improves the prediction accuracy, and the shortest prediction time is about 22 ms.
