Accurate traffic flow prediction results can help to reduce traffic congestion, optimize travel routes and improve road capacity, etc. Therefore, a short-term traffic flow prediction model based on GWO-Attention-LSTM is proposed, which can deeply explore the single-factor information features of traffic flow. The model is based on Long Short-Term Memory (LSTM), and Attention mechanism is added to enhance the focus on important information. The initial weight parameter values of Attention mechanism are optimized by Grey Wolf Optimizer (GWO), so as to mine and predict the time series of traffic flow. The traffic flow data of the actual road is simulated and analyzed. The results show that the RMSE values of GWO-Attention-LSTM model decrease by 1% and 2% compared with Attention-LSTM model and LSTM model, respectively. It proves that GWO-Attention-LSTM model has lower prediction error and better model performance by adding Attention mechanism and GWO algorithm.
