“…Considering that the traffic flow has a weekly periodicity, the traffic flow at the current moment is similar to that at the same time last week, and the difference is used to subtract the traffic flow at the same time last week from the traffic flow at the current moment. (2) LSTM1 and LSTM2 represent single-layer LSTM and double-layer LSTM, respectively, and the number of hidden layer units is 64; (3) GRU1 and GRU2 indicate that single-layer GRU and double-layer GRU are used, respectively, and the number of hidden layer units is 64; (4) e expansion coefficient of each layer of DCFCN is [1,2,4,8,16,32], the number of convolutional kernels of each layer is 32, and the size of convolutional kernels is 4. As can be seen from Table 2, compared with other comparison models, the proposed DCFCN has the best prediction effect and the lowest in RMSE, MAE, and MAPE indicators.…”
