| Abstract: | Aiming at the randomness and complexity of urban traffic system,the GM-BP neural network forecasting model of the traffic volume was built based on the grey theory and BP neural network.Then,the combination forecasting model was used to forecast the traffic volume of urban road.The results showed that the average relative error of the forecasting results in GM-BP neural network model was 1.17%.Compared with the grey model,the GM-BP neural network forecast model has better prediction precision. |
