| Abstract: | The research of short-term traffic flow is reviewed first.Based on analyzing the highly non-linear characteristic and researching the advantage of wavelet neural networks in handling non-linear and unsteady signal,the adaptive of wavelet neural networks on forecasting short-term traffic flow is researched and a forecasting model utilizing wavelet neural networks is put forward.Besides,through the practical flow data of a cross in the city of Suzhou,a nonlinear regressing model is built using wavelet neural networks.The result confirms the reliance and it can help the forecasting of urban dynamic flow,and it can also provide fundamental data for the intelligent traffic systems. |
