Modeling and prediction of highway traffic flow based on wavelet neural network

The features of highway traffic flow are analyzed. The modeling scheme to predict highway traffic flow is proposed according to these features. The formulas for training wavelet neural network are deduced after the researches on learning process of wavelet neural network. The training algorithm and procedure for wavelet neural network are designed. The prediction model of highway traffic flow based on wavelet neural network is established. The model parameters are adjusted to achieve a good prediction result The prediction result is tested by using actual traffic flow data. The result shows that the wavelet neural network can predict the highway traffic flow accurately.
