英文摘要：

The matching capability degree of supply and demand of traffic facilities is important to the prospect of the city and the traffic terminal. In the present paper, characteristics of road capacity and traffic demand were firstly discussed. Subsequently, based on neural network approach, a model was built up to predict traffic matching degree. With the model, endowed with the advantage of neural network approach, the data was parallel processed and distributed stored. A nonlinear map was created by training and studying, and finally, prediction was obtained adaptively. The predicted matching capability degree was compared to the experimental data, the result shows that the model possesses the characteristics of high accuracy and good applicability.
