It is proposed that the fixed capacity investment and cargo discharge regression forecasting model and the optimal average information customer distribution model can be used to predict the cargo o - d distribution. the capacity limitation dynamic increment comprehensive network model can be applied to the prediction of the channel cargo transportation discharge and the turnover discharge in the main courses. the main courses network plan grade can be verified by the total cost method, and according to which the economic rationality of constructing different grade channels can be evaluated
