摘要
Abstract
In order to forecast the highway freight volume effectively, a forecasting model of highway freight volume was constructed by using the BP neural networks based on the history data of highway freight volume of Nanning. The model was coded and operated under the environment of MATLAB soft⁃ware, and the predictive value was got by training and studying the data. This forecasting model of freight volume which was based on BP neural network was proven to be effective though the example analysis. In order to prove the differences between different forecasting methods, the trend extrapolation method, three exponential smoothing method, and gray prediction method were used to forecast the freight volume of Nanning. And through comparative analysis, the relative error of different methods can be got. It is observed that the freight volume forecasting model based on BP neural network has a bigger superiority than traditional forecasting method. The BP neural network model can reveal the nonlinear re⁃lation of freight volume, and fit the raw data accurately.关键词
