The relevant research on the freight transportation demand forecast is always hot topic in academia. In this paper, we discuss the deficiencies between multiple linear regression model and nonlinear regression model based on regression analysis. We can know that simple linear regression model based on regression analysis is better fitted than others. Therefore we use SLR method to make the fitted value approach to the real freight volume. Analysis of the mechanisms leading to the increase of regional logistics transport value demonstrates the need for a more effective prediction which will be the subject of future research.
