In this paper, we introduced the working mechanism and calculation process of the GM(1,1) model, then according to the statistical data of the freight volume of the Shanxi province for the period between 2007 and 2013, built the corresponding GM(1,1) model, verified the validity of the model using the statistical data, and at the end, accordingly forecast the freight volume of the province for the next several years.
