By analyzing the original GM(1,1) model and according to the one factor affecting prediction accuracy,a novel improved GM(1,1) model is given in this paper.Moreover,the novel model has been used to forecast result of the road transportation demand from 2010to 2015.Finally,according to the experimental results,the proposed methods obviously could improve the prediction accuracy better than the original GM(1,1) model.So,the method is an efficient and effective approach.
