基于一次指数平滑法的局限性,提出用分阶段的一次指数平滑法预测公路客运量的方法,实践证明,这种改进的一次指数平滑法具有很好的预测精度。
Based on the limitation of first exponential smoothing method, a method of predicting the amount of highway passenger traffic by using one-stage exponential smoothing method is proposed. It has been proved by practice that the exponential smoothing method of this improved method has good prediction accuracy.
