Combination forecasting model based on total demand forecasting of highway construction in Guangdong Province

摘要：

To forecasting a reasonable size of the future road network in Guangdong Province, this paper respectively use multivariate linear regression prediction method and the gray prediction method to predict. Then make combination forecasting in accordance with the smallest error sum of squares principles. Ultimately determine the future total demand for highway construction of Guangdong Province. Through the error analysis, the results show that the combination of forecasting methods can effectively reduce errors and improve accuracy.
