Establishment and Research of National Highway Mileage Prediction Model
[Purposes]Under the background of building a powerful transportation country,the transporta-tion development has changed from relying on traditional factors to focusing on innovation.Forward-looking planning and scientific forecasting have become the premise and foundation of national transpor-tation construction.[Methods]Based on the data of highway mileage published by the National Bureau of Statistics from 2006 to 2020,the prediction models are established by index method,linear method,logarithmic method,polynomial method and power function method.[Findings]After comparison and testing,the results show that the 6-degree polynomial fitting prediction model is the best,and it is opti-mized by adding new annual data.[Conclusions]The 6-degree polynomial prediction model with added annual new data can providereferencefor national highway construction planning.
