The construction of transportation infrastructure is not only the foundation of regional survival and development, but also the important foundation of realizing regional functional orientation and improving regional comprehensive competitiveness. The rational allocation of traffic land resources requires the prediction of the limit scale of transportation infrastructure. Through the combination of qualitative analysis, quantitative evaluation and empirical research, a theoretical calculation model for predicting the land scale of highway traffic infrastructure construction based on RR-ARIMA coupling model is proposed. Taking Shandong Province as an example, the total limit scale of regional highway traffic infrastructure from 2022 to 2025 is predicted, and it is concluded that the limit scale of highway infrastructure at the end of the 14th five-year Plan is 79.99-91.58 ten thousand hectares.
