Research on the Evaluation System for the Digital Transformation Level of Traffic Infrastructure in the National Integrated Multi-Dimensional Transportation Network

The traffic infrastructure of the National Integrated Multidimensional Transportation Network is a crucial foundational support for building a strong transportation country and a key element in the digital transformation strategy of transportation. This paper focuses on the National Integrated Multi-dimensional Transportation Network and, covering the five sectors of railways, highways, waterways, civil aviation, and postal express, proposes a digital evaluation system for transportation infrastructure. By using an indicator system for the digitalization rate, the study constructs a digitalization rate indicator system for transportation infrastructure through methods such as the Analytic Hierarchy Process (AHP) and Principal Component Analysis (PCA). Historical data from 2013 to 2022 are used for analysis and evaluation. Based on the evaluation results, effective measures and recommendations for the digital transformation of transportation infrastructure are proposed.
