Research on the Business Application Layer in the Technical Framework of Road Infrastructure Digital System

Abstract

Driven by both the digital economy and new technologies, the construction of digital road infrastructure continues to advance, yet its technical and economic characteristics and development patterns still require deeper exploration. This paper centers on the business application layer of digital road infrastructure systems. It opens with an overview of the scale of China's transportation infrastructure and the backdrop of its digital transformation, highlighting the significance of the research.The business application layer has achieved fruitful results at various stages: in the survey and design phase, diverse methods such as forward design using physical models, BIM-based collaborative design, and virtual model design are implemented in parallel, enhancing the quality and efficiency of design; in construction management, the combination of prefabricated assembly with BIM and RFID, along with digital recording, ensures efficient construction; in operation and maintenance, reverse BIM applications involve multiple key steps, enhancing the precision of maintenance; and in travel services, the MaaS system integrates resources to optimize user travel experiences.However, current construction efforts are plagued by issues such as technological immaturity and a lack of top-level design. There are bottlenecks in technology across various links, and the top-level planning lacks a coordinated framework. Industry standards and processes are chaotic, and the integration of data and models is hindered. Therefore, strengthening technological integration, optimizing top-level coordination, and enhancing service quality are crucial. By doing so, we can promote orderly and efficient construction, contribute to the modernization of transportation, and support the innovative development of the economy and society.
