摘要:推进交通基础设施数字化既是国家战略，也是促进交通行业现代化转型发展的需要。交通基础设施的数字化信息模型可以作为多源数据和各种信息的载体，因而创建数字化信息模型是交通基础设施数字化的关键技术。目前，有关交通基础设施数字化的标准规范和技术比较缺乏。本文基于交通行业工作实践，从技术研究和工程应用角度对交通基础设施数字化的关键技术进行研究，探讨了BIM技术、倾斜摄影和三维激光扫描进行数字化的技术路线，并对数字化技术发展进行了展望，提供了将交通基础设施由物理实体转变为数字资产的经验。

Abstract: Promoting the digitization of transport infrastructure is not only a national strategy, but also the need to promote the modernization and transformation of the transportation industry. The digitalized information model of transport infrastructure can be used as the carrier of multi-source data and various information. Therefore, the creation of digitalized information model is the key technology of transport infrastructure digitization. At present, there is a lack of standards, specifications and technical about the digitization of transport infrastructure. Based on the author′s work practice in the transportation industry, this paper studies the key technologies of transport infrastructure digitization from the perspective of technical research and engineering application, and discusses the technical routes of BIM, oblique photography and 3D laser scanning, the development of digitalized technology is prospected, and the experience of transforming transport infrastructure from physical entity to digital asset is provided.
