A Level of As-Is Detail Concept for Digital Twins of Roads—A Case Study

The recent rapid rise in the demand for digital methods for planning and management of road infrastructure has led to the development of new concepts for structuring the targeted applications where digital methods shall be applied in the future to improve overall efficiency. This transition towards digital planning, maintenance and even coupling digital representations with the asset in the real world requires a clear structure so that existing potential can be optimally exploited. In this paper, we conduct a case study to test and improve our proposed LOADt concept for the digital representation of roads for the use in digital twins. Since digital planning is just emerging in road construction, the road infrastructure sector currently faces the issue of existing roads not having a digital representation. Therefore, this contribution aims at highlighting the path from reality capturing towards the establishment of the digital representation as-is of existing roads.
