Road operators across Europe are facing the same challenges with digitalisation. In response, the CEDR (Conference of European Directors of Roads) Dublin Declaration in 2024 set out a vision for the digital road manager. The vision addresses several aspects, such as connected and automated vehicles, integrated traffic management, Building Information Modelling (BIM), digital twins, and the Internet of Things (IoT). The ever-increasing amount of data and information available from different sources, and their accuracy, will provide a much more detailed picture of the current traffic situation. At the same time, significantly more data is required for operation and maintenance actions and traffic management purposes. Digital twins, as the next step in the modelling process, allow real-time interpretation of the state of the transport system. When digital twins are combined with geographic information databases and BIM models, the result is Geo-Digital Twins, which can provide maintenance personnel with useful information about the actual load and wear on infrastructure (e.g., bridge monitoring systems). That is why this complex model can be considered the best tool for exploiting the benefits of digitisation.
