Digital Tunnel Twin Using Procedurally Made 3D Models

A digital twin is a dynamic information model that provides real-time monitoring and controlling functionalities by connecting the physical and virtual environments. This thesis focuses on the road tunnel use case for the digital twins and aims to create a tunnel twin framework for a given tunnel. Extending a previous work that creates procedural 3D models of the Norwegian road tunnels from the NVDB public database, this thesis builds connections to link the static models with the related information. The developed application connects to NVDB and an emulation server that creates sensor data in the absence of the actual and parses them to the usable format in a database for the virtual twin to use. The virtual twin utilizes this information to reflect the real-time changes in the physical environment. The digital twin framework is observed to generate twins for the given tunnel, create solid connections to the given sources, and the virtual twin component can reflect the changes. However, the developed application was working slower than expected, and optimization in database utilization is undoubtedly needed
