Building a Digital Twin
Murphy Surveys used LiDAR technology to capture detailed scans of the buildings and infrastructure. TRL’s own survey team enriched the model with details of the pavement and surrounding areas for a more detailed 3D model. 3D Repo was able to create basic building models where required to build out the site model. Finally, a 3D model was made in Autodesk Revit, utilising the captured data. The final model was then federated in 3D Repo.
Using the Here Maps integration in 3D Repo, the BIM models can be placed on top of a base map layer according to its London location, with live traffic data also being visually fed through to further enrich the model.
With a detailed model in place, simulation company, Immense can create highly detailed simulations and provide analyses and insights to all stakeholders involved in mobility systems planning. These simulations consider real-world environmental factors.
Benefits of BIM for CAV
Better Planning & Understanding
Detailed data is collected to create a digital twin, including precise geometry layout of the road and roadside to aid in project planning and understanding.
New information is discovered during the creation of the BIM models, allowing for real-world scenario planning and testing e.g. testing the effect of faded road markings on CAVs.
Collaboration & Communication
With a BIM model everyone involved can easily visualise the project and have access to the most up to date information whenever they need it.
A Digital Asset
A digital twin provides information on the whereabouts of existing assets and aids in deciding the best locations when installing new hardware.
The BIM model can be used as an SMLL Asset Management Tool, with location and properties of all SMLL roadside assets that have now been captured.
