Digital and Physical Infrastructure
The adaptation of physical infrastructure and its link with the digital infrastructure is becoming a key factor for the deployment of connected and automated vehicles of higher levels of automation. A common understanding of the PDI role for CAD, specifications of required infrastructure and its interfaces as well as piloting the interaction between vehicles and infrastructure are required to fulfill the requirements of connected and automated driving in 2030.
The “Digital Road infrastructure” may be defined as “the digital representation of road environment required by Automated Driving Systems, C-ITS and Advanced Road/Traffic Management System”.
It can be understood as the integration of multiple geo-located information layers containing:
-Static – Basic Map Database (e.g. Digital cartographic data, Topological data, Road Facilities)
-Semi-static – Planned activities and forecast (e.g. traffic regulations, road works, weather forecast)
-Semi-dynamic – Traffic Information (e.g. accidents, congestion, local weather) – Smart Traffic Management Center
-Dynamic – Information through Vehicle to X communication (e.g. surrounding vehicles, VRU, traffic signals)
