ES-PT, Extended Sensors, Complex manoeuvres: HD maps

Use Case Category: Extended Sensors
User Story: Complex manoeuvres in cross-border settings: HD Maps
Location: Spain-Portugal (ES-PT) cross-border corridor

According to 3GPP TS 22.186 R16, Extended Sensors “enable the exchange of raw or processed data gathered through local sensors or live video data among vehicles, RSUs, devices of pedestrians and V2X application servers. The vehicles can enhance the perception of their environment beyond what their own sensors can detect and have a more holistic view of the local situation”.

Scenario 3: HD maps:

This use case focusses in the capability of automated vehicles and road-side infrastructure to detect changes in the road and the HD-Map used for driving, and in sending these changes to the ITS-Centre in order to centralise and broadcast this information to the other approaching vehicles.

Lasers, cameras and traffic radars information can be fused with D-GPS and HD-Maps data, in order to determine changes in the stored information. This information can be measured in terms of length of the event, changes in road description (number of lanes, width of the lanes), dangerousness of the situation, etc.

Finally, obtained data is shared with the ITS-Centre in order to be stored and shared with other vehicles, ensuring the information reaches all the relevant vehicles.
