High Currency LDM
We detect changes in safety related roadside assets and updates LDM by reflecting the changes up to minutes.
• Concept: Local Dynamic Map is a collection of location-based data. It is a synthesized information on all objects, including road shapes, road signs, vehicles, and pedestrians, presented onto linked layers. HCLDM is a dynamic map with high currency of which information in the upper LDM layer is updated within minutes.
• We classify and register all roadside assets that affect autonomous driving safety in our area and update them in HCLDM by detecting changes. HCLDM is an essential input to the real-time autonomous driving safety assessment algorithm. For significant risks of detected changes shall be reflected in the dynamic ODD.
•Through this, it is possible to prevent autonomous vehicle accidents caused by sudden changes in roadside assets.
