RoadDNA by TomTom is a database using a 3D point cloud of roadside patterns compressed into a 2D view of the roadway. This creates a system requiring little storage space and limited processing requirements, without losing detail. It can be used to deliver highly accurate location information to the on-board system of a vehicle. By matching RoadDNA data with vehicle sensor data in real-time a vehicle knows its location on the road, even while traveling at high speeds or when changes occur to the roadside. RoadDNA is expected to support driverless vehicles.
