Abstract
A method is disclosed for representing road intersections as data. A database includes intersection object data entities that represent physical road intersections. Each intersection object data entity includes a maneuver list that identifies each permissible transversal of the intersection from each lane by which the represented intersection can be entered to each lane from which the intersection can be exited from the associated lane by which the intersection can be entered. Each transversal in the maneuver list indicates an entry lane, an exit lane, the geometry of a vehicle path connecting the entry and exit lanes, and an indication of a level of confidence associated with the specified geometry. The database can be used by a system in a vehicle to provide a safety-related function. The database is compatible with navigation-related applications that use a different data model to provide navigation-related functions.
