Claim One:
1. A method for representing intersections with a road database comprising: storing in the road database intersection object data entities that represent physical road intersections, wherein each intersection object data entity includes a maneuver list that contains entries that identify all permissible traversals of the intersection to all lanes from which the intersection can be legally exited from each one of all the lanes by which the intersection can be entered, wherein each entry in the maneuver list indicates a lane into the intersection; a lane out of the intersection; and a geometry indicating a vehicle path connecting the lane into the intersection and the lane out of the intersection, and wherein at least some of the physical road intersections represented in the road database have a configuration in which multiple lanes exiting an intersection are legally accessible from a single lane entering the intersection and for such intersections the maneuver list identifies the permissible traversals to said multiple lanes from said single lane.
