Patent ID: 8892356

Claim:
A method for representing traffic signals with a road database comprising: storing an intersection object and lane data entities in the road database on a computer-readable medium, wherein the intersection object includes a plurality of maneuver entries that describe permissible traversals of an intersection from a plurality of incoming lanes, wherein a first maneuver entry for the intersection includes a first incoming lane data entity for a first incoming lane into the intersection and an outgoing lane data entity for a first outgoing lane out of the intersection, and a second maneuver entry for the intersection includes a second incoming lane data entity for a second incoming lane and a second outgoing lane data entity out of the intersection, wherein the first maneuver entry and the second maneuver entry include different maneuver geometries for a travel path for vehicles; and storing traffic signal data entities in the road database, wherein each traffic signal data entity identifies each traffic signal at a represented intersection that operates with identical phases and at least one of the plurality of maneuver entries of the intersection object includes a traffic data entity; wherein the road database is used for purposes of representation of traffic signals at intersections located in a geographic area and the representation of the maneuver geometries wherein the first maneuver entry or the second maneuver entry is associated with a confidence value indicative of a probability that a vehicle follows a specified path through the intersection.
