Zusammenfassung:A lane identity in a roadway in which a vehicle is traveling can be determined. The roadway can include a plurality of lanes. The determining can include generating a lane identification confidence belief indicating a probability that the vehicle is in a particular lane of the plurality of lanes of the roadway. Generating the lane identification confidence belief can be based on: any detected lane crossings, the number of lanes in the roadway, the lane marker type to a left side and to a right side of the vehicle at the current position of the vehicle or ahead of the current position of the vehicle in a forward direction of travel of the vehicle, and a weighted average of an instantaneous lane identification confidence belief and a lane identification confidence belief prior to a current sample time period.
