1. A method for vehicle navigation, the method comprising:

  • receiving, using a processor, probe data from vehicle camera sensors from a plurality of vehicles at a road segment, the probe data comprising lane marking data for the road segment;

    identifying, from the probe data for each vehicle of the plurality of vehicles, any lane markings present for;

    (1) a left boundary of a lane of travel, (2) a right boundary of the lane of travel, (3) a left boundary of an adjacent lane to the left of the lane of travel, and (4) a right boundary of an adjacent lane to the right of the lane of travel;

    coding the identified lane markings present for (1) the left boundary of the lane of travel, (2) the right boundary of the lane of travel, (3) the left boundary of the adjacent lane to the left of the lane of travel, and (4) the right boundary of the adjacent lane to the right of the lane of travel, wherein solid lane lines, dashed lane lines, and unidentified or non-existing lane lines are each assigned a numerical identifier;

    compiling the coded lane markings from the plurality of vehicles at the road segment in a database as a combination code, the combination code being a series of the assigned numerical identifiers in order of the left boundary of the adjacent lane to the left of the lane of travel, the left boundary of the lane of travel, the right boundary of the lane of travel, and the right boundary of the adjacent lane to the right of the lane of travel;

    determining a number of lanes at the road segment from the coded lane markings;

    generating a navigation command for a vehicle based on the determined number of lanes at the road segment; and

    routing the vehicle through the road segment using the generated navigation command.
