1. A method comprising:

  • receiving a plurality of instances of probe data, each instance being from a probe apparatus of a plurality of probe apparatuses, the probe apparatus comprising a plurality of sensors and being onboard a vehicle, wherein an instance of the plurality of instances of probe data comprises location information indicating a location of the corresponding probe apparatus;

    for each of one or more instances of the plurality of instances of probe data, determining a distance parameter based on the location information and a road segment corresponding to the location;

    based on a vehicle lane pattern for the road segment, identifying a most likely lane for each instance of the plurality of instances based on the corresponding distance parameter;

    constructing one or more probe trajectories based on one or more sequences of instances of probe data identified in the plurality of instances of probe data;

    analyzing at least one of the one or more probe trajectories based at least in part on lane change probabilities to generate at least one lane level trajectory;

    determining lane level traffic information based on the at least one lane level trajectory; and

    providing a lane level traffic information notification comprising at least a portion of the lane level traffic information to at least one computing entity, the at least one computing entity configured to perform at least one navigation-related function based at least in part on the lane level traffic information.
