Method, apparatus, and computer program product for determining lane level traffic information

An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and computer program code configured to, with the processor, cause the apparatus to at least:

• receive a plurality of probe data points, each probe data point received from a probe apparatus of a plurality of probe apparatuses, each probe apparatus comprising one or more sensors and being onboard a respective vehicle, wherein each probe data point comprises location information associated with the respective probe apparatus;
• determine a path through an intersection from among a plurality of paths through the intersection for each probe apparatus based, at least in part, on a sequence of probe data points from each respective probe apparatus;
• determine, for each path through the intersection, an average speed of probe apparatuses traveling along the respective path and an average travel time along a road link approaching the intersection of the probe apparatuses traveling along the respective path;
• calculate a differential amount of time between a highest average travel time along the road link approaching the intersection corresponding to a first path and a lowest average travel time along the road link approaching the intersection corresponding to a second path;
• determine a direction based traffic event in response to the differential amount of time between the highest average travel time and the lowest average travel time;
• publish the direction based traffic event with lane-level traffic to users;
• and
• provide route guidance relative to the intersection based on the lane-level traffic of the plurality of paths through the intersection.
