1. A method for identifying a lane level traffic surprise, the method comprising:
receiving historical lane level traffic information including a representation of a speed of travel along a respective lane of a link during each time epoch of a predefined time period;
receiving recent lane level traffic information including a representation of a speed of travel along the respective lane of the link during each time epoch of the predefined time period, wherein the recent lane level traffic information is indicative of more recent traffic conditions than traffic conditions represented by at least some of the historical lane level traffic information, wherein the recent lane level traffic information is based on probe data collected by one or more probes that are traveling within a current time epoch or have traveled within a sliding time window that extends back from a current time over a predefined period of time along the respective lane of the link, and wherein the probe data is associated with one or more respective identifiers that identify the one or more probes that provide the probe data and enable linking of instances of probe data into vehicle trajectories and probe traces while maintaining anonymity of one or more probe devices associated with the one or more probes that provide the probe data;
determining a representation of a difference between representations of the speed of travel provided by the historical lane level traffic information and the recent lane level traffic information for each of the time epochs; and
identifying the lane level traffic surprise based upon the representation of the difference.
