1. A method of assisting operation of a vehicle, the method comprising:
obtaining, by a processor associated with the vehicle, a current object location derived from one or more sensors onboard the vehicle;
determining, by the processor, a current value for a deviation metric associated with the current object location based on a relationship between the current object location and a preceding object location derived from the one or more sensors at a preceding sampling time;
classifying, by the processor, the current object location into a respective one of a plurality of different classifications based on the current value for the deviation metric, the plurality of different classifications including a primary subset of object locations having respective values for the deviation metric less than a first threshold, wherein classifying the current object location comprises:
classifying the current object location into the primary subset when the current value for the deviation metric is less than the first threshold; and
classifying the current object location into a secondary subset of object locations when the current value for the deviation metric is greater than the first threshold, the secondary subset of object locations including one or more respective object locations having respective values for the deviation metric greater than the first threshold; and
monitoring, by the processor, a predicted vehicle path with respect to one or more object locations of the primary subset to generate an alert when the predicted vehicle path intersects the one or more object locations.
