1. A collision avoidance system adapted for use with a host vehicle, and by an operator, said system comprising:

  • at least one sensor configured to detect an object located a minimum threshold distance from the vehicle, so as to determine a detected object location;

    a map database including a plurality of intersecting links, and denoting overpass locations;

    a locator device communicatively coupled to the map database, and configured to detect the current position coordinates of the vehicle within the map database; and

    an electronic control unit communicatively coupled to the sensor, database, and device, and programmably configured to autonomously;

    execute a warning assessment algorithm,compare the detected object location with the overpass locations, so as to determine whether the detected object location is generally at an overpass location,modify the warning assessment algorithm, when the detected object location is at a general overpass location, andcause a warning perceivable by the operator to be generated, or a mitigating maneuver by the vehicle to be performed, when the execution of the algorithm detects a potential collision.
