1. A method for collision threat assessment when a host vehicle is turning left or right at an intersection, said method comprising:

  • determining if the host vehicle is likely to turn left or right at the intersection with a predetermined level of confidence;

    segmenting the intersection and surrounding area into a plurality of different regions where each region has a different level of collision threat risk if the host vehicle is likely to turn left or right at the intersection;

    obtaining speed, velocity and position data of the host vehicle;

    obtaining speed, velocity and position data of one or more remote vehicles and/or other objects in or near the intersection;

    determining a predicted path of the host vehicle based on the speed, velocity and position data as the host vehicle travels through the intersection for each of the different segmented regions;

    determining a predicted path of one or more of the remote vehicles based on the speed, velocity and position data as the one or more vehicles travel through the intersection;

    determining whether the host vehicle and the one or more remote vehicles will simultaneously occupy a collision zone in the intersection based on the predicted path of the host vehicle and the predicted path of the one or more remote vehicles; and

    issuing a warning to a driver of the host vehicle if the host vehicle and the one or more remote vehicles will occupy the collision zone during the same time.
