A time to collision 510 is determined between a turning host vehicle and each of a plurality of targets 505. Based on a lateral distance and a longitudinal distance, a minimum distance 520 is determined between the turning host vehicle and each of the plurality of targets. A threat number is determined 530 for each target selected based on the time to collision and the minimum distance. A vehicle component is actuated based on the threat number 535. The actuation may occur when the threat or risk number is over a threshold value. The minimum distance may be based on the velocity and acceleration of the target or the turn rate of the host vehicle. It may also be based on a predicted distance between the host vehicle and the targets over a predetermined time period. This can be used to mitigate collisions, especially at intersections.
