Abstract: The present invention relates to a method and apparatus employing techniques of computer vision and deep neural networks to provide audible and visual warning indications to vehicle drivers and bicycle riders to reduce the probability of a collision between the vehicle and the bicycle to which it is mounted, particularly in the case of distracted driving. The present invention amounts to an additional set of eyes that is ever-alert and dedicated to watching for impending collisions from behind or from directions not in the operator's primary field of view. When such a potential collision is detected, the present invention provides audible and visual alerts to gain the attention of drivers and riders to reduce the possibility of collision.
