ABSTRACT:
A system and a method avoids the collision of a vehicle with animals tending to cross the road before the moving vehicle. Such system comprises a visual system directly actuating a RF emitter, or more RF emitters, emitting directional sound waves with a frequency above 25,000 Hz. Sound waves are directed frontally though with a frequency decreasing from the center of the roadway towards the road edge, so as to lead the animal to move towards the road edge.
