Abstract
AUDISAFE is an accident preventive device which allows a driver to perceive the nature, the intentions, the distance, the relative speed, and the direction of motion, of potential impending hazards in one simple, unambiguous signal. It is particularly useful in conditions of low visibility. The driver's auditory system is as much an integral part of the device as the electronic hardware. The system is designed to be of use in 15 common accident-contributory situations. The device has additional applications in traffic control, and in areas outside the field of road transport.
