This paper proposes an intelligent automobile collision avoidance and safety system. The system is designed to detect an imminent crash and works on preventing or reducing the intensity of a coming accident at the rear end or front of the vehicle. The method presented here uses ultrasonic sound sensor technology. It recognizes and displays messages to the driver about the vehicles approaching his/her car. The system will measure the distance between two vehicles moving in the same lane and same direction. In case of an object trajectory is directed to its own vehicle and becomes dangerous, the system deploys safety measures to its own vehicle.
