ABSTRACT

The number of vehicles in transportation system are widely increasing; so it has been a major concern for highway authorities and in cities to facilitate effective control of traffic for collision avoidance. For several highways these demands cannot be fulfilled by extending the existing roads and the current infrastructure .There is a growth in number of vehicles and with narrow roads it becomes very difficult for the driver to drive the vehicle. For even a fraction of time if driver misses his attention then it might lead a crash with the front vehicle, even if the vehicle is at a small speed. In congested traffic sometimes the vehicle owner get frosted and he can’t keep the focus or watch on the vehicle in slow moving traffic. In such a situation this pre crash vehicle detection system proved to be an excellent system from preventing a crash. Pre-crash system is a system designed to help prevent rear‐end collisions with vehicles which are stationary / travelling in the same direction. Several studies have shown that driver distraction, carelessness or inattentiveness is a factor in majority of rear end accidents. The systems objective is to alert the driver of an imminent rear end collision both at low speeds, typical of urban driving, and at higher speeds typical of rural roads and highways. Pre-Crash systems detect the possibility of collision and reduce the speed of vehicle thus playing a very important role in avoiding the collision.
