Sometimes the drivers may become fatigue and they lose the control over the vehicle and sometimes the accidents occur due to drunken drivers and sometimes due to rash driving. In all these cases the accidents occur because the brakes are not applied at right time. Accidents There are many systems like air bags, GPS, robo driven cars, tracked cars etc which can avert accidents to some extent. But they are not much effective and hence loss of lives is continuing. REASONS FOR ACCIDENT  Ignoring traffic rules  Drunken driving  Dream driving  Mechanical failures in the vehicle  Mistakes of the drivers Vision Braking distance of a vehicle for a particular speed is the distance at which the vehicle comes to a halt from the current speed from the point of application of the brakes. Here the speed of the vehicle is sensed and the corresponding braking distance is calculated using a microcontroller. The distance of the obstacle in front is also sensed. The microcontroller compares the two distances. If the distances are within critical limits, the microcontroller activates the brakes and slows down the vehicle or brings the vehicle to a halt before the obstacle thus avoiding the collision FACTORS CONSIDERED o Braking Distance  Distance of obstacle in front Braking Distance Braking distance = V2 /2µg m Where V- Velocity of the vehicle(m/s) µ-Coefficient of friction of the road=0.8 g-acceleration due to gravity=9.81m/s2 Distance of Obstacle in Front The distance of any obstacle, a parked or a moving vehicle, a road block, a tree in the roadside, is sensed using an Ultrasonic sensor and it is fed to the microcontroller INSTRUMENTS Hall sensor Ultrasonic distance sensor Microcontroller kit Braking motor
