Smart Car Prototype to Avoid Rear End Car Collision

The number of vehicles expanded exponentially within the world in day by day. Expanding the number of vehicles cause increasing the number of passing due to car mishap which is bigger in number compared to the passing caused by sick wellbeing. Most of the car mischance happen due to rear end collision of vehicle, more than 50 or 60 % rate of mishaps detailed within the world due to rear end collision. Existing studies about rear end collision avoidance are limited to the physiological response of car drivers and use only buzzer warning or deceleration of vehicles due to braking and display the breaking intensity. These are the safety measures to maintain a strategic distance from the rear end car collision ,but it isn't admission on the genuine time circumstances may be driver and traveller gotten to be panic. Driver and traveller security is major concerns of automobiles system. In these paper we propose a effective framework to avoid the rear end collision of vehicles utilizing ultrasonic sensors. Ultrasonic sensors naturally calculate the distance of vehicle and obstacles within the front end, and automatically stop the vehicle if it is critical region. The vehicle will naturally begin until it is in secure run or else obstacles will be cleared from the rear end. The proposed strategy make a comparative study on the existing framework based on its performance.
