Design of precrash system for smart cars by using li-fi

Abstract

In this paper we proposed a system to avoid collision between vehicles by using light fidelity (Li-Fi) technology. The data transmission from one vehicle to another is facilitate with the help of car to car communication (C2C). The model consists of Li-Fi circuit, Arduino UNO, Ultrasonic Range Sensor, Servo Motor. The transmitter section will be placed on the rear light of the leading car and the receiver section will be placed on the front of the following car. The transmitter section placed on the leading car will sent the calculated speed to the receiver section placed on the following car and according to the data received the speed of the following car will change such that it avoids collision. The system makes use of the visible light spectrum for communication between vehicles. Hence the collision detection system become cheaper.
