Car Anti - Collision and Intercommunication System using Communication Protocol ( A Prototype Model )

Road safety has been an important concern in the world over the past few years since millions of people die every year because of car accidents and many more are injured. The wireless communication technologies enabled vehicles on a highway to communicate in order to share vehicle state information and information to avoid potential collision. Here, a protocol which avoids vehicle accidents is discussed. The vehicle state information is being obtained, using ultrasonic sensors, to predict potential accident and accordingly, reduces the vehicle speed. This protocol provides warning message when the distance is reduces than the safety limit. Here, the car is equipped with an ultrasonic sensor, which will continuously tracks for any obstacles from the front side. If the obstacle is detected, then the microcontroller will continuously compare the distance given by the ultrasonic sensor. If the distance goes on reducing indicating that, the front car is coming closer to the current car then the microcontroller program will start reducing the speed until the distance is within safe limit. A prototype model will be developed and tested against actual parameters on the road.
