Abstract

Objectives: Many vehicular accidents take place in India which are primarily due to lack of traffic discipline. Our aim is to minimize the accidents by creating an efficient communication system. Methods/Statistical Analysis: In our proposed system, we have used light as the carrier to create a fast and reliable communication system where OOK modulation technique is used, unlike other systems where RF is used. The LED’s are positioned in the headlights and taillights of the car which also contain the photodetector to receive light signal. The circuitry have designed and simulated in PROTEUS. Findings: It was found that by replacing all the windows of the car with BIPV, the system can run independently. Theoretically it can work up to 20m with a low bit error rate and this can be achieved by using an array of LED’s or increasing the intensity of the LED. It was observed that by hindering the intensity of the LED, the range decreased and hence the validity of the relation between Intensity of LED and range was established. It was found that the data from individual cars were being transmitted immediately with no delay. It will help conserve energy and also act as a builtin glass for the vehicle thus allowing sufficient sunlight to enter. Application/Improvements:This system can be used for vehicular communication to detail about speed, position and traffic. In the future, automatic braking and intelligent synchronization can be implemented.
