Prevention of Road Accidents by Interconnected Vehicles Using Li-Fi Technology

Abstract

Road accidents frequently occur due to lack of timely communication between vehicles and delayed response to hazardous situations. This paper proposes an advanced Vehicle-to-Vehicle (V2V) communication system using Li-Fi (Light Fidelity) technology for real-time hazard information exchange. Li-Fi enables high-speed wireless data transmission through visible light using LEDs and photodiodes, offering faster and more secure communication than RF-based systems. Vehicles are equipped with ultrasonic sensors, accelerometers, and alcohol detectors to monitor distance, speed, obstacles, and driver condition. This information is transmitted in real-time to nearby vehicles using Li-Fi. The receiving vehicle processes data and alerts the driver through visual and audio warnings. Experimental evaluation demonstrates 95.2% data transmission accuracy at up to 8 meters range, 15ms communication latency, and 92% accident avoidance rate in simulated multi-vehicle scenarios.
