Abstract: Vehicle-to-Vehicle (V2V) communication plays an important role in improving road safety and reducing accidents. Most existing systems use wireless technologies such as Wi-Fi and Bluetooth, but these technologies sometimes face limitations such as signal interference, limited bandwidth, and reliability issues in dense traffic environments. To overcome these challenges, this project explores the use of Li-Fi for vehicle-to-vehicle communication. The proposed system demonstrates a prototype consisting of two vehicles (Bus A and Bus B) built using Arduino boards. In this system, light signals are used as the communication medium. Bus A transmits information through a high-intensity LED light, while Bus B receives the transmitted signal using a solar panel that converts light variations into electrical signals. The received information is processed and displayed on an LCD screen for the driver. Four push buttons are used in Bus A to transmit different road safety messages such as "Road Closed", "Accident Ahead", and "Stop". Bus B receives these messages and displays them on its LCD. Similarly, Bus B can also transmit messages back to Bus A, such as "I want to overtake", using the same Li-Fi communication method. Additionally, an ultrasonic sensor is integrated in Bus B to detect the distance between vehicles. If the distance becomes too small, an alert message "Do not stop suddenly - vehicle too close behind" is transmitted to Bus A. The main objective of this project is to demonstrate that Li-Fi based communication can be a promising alternative for vehicle communication systems. Since Li-Fi uses visible light for data transmission, it offers advantages such as higher data security, minimal radio frequency interference, and the possibility of long-distance communication using high-intensity light sources. The developed prototype successfully shows how Li-Fi can be applied in intelligent transportation systems to improve driver awareness and road safety.
