Small-Scale V2V-VLC for Enhanced Road Traffic Safety

In the context of global research aimed at enhancing data transfer rates and efficiency, light emerges as a cost-free and unregulated asset that has the potential to revolutionize communication technologies. The complete replacement of conventional lighting with LEDs led to the development of a novel optical communication system. Visible light communication (VLC) uses LEDs as transmitters and photodetectors or image sensors as receivers. The technology has significant potential for a range of applications, especially in intelligent transport systems (ITS). In this context, the headlights and taillights of vehicles can transmit different types of information to other vehicles, enhancing traffic safety and ultimately preventing fatalities on the road. The paper proposes a small-scale vehicle-to-vehicle ITS that uses robot-type cars that are equipped with emission and reception modules. The cars transmit various information using VLC to implement a variety of events, including emergency braking, deceleration, left or right turns, and engine on/off, all of which are essential for road traffic safety. The maximum distance between vehicles that ensures successful data transmission will also be determined.
