An emerging technology Li-Fi, or light fidelity is a bidirectional and fully networked wireless communications medium which uses light from light-emitting diodes (LEDs) and provides transmission of data through illumination by sending data through a LED light bulb that varies in intensity faster than the human eye can follow. It can provide connectivity within a very large area with more security and with higher data rates and high speed than data that can be transmitted through Wi-Fi. It uses visible light communication or infra-red and near ultraviolet spectrum which works by switching bulbs on and off within nanoseconds. By using Li-Fi technology highly reliable vehicle to vehicle communication is possible by transmitting and receiving data through LED head-lights and tail-lights. In this paper we propose a system that uses Li-Fi enabled LED head-light, tail-light and traffic signal light that can be used for traffic management and road safety by using vehicle to vehicle data transmission The aim of designing this system is to reduce road accidents and managing traffic more accurately.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
