Highway Navigation System Using Li-Fi

Abstract

Light is present everywhere as street lamp and traffic light. Imagine that all these light bulbs are high speed wireless transmitter that connects either human to human or systems with systems. In recent times the using of internet is rapidly increase which leads to radio waves being widely used. Long distance data transmission makes use of this spectrum. It has become difficult to keep up with the demand for the high speed connectivity as the number of users is increasing. An alternative and advantageous replacement can be visible light communication (VLC).In this paper, Li-Fi technology is used to build the highway navigation system. The Li-Fi technology based on the visible light communication and it is one of the applications of VLC. Frequently we have to navigating one place to another place. The major issues faced by drivers are navigating at night. Low battery of mobile phone or network connectivity issues are the major problems to use the Gmap. This paper proposes a system which aims to provide efficient and secure communication between vehicles and the street light .To improve safety and reduce accidents in roads at night we are using this system .In this system, LED lights embedded in the highway street light that act as a data transmitter and the receiver are installed on vehicles like car, truck to receive and process the data without using internet. The received information is then displayed on a display screen in the vehicle, such as current location and future diversions. This system is alternate solution for the road navigation board system. In this system the Arduino UNO is used in the transmitter and receiver portions, and it is programmed using the Arduino IDE. The overall the highway navigation system using Li-Fi technology to improve traffic safety and efficiency while reducing the environmental impact of transportation.
