Abstract

Objectives: This paper ensures to enhance the quality of Intelligent Transportation System by combining the technologies of GPS and Li-Fi to provide an effective vehicle communication and protection between the fleet of vehicles. Using Li-Fi the data stream is transmitted in form of bits through visible light. Methods:A low power microcontroller TI MSP430F5529 is interfaced with Li-Fi module through which data such as speed and direction of vehicle is transferred between the leading and following vehicle. In case of vehicle goes out of range, the location of the vehicle is informed using GPS and GSM technology to the leading vehicle and the base station. This Li-Fi communication happens between the vehicles at high speed while the urgent messages can be transferred through the GSM module which overcomes the RF band limitation. Findings: In our prototype the usage of LEDs yields high speed data transmission, improves energy savings and requires less maintenance and also the Li-Fi technology is safer as it eliminates the harmful radiation intrusion. High directional communication ensures good message integration with ideal reachability and reduced latency.Applications:As the designed module combines the illumination, communication and tracking purposes together, the operating costs of the vehicles is highly reduced. Our prototype will provide a reliable and an eco-friendly solution which enables people to enjoy high end technology at an economical rate.
