Li-Fi Based Smart Traffic Network
Aníbal Correa, A. Hamid, E. Sparks · 2018
Cities are struggling to cope with problems caused by the increased demand of roadway. In a future where autonomous cars replace our current human based traffic system, the smart traffic system is designed to allow communication between automobiles and their traffic environment. This is usually called V2X technology. Using Li-Fi, a visible light communications system, autonomous cars will be able to communicate with each other and with the traffic network to eradicate any human error that might occur while driving today. That said, this Li-Fi based system is complimentary to existing autonomous systems that cars use such as radar, LIDAR or cameras. Using light pulses at a specific frequency, an FPGA will be used to send a unique signal for every traffic light, sign and car.
