Abstract

With the appearance of autonomous cars, an infrastructure-to-car communication system can be easily developed by using the visible light communication (VLC). The red and green lights play an important role in the safety of road traffic, being the most significate colors of the traffic light system. The role of the proposed system is to obtain automatic braking if the traffic lights are red and an audio warning in the case of yellow color by modulating the radiation emitted by the traffic light to transmit a code for each of red and yellow lights. A secondary solution is proposed which avoids the modification of the current infrastructure of the traffic light system by adding a supplementary light emission element. The element consists of an infrared emitter used to send either the red color code or the yellow color code depending on the illuminated traffic light.
