Abstract
This paper has explored an effective monitoring of Red, Green and Yellow colors using visible-light communication systems (VLC) as a backbone on traffic lights for easy detection of traffic control light colors in South Africa as well as African continent in context to the problem of consistency in the ON state of traffic control lights. The variable frequency information of detected colors is employed to determine their state for prompt response to the road users. The lifespan of each light emitting diode (LED) dies gradually due to constant heat in the ON-state thus leave some traffic lights not attended. This negligence is because of weak network monitoring techniques which result in vehicle-to-vehicle accidents (V2V), vehicle-to-pedestrian accidents (V2P) and vehicle-to-motorcycle (V2M) accidents. The researchers deploy a TCS3200 pixel color sensor to monitor the lifespan of each LED color in the traffic light and using their variation in frequency to yield the LEDs lifespan, linking them with one central network for display. This experiment guarantees the road users of a steady traffic light to regulate the passing of vehicles without any accident both in frost, high winds and raining season.
