A final year Physics student of the Kwame Nkrumah University of Science and Technology (KNUST), Bruce Christopher Konu, has built a single source traffic light system. What happens is that all the three colour signals red, yellow and green will come from one source, with some of the long-term benefits being reduced production and maintenance costs.
Traffic signals complement human wardens to ensure adherence to safety regulation on the roads. In their absence, a lot of inconvenience is caused – sometimes ending in the loss of human life, so, Bruce Konu took to the laboratory in order to work on cost- effective ways of building and repairing traffic lights.
Speaking on his motivation, Bruce said “When the traffic light runs into trouble you have to go through the trouble to repair all the phases. So I contacted my supervisors, Dr Reuben Tamakloe and Dr Michael Donkor and informed them of LEDS which give off all the three colors”.
The signal operation is based on the RGB (Red, Green, and Blue) color mode which represents the initials of three primary colors.
The lights are then fused together in various ways, in order to reproduce a broad array of colors.
“With this one, cost is reduced by three and maintenance is also reduced by three,” he emphasised.
The single phase traffic light is equipped with a GSM chip which reports on the status of the machine; making it possible to use your phone to shut it down or power it up from any part of the world.
Malfunctioning traffic lights remain a major concern, especially among road users due to the danger they pose to public safety. Should this technology get picked up by the relevant state institutions and even private individuals, it’s quite possible we’ll have more locally engineered and produced traffic lights at vantage points in our city and town streets.
