Designed by Yanko this traffic light seems like a more efficient design. Using a sand glass design can relieve some anxiety to the people waiting at the light. It can also help for fast speed roads were people may have to slam their brakes when the light turns red. A large display like this will make it obvious to drivers when to go or stop.
There is much controversy about it. Some people say, “the traffic lights are working just fine, why change.” Others say that color blind people will be confused. This can easily be solved by the placement of the lights just like the placement of the current light system. I personally think that this is safer and more efficient. I know of so many times where the speed limit is 50 and there is a traffic light at the end of a steep hill. During winter I get so scared that I won’t be able to stop so I go really slow down the hill. With this design I would be able to see from far away how much longer the light will be green so I can judge my speed accordingly. If you think about it, it helps us slow down when we need to, similar to this device from RatedRadarDetector. Nevertheless, I only see the design working for selected locations.
