The Electric Traffic Lights completes 100 years today! Thank God for inventing them in 1914.


The first electric traffic light, on 5 August 1914, the American Traffic Signal Company installed a traffic signal system on the corner of East 105th Street and Euclid Avenue in Cleveland, Ohio.

As the countries were going chaotic because of the unorganized traffic consisting of Motor cars, horses, pedestrians and bicycles, they needed something to reduce the number of accidents and confusions. Finally in 1914 a handmade, manually operated  signal with two lights-red and green was installed and became the first savior of America’s traffic. It had also got a buzzer to indicate the light change. The first four-way, three-color traffic light was then created by police officer William Potts in Detroit, Michigan in 1920. Today, the traffic lights are highly programmed and not manually operated anymore. We may see more smarter traffic signals in the future which will automatically acquire information about the position, speed and direction of vehicles received from a hub computer. This is really fascinating.

Different countries have different kinds of traffic signals and rules but if a red light hits the signal, everyone stops! Though there are more than one types of traffic signals today, but we are really thankful for this piece of invention.
