Traffic At Intersection Is Regulated
The first electric traffic light ensured that traffic was regulated in Cleveland at the intersection of East 105th Street and Euclid Avenue. The traffic light itself was not a new invention, however, as the world’s first traffic light was put into operation in December 1868 London the world’s first traffic light was put into operation. It was located in Parliament Square and was gas-powered. However, this traffic light did not last long, because after a short period of operation it exploded.
Traffic Light Takes A Break
After that, there was a break for the traffic lights for a while and only after the more and more spreading of the electric light in many big cities of this world, the traffic lights came back into use, so that the traffic could be regulated better. The first electric traffic light in Cleveland, however, had only two lights at that time, one red and one green. The yellow light did not exist at that time and instead of yellow, a bell made sure that the road users were informed that the color was about to change. But this with the bell turned out soon as useless because more and more cars came on the road and with the volume, the bell was then hard to be heard.
The Traffic Light Comes To Europe Later
The electric traffic light came to Europe a little later. Eight years later, to be exact. First, the traffic light was used in Paris in 1922 and then in Hamburg. In Berlin, the electric traffic light was introduced in 1924, and from there it triumphed all over the world. Road traffic without traffic lights would be hard to imagine today, especially in the big cities of the world.
