History Behind the Traffic Signals....

Hi all !

We all seen that on the road when moving in an automobile, the red color light stops us, yellow gives us a caution and then the green makes us to go....

It is common almost all over the world. Right ???

Okay...from where the traffic light idea came?

The origin of the green, yellow and red color scheme for traffic lights is having a history and which came from rail road signaling system.......!!!!

What...??? from rail road signalling system..???

Yes...ofcourse it is...!

At initial stages, railways used red for stopping as it denoting danger since long time and green for caution, then white for go.

Ohh....it is different from what we use, right.....but they had a justification for the change we have now....!!

After some days, the white color was turned out to cause an accident and got changed into green and for caution, yellow was chosen as it is different from the other two colors.

Then in 1860s, this method was implemented for road transports and ran successfully.

The year is conform but the exact country or city in which the system got implemented for road transports is being controversial as too many cities claiming the same......so let it aside...!
