Google Celebrates 101 Years of Traffic Light with Animated Google Doodle
Google is celebrating 101 years of electric traffic lights with animated Google doodle. The animated doodle consists of cars written with the letters spelling “G-O-O-G-L-E”, stopping at a red light waiting to pass when the light turns green.
An American policeman Lester Wire, in Utah, developed electric traffic light for the first time in 1912, using red and green lights.
Traffic signal system was first installed on5 August 1914 by an American company in the corner of East 105th Street, Euclid Avenue in Cleveland, Ohio.
Police officers had to work with the lights in hand before the invention of electric traffic lights. In 1920, to alert the motorists about the change of lights, bells were added. Amber lights replaced bells and continue to be used on the system even today.
