Displaying a red and green traffic signal and vintage black and white cars with the letters spelling “G-O-O-G-L-E”, Google celebrated the 101st anniversary of the first electric traffic signal with the special doodle, on its homepage.
The first electric traffic signal was installed in Cleveland Ohio on 5 August 1914, thus changing urban landscapes. It was developed in 1912 by Lester Wire, a policeman in Salt Lake City, Utah, who also used red-green lights. Following which, 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.
“Doodler Nate Swinehart hearkens back to an earlier time with shades of black and white, and uses the background colors to make the red and green signals particularly luminous. It’s not an artistic coincidence that the cars leap forward and screech wildly to a halt, either — the yellow light wouldn’t appear for several years, and overzealous motorists had to stop on a dime,” said the Google Doodle official website.
