Google doodle 101th Anniversary of
the First Electric Traffic Signal System
Hello again. Today Google celebrates the 101th Anniversary of the First Electric Traffic Signal System with a creative interactive doodle. The letters 'Google' appear when the cars stop on red signal. Amazing doodle.
Some information?
On August 5, 1914, the American Traffic Signal Company installed a traffic signal system on the corner of East 105th Street and Euclid Avenue in Cleveland, Ohio.
It had two colors, red and green, and a buzzer, based on the design of James Hoge, to provide a warning for color changes. The design allowed police and fire stations to control the signals in case of emergency.
As for the yellow light we all take for granted, it did not appear until Detroit police officer William Potts came up with the idea in 1920.
Another Clevelander, Garrett Morgan, patented the three-position traffic signal that we all know so well today.

That reminds me how I must leave town and traffic to enjoy my holidays. Something different. Going to the beach -it's a good start - relaxing reading, some interesting concerts with family and friends. Soon.
Now, let's back to the reality ! As well, at the end of every month I put together a list of the most popular posts of June.
