This day in history: The first electric traffic signal is installed in Ohio

We tend to take traffic signals for granted, but they are a vital and very complex system that keeps everything running with no accidents.

The first ever electric traffic signal was introduced in Cleveland, Ohio, at the corner of Euclid Avenue and East 105th Street on August 5, 1914.

It's been 101 years since we developed the system that was exported and adopted across the globe, and without it we could not function in our daily routines when it comes to transportation on crowded roads.
