The History of the Traffic Signal - Abridged

Did you know that the traffic signal was initially used to regulate movements for horses and buggies? Developed by a policeman, this simple, three-color icon has endured for nearly a century with relatively little change. 

Today, the US alone has over 300,000 signalized intersections, a vast difference from the horse and buggy days. In this newsletter we cover the history of the traffic signal with a look at where it is headed in years to come.

So why does the traffic light take so long to change and why was the green light so short? This newsletter addresses these questions along with a few fun facts to help you better understand signal timing.
