The first Electric Traffic Light

The impact of the electric traffic light in 1912 was to the benefit of the drivers of the time.    Before electric traffic lights there were a lot of confusion on who had the "right away."  It also let police and fire station able to control in case of an emergency.  This was a big impact because it would limited the number of accident.

The inventor of the Fist Electric Traffic light was James Hoge.  

Today we have three lights instead of only two.  Red, yellow, and green.  Today we use more technology to control signals.  They use a technique called inductive loop.
