History And Invention Of The Stoplight, is today’s post here in Discover My Inventions, the traffic lights is also known as traffic signals, ( OR RED LIGHTS ), and traffic lamps, traffic semaphore, signal lights, stop lights, robots (in South Africa), and traffic control signals (in technical parlance), are signalling devices positioned at road intersections, pedestrian crossings, and other locations to control flows of traffic.
The world’s first, manually operated gas-lit traffic signal was short lived, Installed in London in December 1868, it exploded less than a month later, injuring or killing its policeman operator. Traffic control started to seem necessary in the late 1890s and Earnest Sirrine from Chicago patented the first automated traffic control system in 1910, It used the words STOP and PROCEED, although neither word lit up.
In London England before the traffic lights the police controlled the flow of traffic, a well-documented example being that on London Bridge in 1722. :3 Three men were given the task of directing traffic coming in and out of either London or Southwark, each officer would help direct traffic coming out of Southwark into London and he made sure all traffic stayed on the west end of the bridge, a second officer would direct traffic on the east end of the bridge to control the flow of people leaving London and going into Southwark.
Here in the US it was’nt untill 1923, Garrett Morgan patented an electric automatic traffic signal. Morgan was the first African-American to own a car in Cleveland. He also invented the gas mask, Morgan sold the rights to his traffic signal to General Electric for $40,000, the stoplight is created for safety and to give everyone an equal chance while driving through CDs intersections and turnoffs, traffic lights always been put were traffic is the heaviest.
