System Traffic

What began in the United States using the lighting red / green traffic?
Where is he? Why did they decide to use red light for stop, green lights and yellow lights to go for caution? How did they arrive at the agreement?
"Even during the days of horse and buggy traffic in big cities was often heavy. Police officers should be stationed on time lots of direct traffic at busy intersections. The traffic light of the world first came before the automobile was in use, and traffic consisted only of pedestrians, strollers, and wagons. Installed at an intersection in London in 1868, it was a revolving lantern with red and green signals. Red means "stop" and green means "caution." The lantern, illuminated by gas, has been transformed by a lever at its base to the appropriate light faced traffic. On January 2, 1869, the traffic light crude oil, exploded, injuring the policeman who was using it. With the advent of the automobile, the situation has worsened. Police Officer William L. Potts of Detroit, Michigan, decided to do something about the problem. What he had in mind was to find a way to adapt the signals from railways to the road. The railways were already in using automatic controls. But rail traffic traveled along parallel lines. Street traffic traveled at right angles. Potts used red, amber, and green lights and railroad thirty-seven dollars of orders for electrical wire and make the first 4-way three color traffic lights. It was installed in 1920 at the corner of Woodward Avenue and Michigan in Detroit. In one year, Detroit had installed a total of fifteen new automatic lights. At about the same time, Garrett Morgan of Cleveland, Ohio, realized the need to control the flow of traffic. A gifted inventor and would have the first African American to own a car in Cleveland, Ohio, he invented the electric fire automatically. Although it was more like semaphore signals to see you in passing the train today. Many others have received U.S. patents for traffic signals, some as early as 1918. But the patent was bought by Morgan General Electric Corporation and provided the protection they need to start building a monopoly on the manufacture of traffic lights. "" 1. Concerning red, I remember reading about studies almost 100 years ago found a bright red color to the first record on our endings nerve of the retina. Therefore, for those without color blindness, red attracts the eye fastest – hence the traditional use as Color Universal fire, safety, danger, and traffic lights may be. "
