Red Green
How U.S. start using the red and green light system for traffic?
Where do they come? Why did you decide to use stop for red lights, green lights to go and yellow caution lights? How to get the arrangement?
"Even during the days horse and car traffic in big cities often heavy. Police officers had to be stationed full time directing traffic at intersections very traffic. The traffic light of the world first came before the car was in use, and was only the traffic of pedestrians, strollers, and wagons. Installed at an intersection in London in 1868, was a revolving lantern with red and green signals. Red means "stop" and green meant "caution." The lantern, illuminated by gas, developed by means of a lever on the base to the right before the traffic light. On 2 January 1869, this light oil exploded, injuring a police officer is being used. With the advent of automobiles, the situation deteriorated further. Police Officer William L. Potts, Detroit, Michigan, decided to do something about the problem. What he had in mind was how to adapt the railroad signals for street use. Railroads and the use of automatic controls. However, rail traffic traveled along parallel lines. Street traffic travels at right angles. Potts uses red, amber, green and light rail and close to thirty-seven dollars worth of wire and electrical controls to make the first of 4 three-way traffic light color. Was installed in 1920 at the corner of Woodward and Michigan Avenues in Detroit. Within a year, Detroit had installed a total of fifteen of the automatic lights new. At about the same time, Garrett Morgan of Cleveland, Ohio, realized the need to control the flow of traffic. A gifted inventor and reportedly the first African American in owning a car in Cleveland, Ohio, invented the electric light auto traffic. Although it was more like semaphore signals looks at railroad crossings today. Many others had obtained U.S. patents for traffic signals, some as early as 1918. But the patent was bought Morgan by General Electric Corporation and provides protection they need to start building a monopoly in the manufacture of traffic lights. "" 1. As for color red, I remember reading about studies for almost 100 years that red is brighter than the first color to be recorded in our nerve endings of the retina. Therefore, for people without color blindness, bright red catches the eye faster – hence the traditional use as the universal color of fire, safety, danger, and perhaps traffic lights. "

Red Green’s Hindsight Is 20/20 - $14.99 Eleven years before the first episode of The Red Green Show, Red Green (Steve Smith) made his first television debut during a two-minute guest appearance on a 1979 variety show. Red Green: Hindsight Is 20/20 looks back at the 25 years following that appearance, and takes pains to recount Green’s knack for wreaking havoc on what are supposed to be the most flawless of plans. A variety of Possum Lodge regulars show up to reminisce about Red’s most memorable moments, and never-before-seen Red Green footage filmed before the series aired on television is also featured. ~ Tracie Cooper, Rovi |
