The credit for taking all your parking credits goes to Carlton Cole Magee who invented the first parking meter in 1932, receiving a patent (no 2,118,318) for it in 1935. The first person to apply for a patent to produce inexpensive traffic lights was Garrett Morgan, who received his patent in 1923. He actually invented several traffic light systems, including the overhang four-way system, but did not apply for patents. The amber light was added in 1920 by William Potts, a Detroit policeman. His design could be operated manually or in automatic. The first traffic light system to use red and green lights were patented by William Ghiglieri of San Francisco, California in 1917 (patented no 1,224,632). It was installed in Cleveland, Ohio in 1914, displaying the words STOP and MOVE. The next year, James Hoge received patent no 1,251,666 for a manually controlled traffic light system using electric lights. In 1912, Lester Wire of Salt Lake City, Utah invented an electric traffic light that used red and green lights. In 1910, Earnest Sirrine of Chicago, Illinois filed for a patent (no 976,939) for what is considered the first automatic street traffic system, using non illuminated words STOP and PROCEED. A number of people came up with ideas for traffic control. Motorcars were introduced to the US in the late 1890s and the need for traffic control soon became obvious. It was installed at the intersection of George and Bridge Streets in front of the the British House of Commons to control the flow of horse buggies and pedestrians. In 1868, British railroad signal engineer J P Knight invented the first traffic light, a lantern with red and green signals. Traffic lights were used before the advent of the motorcar.
