Traffic lights in use before there were motorcars
 

Traffic lights were used before the advent of the motorcar. In 1868, British railroad signal engineer J P Knight invented the first traffic light, a lantern with red and green signals. 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.

Motorcars were introduced to the US in the late 1890s and the need for traffic control soon became obvious. A number of people came up with ideas for traffic control. 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.

In 1912, Lester Wire of Salt Lake City, Utah invented an electric traffic light that used red and green lights. However, he did not apply for a patent. The next year, James Hoge received patent no 1,251,666 for a manually controlled traffic light system using electric lights. It was installed in Cleveland, Ohio in 1914, displaying the words STOP and MOVE.

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). His design could be operated manually or in automatic.

The amber light was added in 1920 by William Potts, a Detroit policeman. He actually invented several traffic light systems, including the overhang four-way system, but did not apply for patents. The first person to apply for a patent to produce inexpensive traffic lights was Garrett Morgan, who received his patent in 1923.

Parking Meter

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. His Magee-Hale Park-O-Meter Company installed the first meter in Oklahoma City in 1935 and still produces most of the parking meters in the United States.

Don't Walk

The first "Don't Walk"' signs were installed in New York City on 5 February 1952. Red remained the preferred color for warning signs because red elevates the blood pressure, heightening nervous tension, therefore the most likely color to attract attention. Yellow is used in signs aimed at vehicle traffic because it is the most visible color in the spectrum and can be seen from the farthest distance.

 I remember the first walk signals ... me and my buddy were in my 1954 MG roadster with a few drinks under our belts ... the darn thing flashed the green walk signal ... I blasted through right in front of police headquarters . Pedestrians scambling .... 2 cops blowing whistles ... and running after me ... they let me off as they did here then for a few ... after I explained how the green confused me    yea I played that poor lil innocent act ... ... not now .... now I'd be in the slammer !

I don't think I'd want to lay claim to the parking meter legacy..probably not one of the  most liked inventions in history

Several years ago my daughter ask my wife and I if it was fun to go to school when we were kids them she added you know back before people had invented cars. We had to show her pictures of cars in the 40 & 50s before she would believe it.

The last moon landing has been so long ago my kids do not believe they actually landed on the moon. I had allways taken it for granted and mentioned it in a conversation once. I had to actually convince them about it! A lot of kids in countries without space programmes hardly know about it!!!
