Traffic Light PicturesWhen you walk, whether walking, riding a bicycle, in a car, or any other vehicle, you must obey a red, yellow, and green object. This object that all road users must obey to avoid chaos when they use the road. Almost all places in all cities see traffic lights whose colors have become a global agreement. It is red to stop, yellow to be careful, and green to go back. Do you know where traffic lights were first used? There are also traffic lights that differ in color from other countries.The World’s First Traffic Light Traffic lights help regulate the course of vehicles and other road users so as not to collide with each other.Traffic lights were first installed in the city of London to break down the traffic jams that occurred in the city of London at that time. Heavy traffic makes it difficult for pedestrians, especially when dealing with crossroads. If left unchecked will cause traffic jams and accidents.On December 10, 1868, 151 years ago, the first traffic light was introduced to regulate crossroads. A traffic light is installed near the British parliament building in Westminster. It was regulated traffic between the crossroads between Great George Street and Bridge Street.The traffic lights at that time were very different from today’s traffic lights. Traffic lights were in the form of an officer who is 20 feet tall and is posing for directions with his hands. His big hands stretched out 90 degrees by using red lights, which means stop. At that time, the yellow light had not been introduced to the public. The hand-ignited green light stretches 45 degrees. Traffic lights work by using gasoline to drive automatically.Then the first traffic light was created by John Peake Knight, an engineer and a train manager. He had worked on designing a signaling system for the railway network in England. From his experience in the railways, in 1865, he became a commissioner of the London Police. Knight tried to apply the railway signaling system to the highway.46 years later, the modern traffic light was created. In her book How the Automobile Changed History, Diane Bailey says that a crossroads between Euclid Avenue and East 105th Street in Cleveland, Ohio, United States, in 1914 was where the world’s first modern traffic light appeared.Fun fact: traffic lights in Japan use blue to replace green. It because they don’t have green in Japanese. Green in Japanese, “Midori”, appeared after the 8th century.
