THE FIRST ELECTRIC TRAFFIC LIGHTS

In the early 1900's,the world was developing at a very rapid pace, and with the
growth of industrialization, cities became more crowded. Furthermore, with the invention
automobiles, the traffic on the roads increased significantly, so there was a need for a
better traffic system.

In 1912, an American policeman, Lester Wire, who was concerned with the
increasing traffic, came up with the idea of the first electric traffic light.Based on Wire's
design, the lights were first installed in Cleveland, Ohio, on August 5,1914, at the corner
of 105th and Euclid Avenue

The first electric traffic light had only red and green lights; it did not have a
yellow light like modern- day traffic signals.Instead of a yellow light, it had a buzzer
sound that was used to indicate that the signal would be changing soon.

In the year 1920, a policeman named William Potts in Detroit, Michigan
invented the first four-way and three-coloured traffic lights. Apart from red and green, a
third colour - amber (or yellow) - was introduced. Detroit became the first city to
implement the four-way and three-colored traffic lights. In the 1920's,several automated
traffic signals were installed in major cities around the world. The modern traffic light
still uses this famous T-shaped model with three different colors.
safest vehicles only far crossroad follow across reason

1. Due to the invention of cars, the traffic on the roads increased rapidly.
2. The first electric traffic light was invented in 1914 by Lester Wire.

5. Detroit was the first city to use the red, yellow, and green lights to control road traffic.

1. Read the passage and answer the questions.

The first traffic control device appeared near the British House of Parliament at the intersection of George and Bridge Streets. The device was made in response to the desire by a Select Committee to use railway signals on highways. The device had lights and it used arms which extended outwards. It was operated manually by a police officer. The signal was 22 feet high and crowned with a gas light. The light was called semaphore and had arms that would extend horizontally that commanded drivers to "Stop" and then the arms would lower to a 45 degrees angle to tell drivers to proceed with "Caution". At night a red light would command "Stop" and a green light would mean use "Caution". The man behind this new and different invention was John Peake Knight a railroad engineer. The main reason for the traffic light was that there was an overflow of horse-drawn traffic over Westminster Bridge which forced thousands of pedestrians to walk next to the house of Parliament. But Knight's invention was not to last long. After only a month of use the device exploded and injured the police officer who was operating the light. In the first two decades of the 20th century semaphore traffic signals, like the one in London, were in use all over the United States with each state having its own design of the device. One good example was from Toledo, Ohio in 1908. The words "Stop" and "Go" were in white on a green background and the lights had red and green lenses illuminated by kerosene lamps for night travelers and the arms where eight feet above ground. Controlled by a traffic officer who would blow a whistle before changing the commands on this signal to help alert travelers of the change, the design was also used in Philadelphia and Detroit. The example in Ohio was the first time America tried to use a more visible form of traffic control that evolved the use of semaphore. The device that was used in Ohio was designed based on the use of railroad signals.

Modern traffic lights are an American invention. Red-green systems were installed in Cleveland in 1914. Three-color signals were installed in New York in 1918. They used to be operated by hand from a tower in the middle of the street. The first lights of this type appeared in London, on the junction between St. James Street and Piccadilly, in 1925. Automa signals were installed a year later. In the past, traffic lights used to be very special. In New York, some lights used to have a statue on top. In Los Angeles, the lights did not just change silently but would ring bells to wake the sleeping motorists of the 1930s. These are gone and have been replaced by modern systems that are seen everywhere now.
