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.
