When were Traffic Lights Invented?
Traffic
lights
were invented in the United States and introduced in
New York in 1918. Traffic lights are used to control the flow
of traffic, determine the right of way at intersections and
give greater
safety to drivers.
Traffic lights
came to be used for the first time in Britain in 1928. Sixty years before this, the London
police had introduced a
system of
traffic control signals based on the swinging arms of the
semaphore.
