There
is a lot of technology in the modern day that our society takes for granted.
Yet, all the technology we use on daily basis came from inventions created to
make life a little easier, and in some cases, safer. Today’s featured
transportation legend saw a problem that needed to be fixed and laid down the
foundation for an object most people use every day: The three-signal traffic
light.
Garrett
Morgan was an inventor who was born on March 4, 1877, in Paris, Kentucky.
After leaving home at the age of 14, he made it to Ohio and became a handyman
in Cincinnati. Later, he moved to Cleveland and worked as a sewing machine
repairman. After a few years, he was able to open his own sewing machine repair
shop.
In
the early 1920s, horse-drawn carriages, bikes, wagons, streetcars, automobiles
and pedestrians shared the same infrastructure and streets became quickly
congested. At this time, there were manually operated traffic signals at
intersections but their effectiveness left much to be desired. They switched
between “Stop” and “Go” quickly and gave drivers little-to-no warning. Without
time to react, collisions were common.
It
is said that Morgan saw a serious crash and it prompted to him to design a
three-way traffic signal to help give drivers more time and clear intersections
before traffic entered.
“The signal Morgan patented was a
T-shaped pole with three settings,” according to History.com. “At night, when
traffic was light, it could be set at half-mast (like a blinking yellow light
today), warning drivers to proceed carefully through the intersection.”

Ohio History Central’s website said that
the invention had three types of signals that said; “Stop,” “Go,” and “Stop in
all directions.” The latter signal was created to allow pedestrians to cross
the streets safely.
Morgan
sold the rights to his invention to General Electric for $40,000. He is
responsible for several other inventions, including the gas mask. He even
developed his own newspaper called the Cleveland Call.
Morgan
died in 1963 and although his traffic signal is not the same model we use
today, it is because of Morgan that we have an interim or “caution” signal that
helps clear intersections so traffic can move at a safer pace.
