Garrett Morgan See website: http://inventors.about.com/library/inventors/blgas_mask.htm ---- The world's first traffic light was operating in London, England, even before cars were invented. It was a revolving gas-lit lantern with red and green signals, but in 1869, the light exploded, injuring the policeman who was operating it. In the early 1900s Garrett Morgan, an African-American living in Cleveland, Ohio, developed the electric automatic traffic light, originally based on a semaphore-system. Shortly after this, Detroit police officer William L Potts developed the first 4-way three colour traffic light using red, amber, and green railroad lights.
No he invented the automatic oil cup and lubricator.
A "signal plan" is typically a document that outlines how signals are used or managed, whether in traffic control or communication systems. It specifies signal timings in traffic or signal allocation in communication networks.
Garrett Morgan invented the traffic light in the early 1920s while he was living in Cleveland, Ohio. His design aimed to improve road safety by introducing a system to control the flow of traffic at intersections. Morgan's innovation came as a response to the increasing number of vehicles on the road and the need for better traffic management. His traffic signal featured a three-position system, which included a warning signal, an innovation that significantly contributed to road safety.
it was invented on 1888
the first traffic light was invented in usa i didin't know who invented it the first traffic light was not automatic someone is controling it that what i all know about the trafffic light i don't know who invented the gas mask
Traffic signals were invented by Garrett A Morgan in 1923.

GARRET MORGAN
Garret Morgan
he invented the traffic signal back then because to many people were getting hurt
No he invented the automatic oil cup and lubricator.
The traffic signal invented in Jamaica is known as the "Jamaican traffic light." It was designed by Jamaican engineer and inventor, Dr. William C. "Bill" Edwards, in the 1960s. This innovative traffic light incorporated features aimed at improving road safety and traffic flow in urban areas. Its design has influenced traffic management systems in other countries as well.
The three-way traffic light was invented by Garrett Morgan in 1923. He patented the design for the T-shaped traffic signal that included a mechanism to control traffic flow at intersections.
The first inventor was Garret A. Morgan at around 1923.
A police office named William Potts of Detroit Michigan in 1920 invented the traffic signal. His race is not mentioned.
Garrett Morgan was in his early thirties when he patented his version of the three-position traffic signal in 1923. He modified the existing traffic signal design to include a warning position, improving safety and efficiency on the roads.
The four-way traffic light, also known as the modern traffic signal, was invented by Garrett Morgan in 1923. Morgan was an African American inventor and entrepreneur who patented his design to help improve road safety and reduce traffic accidents.
