When was the first traffic light installed? Traffic light’s 101st anniversary celebrated
Today’s Google doodle depicts the first electric traffic lights which were installed 101 years ago. Read our fun facts to find out where and by whom they were placed
They are the bane of impatient motorists and are responsible for thousands of road rage incidents across the globe.
Now the humble traffic light has been honoured with a Google Doodle to celebrate its 101st Anniversary on Wednesday:

The first ever traffic lights were unveiled in London in the late 19th century, and placed outside the Houses of Parliament.
Non-electric and gas-operated, police officers had to work the lights by hand in a bid to control vehicles crossing on nearby Bridge Street, Great George Street and Parliament Street.
The project was short-lived after an explosion in 1869 when a leak in gas lines passing under the device exploded, and seriously injured the police officer operating the lights.
More than thirty years later an American enjoyed greater success with some electronic lights that focused on a similar – and now internationally recognisable – system of red and green lights.

Lester Wire, a former detective in Salt Lake City, came up with the revolutionary idea in 1912, and traffic lights began springing up across the United States shortly after.
He was not the only American to come up with the idea. Garrett Morgan, an inventor from Ohio, vowed to improve traffic safety after witnessing a serious accident on the roads.
He applied for a patent for a man-powered traffic control device using a crank in 1922, but his invention is said to have never reached the prototype stage.

It has been speculated that local authorites were relucant to invest in a man-powered set of traffic signals because it would require cities to hire someone to staff it all day – whereas the emergent electric lights seemed far cheaper in comparison.
The doodle depicts the world’s first electric traffic light to be installed and put into major use in Clevland, Ohio, on August 5 1914.
Time since the first traffic light was installed
Placed on the corner of Euclid Avenue and East 105th Street, it would have been a chaotic affair, with bicycles and cars as well as horses competing for domination of the road.
Doodle illustrator Nate Swinehart said that he did not include the yellow light outlining as they were not introduced until later to regulate the traffic more effectively.
In 1920 bells were added to traffic light systems to alert motorists when the lights were about to change – they were later replaced with the amber light now seen on all traffic light systems today.

It wasn’t until 1990 that countdown timers were introduced, allowing pedestrians to judge whether there is enough time for them to cross the road before the lights turn red.
Perhaps the most impressive traffic light specimen ever to be unleashed on the world’s streets was the Traffic Light Tree, created by French sculptor Pierre Vivant in 1998.
The imposing eight-metre tall tree consists of 75 sets of lights and has become a favourite spot for tourists in London.
These days, traffic lights are highly sophisticated, incorporating special light symbols for bikes, trams and buses. Some also feature signals that are interruptible, giving priority to emergency vehicles via transmitters that send radio waves, infrared signals, or strobe light signals that are received by a sensor on or near the traffic lights.
While most countries have become dependent on traffic lights over the decades, some places are happy to do without them. In Ethiopia’s capital Addis Ababa, a huge intersection runs smoothly without a single traffic light.
