Back in around 1960, in the last few seconds of the red light before it changed to green, the yellow light came on, so drivers could shift their manual transmissions into gear and be ready to go. Also, near the end of the green light cycle, the yellow light then came on. The yellow and green were both on at the same time. Sometimes in small towns, the go light was blue. My Uncle Cap told us kids, there was a little man who lived inside the signal, who changed the lights and Santa brought him new light bulbs on Christmas
The US traffic light system needs a MAJOR overhaul. I appreciate how the video mentioned lights works in tandem, and although they do at intersections, there are many lights along a street that do not. The outcome? Red light after red light after red light... We need smart traffic light systems that work in a network, going beyond what was described in the video. (Thanks for the info, by the way!)
Emergency vehicles don't have a remote control. They have a strobe on the vehicle that is not able to be seen by the naked eye, but is picked up by a sensor on the mast arm or span wire of the traffic signal. That sensor then tells the traffic signal controller to put the cross street into a red phase, allowing the emergency vehicle to safely pass through the intersection.
In my country, green means honk your horn as loud as you can and be an asshole, yellow is to go faster to reach the intersection before it turns red, and red means go if there are no enforcers to see you.
Unfortunately people who operate traffic lights still get very wrong, allot of traffic signals aren't synchronised with each other especially on long continueses roads.....
They are far behind proper traffic light efficency. The city planners and engineers agree to make the road lights as inefficient as possible in order to create "compunded stresses" on the roads.
Running a yellow light could be reduced if drivers were educated correctly on the road rules. You must stop on a yellow light if it is safe to do so. Anyone speeding up when they clearly could and should be braking scores themself a $1,000 fine.
I disagree with the end of traffic lights. They never ever should've come out with self driver less cars in the first place. They don't even know what's going on.
_In the 20th century:_ *Traffic lights* were automated _In the 21st century:_ *Cars* are automated _In the 22nd century:_ *Humans* will be automated?.... xD I can't sleep at nights haha
@@its_anonymous1289 no we wont . Only the stupid sheep who do whatever somebody they dont even know says . Even if they say it from 1000 miles away . They will run in line and shoot somthing in their blood stream that they have no clue how many chemicals are there within that needle
Garret Morgan didn't invent THE traffic light. He invented A traffic light. His 1922 invention looked nothing like the traffic lights we know of today. The lights we know today more closely resemble a signal designed by William Potts in1920. Morgan did make out pretty well, though. General Electric bought the rights to it, netting Morgan a sweet $40,000. That's equivalent to about $600,000 today. Morgan should be more revered for his Safety Hood invention, which would become the gas mask, literally saving lives in a mine explosion.

I love this, thank you for sharing!
this is still how the light ccle works in Germany! This is just so much safer and more comfortable as well.

Please add a "How traffic lights should be used" video for my country.
You forgot to mention some emergency vehicles (police, fire and ambulance) may also have a remote control to change the light when approaching them.
He did

@@cjsebes thanks didn’t know
Its not weight sensors, its inductive loop sensors…

Ah, a fellow U.S. Citizen.
Why do lights turn red for me with no one else approaching intersection? I don't know why but I shoot them out and go anyway
Starts at 1:38
jzak
very informative
Thank you!
Yellow light before red, in Serbia doesn't mean stop but speed up :)
New Jersey
lmao
It means the same here in the Dallas/Fort Worth area too!
Serbia? Haha
Yes, that's true even in India

This video teaches me very good
Underated kept it up
Very nice video.

Here is something which traffic lights which a lot of people did not know before.

Thats how they bait you and giving you a fat ticket 🎫!
Never know how they do it but they have control system!

The main reason for road rage 😤

I, a human assure you that humans(like me) will not be automated in the 22nd century.

Walk,Bicycle, motorcycle, cars, airplanes when passing intersections Y have to be following the traffic laws.
Respectively I am
You should also mention that Garrett Morgan was the inventor of the traffic light. 🙄
We learning how it works not it’s history

Unless somebody just ask google
What is traffic light?
Interesting
Why traffic light timer 30 seconds not a minute
Thing that we all have seen in real life 😅😅😅
Let me guess you could never pass the are you a robot security portion hmmmm ROBOT!?
Which Algorithm they use ???
TIL there isnt a dude controlling traffic
I hate traffic lights!
No we need traffic lights too much crazy people on the road.
Cool😉😉😉😉
Rip grammar for the title
what? there’s nothing wrong with it
I’m telling something is going on in Ohio
Its NOT really its started in United states by a black man
Traffic lights are very impotent.🚦🚦🚦🚦🚦🚦🚦🚥🚥🚥🚥🚥🚥🚥
