Shockwave traffic jams recreated for first time

Why doesnt anyone just cut across the circle and win the race?

So nobody was doing a constant speed 30mph then.

the reason? some people are just bad at regulating speed.

40 second video gets 50 second ad

Alright, which human forgot to leave their scent leaving them in a death spiral

Circles dont work because idiots give courtesy rather than follow the rules

Can someone please explain this to the guy I work with. He gets soooo mad at this traffic phenomena thinking it is just dumb drivers driving like idiots.

It's a case of f*ckin idiots who cannot obey the simple rule of 30kph. This would have been the only time they actually focused fully on the situation in hand ,and they fucked it up. Beware on the roads people, stay safe 🙏

Cruise control solves this problem.

In other words: people are stupid

What they need research to proof this?

Same goes for traffic lights😠

I always called it the Slinky effect

So sometimes huge traffic jam can be caused by just one idiot driver😂😂😂.

All started due to a stupid driver

The correct response to traffic shock waves is to calculate an average overall speed and stick to that. Let those gaps in front of you grow and condense regardless of the frustration of those behind you. Just like that you've stopped propagation backwards.

Il 90% è dovuto a questo; poi ci sono i cerebrolesi che ralllentano per guardare l'incidente avvenuto nell'altro senso di marcia dell'autostrada 🤬

Coordinated self-driving cars are the way. There's no reason an entire lane can't maintain the intercar spacing as the whole column accelerates and decelerates together except that humans can't do the coordination. The human reaction time accumulates as the singnal is passed via brake lights from driver to driver. Computers could propagate the signal in a millisecond or multicast.

Looks like Paris: breaking or stopping for no reason 😀

This changes everything.

I think i had a nightmare like this.

One time I looked at a traffic analysis textbook in a college bookstore. It was full of calculus, differential equations, and other higher math I didn't know anything about. I had no idea it was such a complicated topic.

I named this the slinky effect.

Slinky traffic.

Brilliant, Forty seconds to demonstrate what must have taken a lot of organising. Well done! Now I have even more respect for the Japanese.

This is also known as "road memory". It is why you encounter the same congestion on a patch of highway for no apparent reason. It is the result of the delayed slowing/stopping of vehicles that were there previously.

Why can't most of you drive forward quicker at lights? You just sit there looking at the green light! I bet you get to the end of the checkout and look surprised when the cashier asks you for money!

Someone was doing 31 kmh

It’s like when you’re in basic training and at the end of the marching column. You pay for every inch anyone in front of you falls behind.

I believe this happens due to the average driver IQ being low. It's just a theory, but I imagine putting the right people in this experiment would maintain the velocity wiht low variation whereas putting the "right" people would cause a crash

It's the woman in the white car that started all this mayhem ......

Basically, this proves that certain drivers need to get their ass into gear and stop creating more traffic by dawdling behind the wheel

This makes me wonder if NOT having a speed limit is actually a GOOD thing... I wonder if there's a correlation in car accidents, and traffic jams and speed limits. Where are there LESS accidents and/or traffic jams in the world? And do they have speed limits? 🤔

Also, reduced speed limits, LTNs, cycle lanes taking road lanes, bus stops, traffic light over use, road slowing measures, congestion charges, cyclists, etc.

Because no one can keep a constant speed to save their lives

Conclusion: people are idiots

Leaving space for safety invites cut-ins, so we get closer to the car before us, in order to avoid that. So, we intentionally tailgate the first car, so that we won't UNintentionally tailgate the cut-in. It's all just different kinds of tailgating.

If you cannot adjust your speed by letting off your gas without using your brakes, then YOU are creating traffic jams.
Drive in the driving lane, (pass only) in the passing lanes and return to the driving lane or YOU are creating trafic jams.
Do not ever impede faster traffic and signal for what you ARE going to do, NOT for what you already started doing.

it's posted 16 years ago, but video itself is from early 90s

Eventually, someone tailgates too close and someone stops suddenly, throwing the tailgater into the rear of another car. That causes an accident.

What did you expect with Oriental drivers.

Ok, we have known about this for at least 16 years so... any ideas?

Well there’s the problem right there.. it was a Japanese research lmao

No doupt Women drivers caused that 😂😂😂😂😂

Because of a couple of idiots

also called "the Accordion effect"

It just takes one weak minded cowardly person to fck it all up. Add texting and putting on makeup and there is no hope.

I wrote a piece of software to simulate this way back in the 1980s on my commodore pet - it's a real thing.

I call them gap-sters, Another eg. When a red light turns green, the first car goes then the next car (a gap-ster) will hesitate to drive (maybe looking at their phone, day dreaming etc) then the next car drives off hurriedly then the next gap-ster goes with a delay. Then the light turns red. So instead of 8 cars going through the green light, only 3-4 get through.

Old ass news
