This is one of the most complex levels
As soon as I saw the image this is exactly what I started doing in my head.
I finished this in 8 moves? Not that hard
Factorio players had this solved forever ago
No they don’t. They still have nightmare of item contamination.
Should have used filters…
Usa a semaphore.
Tbf, they also have the arthropod invasion sorted out.
And now pentapods too
I did, then spaceage broke all my old intersection templates
Yeah, I’m still a bit irked about that. But the new system is good at least.
I’m sorry, but this looked super easy to un fuck. The bottom driver just had to pull forward a bit and to the right, enough for the guy on the right to get through. I don’t think they were “stuck” so much as this was a cool photo with a click baity title.
They were stuck for 10 minutes and needed to be directed from the outside. It’s maybe not that long, but they struggled with figuring it out. Source (in Norwegian, this happened in Oslo): https://www.vg.no/nyheter/i/3pkoP9/busser-fast-paa-alexander-kiellands-plass-i-oslo
there are probably cars there facing the bottom bus, no? it’s the enter lane, not an exit lane
Also, fewer cars will help.
It is, but none of the four bus drivers have all of the information. You will also need two or three cops or at least guys in fluorescent vests to physically block traffic from entering the circle and or bitch-slap selfish asshats as necessary until the Gordian knot of buses is untied, otherwise said selfish asshats will try to barge into the intersection the second the first bus moves and start everything all over again.
I’m very curious about who screwed up first
I think it was a combined, synchronized effort
Apes together stuck.
Bus on left hand side of screen sealed the deal, but it was a concerted effort of fuckery
Each one of them screwed up independently. It takes a concerted effort to reach this situation.
I don’t know what’s going on in this picture, but, whatever it is, being accidental is last on my list of possible explanations
It’s a deadlock situation and can arise without any screw ups. Imagine the buses being 5x as long and all reach the intersection at the same time as an example. All have space to enter the roundabout but they’ll reach the same situation as in the picture.
To fix this people uses signals and can be done by having the buses follow “Only 1 or 2 articulated (double) buses are allowed into the roundabout at a time”. A rule like that might be required if you have a lot of articulated buses. The risk of this happening depends on how many ways you can enter a roundabout no a bus like that, how long the buses are, how frequently they run and how big the roundabout is.
1 of 2. Either the car drivers going on the inside of the busses, hindering them enough space to make the turns, or the bus drivers allowing it to happen.
What’s the context on this?
Buses stuck
o.o"
bus #1 needs to move so bus #2 can move
bus #2 needs to move so bus #3 can move
bus #3 needs to move so bus #4 can move
bus #4 needs to move so bus #1 can movei n f i n i t e l o o p
It we’re forcing a programming analogy, I’d go with deadlock over loop.
Spinlock even
I dread what “answer” this may bring but…why?
To clarify: this is not intentional art. This is an engineering edge case turned real by bad luck.
Normally 3 buses can use around-about without issue, and there’s plenty of 4 bus patterns that could use the intersection without creating a knot, so bus drivers probably aclimate to having another bus or two in the loop, but this just happened to have the bad luck needed to create the knot.
(And OP is calling it an art installation tongue in cheek because it’s not going anywhere for a while)
Thank you for clarifying. People are so silly.
Context is the photo where no one can exit or enter the roundabout.
Step bus, what are you doing!??
This is what my trains in satisfactory do :,)
Red ring of death.
When your factorio base logistics collapse and you have to manually unfuck the train system
It does not look like any bus screwed up to me. It looks scary ya I agree, but I’m sure watching this play out was very mundane and efficient.
Solution: goatse roundabout
Alexander Kiellands Plass will never not be a traffic nightmare.
Jacques Tati did it better
That is what, six years old?

Do not enter the intersection unless the exit is clear.
That’s a roundabout Sir. Different rules apply, because most often the exit is simply not visible from the entrance. You enter the roundabout when it is safe to enter. And in cases when the exit is visible, because the cars are constantly entering and moving around, you’ll never really have a clear exit even with normal traffic.
The same rules apply to a roundabout where I live, if the exit isn’t clear, you don’t enter.
People do it all the time and block the roundabout, but you’re not supposed to.
Are you sure you’re not talking about a traffic circle?
Roundabouts have specific rules, not every circular intersection is a roundabout
No they don’t, because that’s not how roundabouts work. I won’t believe you until you show me some proof of said rules.
In the meantime, you can go read about how roundabouts work and why it wouldn’t work if people waited for the exit to become clear.
You do understand that a roundabout is an intersection, right?
And I keep telling you that different rules apply to roundabouts. But you clearly don’t understand that.
Just show me the rules where it says you must wait for the exit to be clear at a ROUNDABOUT. Please, I’ll wait.
