Red ring of death.
I like that there is already an idiot on the top-left road who passed the whole trafficjam on the wrong side of the road (because “I am special”) and is now also stuck there because there was a reason for everybody to not move foreward
Kinda looks like a cop to me
Might be. I don’t remember seeing any police when I was in Norway, but the internet-pictures kindof match.
I still get nightmares from thinking that placing a nice roundabout in Cities Skylines will improve my traffic only to come back later to see a huge traffic jam because the cars are blocking each other.
Honestly I’ve never heard about a roundabout traffic jam before seeing the picture of the Norwegian four-way bus lock a couple of days ago, followed by this example right here.
I think Cities Skylines is either badly programmed or propaganda for Big Intersection.
Yes
Basegame CS’s traffic system is notably bad - if you wanted anything realistic you needed mods to change it. No clue how CS2’s plays, but I can’t imagine it’d be much better.
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.
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’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
Guy that went and directed them said they were stuck for a total of 3 minutes.
It took him 3 minutes to direct them start to finish, but they were stuck for total of 10 minutes. He didn’t start directing them the second they were stuck.
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 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.
What’s the context on this?
Step bus, what are you doing!??
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.
I’m very curious about who screwed up first
In my opinion the stupid bus that entered the round about when already 3 buses where in there.
I mean get that there was space, but man you could have waited 20 seconds and everything would have been fine.
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.
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
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.
This is what my trains in satisfactory do :,)

Why though? If you zoom in you can see that they’re literally filled with people and allow easier/quicker stops as they have many doors. If you actually plan their routes they work quite well.
This can be fixed by the drivers paying extra attention in front of them when entering a roundabout.
When you enter a roundabout you need to be clear from the left, that’s normally all you need to worry about. In this case because the buses are so long, the bus that locks them is in front of them when they enter, and there’s another bus to the right. This should be clearly visible.
Definitely bus drivers’ error. They are the big vehicles, they are the ones who need to pay extra attention to whether or not they will fit anywhere.
When your factorio base logistics collapse and you have to manually unfuck the train system
Solution: goatse roundabout
Jacques Tati did it better
We do a little trollino-ing.
