Testing VIRAL highway layouts in Cities Skylines 2!

I'm impressed that this viral idea managed to integrate the worst aspect of cloverleafs (overlapping lane crossing in both directions) with the worst aspect of roundabouts (the lack of express lanes). It's efficient design in terms of maximizing disadvantages.

When we see our city has traffic issues we see a problem. When Matt sees the city has traffic issues he sees content

The turbo roundabout should not be double lanes. Should be singular lanes. Also the lanes on the inside are not fully connected. They stop 3/4th of the way to avoid giving way a million times. In the Netherlands you got plenty if these roundabouts and they work perfectly fine.

As a dutchy (and someone who uses a turbo roundabout every day) that turbo roundabout does not work as intened at all. That's mostly because of CS2, in reality they work great! As long a everyone follows the signs and arrows it's great.

13:15 you know how you change a 1 way road by using the replace tool and drag in the opposite direction? That's also how you change the direction for an asymmetrical road :D Also 17:15 you remove them the same way you remove stop signs and stuff: right click

I know the name of the architect prison is due to the poo moat…..but Architraz has such a better ring to it😂😂

Turbo roundabouts are fairly common in Spain, but they are a lot simpler than what you built, they're nice because they eliminate the problem of the car on the inside wanting to turn out while the one on the outside wants to stay in. Most of them have traffic lights, though to be fair, most urban roundabouts in spain do, we even have some horrid roundabouts with traffic lights inside the roundabout for the cars inside it to give way to cars coming in. In southern Spain (mainly Málaga) I've also seen roundabouts where the main road goes straight through the middle sorta like this Ø and imo they are a mess of traffic lights and worse than a regular roundabout in every way, but I'd love to hear your thoughts on them

So, I live in Metro Detroit, and all of our major intersections look like that. The difference is that we still have stoplights, so people can just go straight. You can’t turn left at the light, so if you want to turn left you have to use turnarounds by making a right, or by going straight through the intersection and using a turnaround (if it’s a large divided road of the same design). We call those “Michigan Lefts” because we love turning right on red, and from a turnaround it’s also legal to complete a turn if the traffic is clear. That said, there are interesting situations where having intersections built like that are helpful. During a power outage, cops will often park in the middle of the intersection to block anyone from driving straight through, which turns it into exactly the thing you saw in that video and recreated. My area has an annual street cruise, where they block off a lane and several turnarounds for classic cars only, in addition to blocking the traffic from traveling straight through on the smaller crossroads. It’s annoying because you have to drive over a mile out of your way because of the event traffic, but it allows for a consistent (albeit slow) traffic flow, which is far safer than trying to drive through an intersection that size without the help of the lights to cut the flow. Sometimes there are lights that hold traffic using a turnaround, because there’s just too much traffic for it to be possible to continue without the assistance of the light. At less busy times of the day, it turns into a blinking red, and often at very busy intersections they will post a sign that says “No turn on red” at the light where the roads meet, and sometimes at the light they put at the first turnaround. I’ve seen smaller cities in the state (several hours north) where they don’t have much real traffic, and they do goofy shit where they allow people to turn in addition to making a proper “Michigan Left.” Those intersections have accidents, because they’re subverting the expectations of how those divided roads and their massive intersections function. We basically don’t have any mass transit in any part of the state, because back in the day, the automakers made sure to shoot down any attempts at that, and they influenced Detroit’s politicians to get rid of the fairly shitty, electric street cars, that were ridiculously unsafe for pedestrians, because they were in the middle of the road. So people would run from the curb out into the middle of the street while they were stopped, and it wasn’t like they were necessarily timed with the lights, so these things would block up the turn lane, in the dead middle of the road, and they would hop on or off whenever it slowed down, while there were cars zipping around in all directions. It’s amazing that more kids and older idiots weren’t killed. I think the reason they got rid of them was because the overhead cables looked like shit and prevented taller vehicles from traveling through the areas where the streetcars were, and I’m sure it chapped someone’s ass that deliveries had to go around or be offloaded onto smaller vehicles for the last leg. Honestly, I think you’d get a kick out of looking at some of the ways we build roads here in Detroit, because we’ve been doing it pretty much longer than anyone and solved a lot of the congestion problems ages ago. The divided roads with turnarounds are great, because even if traffic is so bad that you literally can’t get across all the lanes in order to make your turn, you can keep left and go through to hit the turnaround just past the intersection, or if you made the right, but can’t get over to the left because of a backup caused by construction or an accident, or something, then you can keep going straight and working your way over to the left lane, and just use one of the other turnarounds a little further from the intersection. It sucks going just a little bit further out of your way, but it sure beats sitting still with a turn signal on, while holding up traffic in order to get over. Of course, there are morons too stupid or too rude to do that sometimes and they will try to force their way into the line of cars—but those people make your architects look like saints or engineers by comparison. Literally the worst of the worst that even pedophiles can fairly claim to have moral superiority over. Sadly, these oxygen thieving dregs aren’t as easy to spot walking amongst us, otherwise we would’ve sorted out their ilk a long time ago with some sort of human rights violation or war crimes.

Imagination is the highest kite one can fly.

Only a few minutes in but this junction doesn't seem to be intended for equal amounts of traffic from each side. It is more a onto a highway and off a highway situation. Not crossing streets with equal amounts of traffic. Especially the north south route is really blocked by this junction

I remember the viral image in question, the animation for it never showed anyone merging off of the central "Not-roundabout" and the same cars stayed in that lane forever, constantly looping.

The turbo-roundabout might work better with less lanes, and also by connecting it up correctly. They were all over Aruba and about the same size as ordinary roundabouts on similarly sized roads in the UK, with only one or two incidents of tourists running over the big kerbs in between the lanes on the roundabouts that I saw.

The U-Turns make sense if this is a separated road with many access points. When you enter the road you can only go one way (left in your case) and if your destination is to the right, you'll have to go to the next interchange or roundabout to turn around. There's a system called a "Michigan Left" that is kinda similar to this but with signal control. Growing up with them all around, the idea of turning right to make a left is not so crazy to me Also, to get the asymmetric road to go the way you want, click hold and drag in the direction of traffic you want to have the extra lanes

We have those turbo-roundabouts all over the place here in The Netherlands. Very efficient. However, I have seen foreigners get so confused they stop and start reversing. I know, reversing on a roundabout.

That Interchange you were looking at appears to be along the lines of a Median U turn lane aka Michigan left. Pull up your favorite world map software and look around the Detroit area, particularly Woodward ave, Telegraph road, 8 mile, and Big Beaver Road (a few miles north in Troy). Have a fun moment if Following I75 north to Exit 69 Big Beaver Road (Diverging Diamond interchange)

I find you, the engineer, not understanding the purpose of having a u-turn to account for the human element of mistakes, hilarious

I'd love to see how a Diverging Diamond interchange would work in CS2. Not sure how popular they are in Europe, but I've had a few pop up around me in the US. Basically, it's an interstate interchange that is designed so that you never have to cross over traffic to get on or off the interstate. I actually quite like them. Cheers Matt and Paddy.

It’s amazing how much my highway design knowledge has increased by watching these videos. Where at first I would have been totally lost by Matt’s explanations, now I can follow along. (Though I definitely still don’t know enough to contradict what Matt says).

Honestly coming from the Netherlands. Those turbo roundabouts are amazing. They look different than yours but they work great.
