Cities Skylines

Motorists are fucking stupid and anything less than lights is too much for the average driver.
Something that might be the best on paper quickly devolves into crashes.

Ban cars. Traffic becomes far more manageable when everybody rides bikes or public transport.

>>1100880
Absolutely not this.

cloverleafs are being phased out all over the US. its just not a good system because the mergeon/mergeoff lane is the same lane and its so short causing backups and accidents

>>1100942
>because the mergeon/mergeoff lane is the same lane and its so short causing backups and accidents
It worked fine for decades.
Personally, I think it's a mix of people becoming poorer drivers on average (I blame automatic transmissions), and the rad construction industry shilling boards like this with posts like yours in an effort to manufacture support for unnecessary upgrades.

>>1100945
> worked fine
No. It breaks down under traffic volume.
> unnecessary upgrade
Tell me that when your idea of a full cloverleaf has collector-districtor lanes.

roundabouts with speed cushions every 100 meters.

fuck cagers

>>1100884
Around here they went roundabout crazy and started putting them everywhere. Now they are installing traffic lights at the roundabouts because it's too much for the average cagers brain

>>1100880
You want an IRL answer or a cities skylines answer? In the new update you can remove lights from intersections, its on the top left drop down menu. IRL use a stack interchange, just brute force the shit and prevent weaving lanes

>>1100884
>Motorists are fucking stupid
So like real life then?

>>1100975
Can they not follow lane markings on a spiral/turbo roundabout?

>>1101038
No. I live in a state that is traffic circle crazy, so everyone should be used to them, but I narrowly escape little crashes every single day because no one wants to yeild.

>>1100945
Weaving lanes are undeniably bad and we know they're bad. Upgrades are warranted as cloverleaves are just not good anymore. Construction shill seems like a non issue when there are alternatives that cost hardly anything and yet we know for a fact they are better. No one is suggesting to replace every on-ramp with grade separated billion dollar high speed ramps or something ridiculous.

It might have worked fine when the average speeds and volumes were much lower than today but trying to merge from a crazy short weave lane is not fun, regardless of your driving capabilities. Higher capacity, safety, and throughput are not unnecessary.

Another serous problems. Cloverleaf FIRST ADS traffic to road, and only then it takes out traffic of cars merging out to leaf for left turn. Obvious problem if you start add traffic to road working near maximum capacity you are creating conditions for traffic jam. Even worse, cars need to merge out through this jams. Very bad.

Turbine interchange on the other hand first takes out traffic of cars which want right or left turn and only after adds traffic into road, onto right now empty lane.

>>1101038
nope they absolutely can't

it's been a couple years since they started adding roundabouts to new subdivisions and roads and people still don't understand them

Almost daily people will just enter in front of you without slowing or yielding and cut you off, if they are multiple lanes they just drift wherever they want inside the roundabout like common road rules don't apply in them. It's madness.

I used to take one with 3 lanes on my route to work and it put me on edge every time other cars were near

I like parclos because it's all at grade so they're a cheap way to do an interchange except they usually involve lights, and the cirle ramps are usually pretty tight curves so you cant accelerate until you're on the freeway

>>1100942
Cloverleafs are getting phased out for parclos because the parclo is cheaper bud

>>1100886

I have tried these in a few areas in C:S and they work well with medium traffic but not heavy traffic.

With heavy traffic (like industry trucks) the only thing that works is one way bypasses that avoid intersections.

>>1101335
Roundabout interchanges are perfectly great for normal roads (ie upgrade the major road or both intersecting roads to overpass/underpass for grade-separated through traffic).
There are special designs to be used on roundabouts for junctions favoring particular sets of directions, generally they are of turbo roundabout origin.

>>1101375
I'm not autistic.
What's the difference between a roundabout in Bongland and a traffic circle in the States? What's the difference further ina TURBOroundabout?

>>1101297

I have noticed most American on and off ramps introduce traffic before removing traffic. Why?

Why do so many plebs make monorails?

>>1101450

See that sharp circle turn?
>>1101324

>>1101268
At the points where the lanes of the arterial road underneath the highway cross over and interesct--why have them intersect with stop lights halting traffic? Is it not possible to have elevated one lane over the other to keep traffic flowing, unimpeded by the opposing lane?

>>1101466
But I seem to run into problems every day with this interchange around me, where I need to get over, or else I'd be getting off the road I need to get on, and no one lets me over because they're trying to get off, so what happens is that both roads come to a halt.

>why have them intersect with stop lights halting traffic?
Cost. At grade intersections are much cheaper. If you want to check out a freeway with a huge variety of interchanges look at highway 400 in Ontario on Google maps. Since most of the highway north of thw city of Barrie just cuts through forest, the interchanges are designed only to the standard that traffic in the rural areas required. Like look at this;

On the left theres a parclo interchange where you exit the highway to traffic lights, but you enter from an arterial road lane.

On the right it's a rural interchange where you exit the highway to a stop sign, and you enter kind of on a right in right out interchange.

It's just done for traffic need and cost

>>1101469
This happened to me the other day and I ended up on a North South highway when i was heading East. For connecting freeway to freeway they just need to make longer ramps to give people more space to move over i guess. But they do allow for maintaining speeds of 100kmh whereas other forms of interchange require you to reduce speed

heres a dumb example, yes this isnt of a cloverleaf but this situation happened to me once. I was merging on while a semi was trying to merge off. I was already going 30mph or so mergeing on and so was he, the only solution was to either overtake him (dangerous) or step on the brakes

>>1101484
Yeah that's super fucking dangerous. The exit should be before the entrance ramp like here
>>1101324

Not from England, only sort of a Commonwealth place.
1. There are reasons suggesting they are the same thing but for technical purposes you can give some difference. My take: Traffic circles are plain circles, old roundabouts in general. Modern roundabout introduces lane markings to let drivers choose their way easily and guide traffic better. making them spiral roundabouts.
2. Turbo roundabouts are a step up with varying numbers of lanes in the circle, providing for converging and diverging directions of flow like ramps. It is more stringent on lane use than spiral roundabouts. You can see it as literally a bunch of parallel lanes slapped together into a circle and intersecting. That's what makes the central island of turbo roundabout anything but a circle, because of the bulges from additional or reduced lanes merging.
I'd love for input on spiral vs turbo roundabout as it is a bit more in depth. I can't gather a reliable definition casually.
FYI a rotary is just one big roundabout.

>>1101458
They didn't install MOM and thought it is a surface version of the already broken metro.

>>1101450
Weaving design is cheap and generally 1 to 2 levels?
>>1101471
Thus make a collector-distributor or full local-express lanes for weaving provisions. >>1101484

>>1101466
Doesn't seem convincing enough. Non-directional ramps are good at space-saving.

>>1101468
Look you are looking for a better 2-level service interchange. DDI it is. If you want something bigger elevate the minor road to be a DCMI.

>>1101297
This looks very expensive

Fuck I miss this game, laptop absolutely shat itself and I've been spending too much money to replace it with anything decent.

>>1101598
Still cheaper than stack interchange.
One caveat at map interpretation. 2-level system interchange that looks complex like the whirlpool/turbine here is less vertical space-consuming.

>>1101590
I just dont understand how intersecting lanes makes it better. Wouldnt the idiot proof thing just be one circle and that dont have to merge during?

>>1101381
A traffic circle gives priority to vehicles entering the intersection.
A roundabout gives priority to those in the intersection.

>>1101268
wtf? two roundabouts would have worked better.

>>1101693
Umm you still have to deal with merging traffic in the circle?
Lane-marked roundabouts codifies lane changing and merging behaviors, reducing conflicts, increasing safety and capacity.
There's a point about the loss of u-turn v traditional unmarked roundabouts. That's justified by accommodating more traffic volume. I haven't seen such designs but this sacrifice may be easily compensated with an added U-turn in the median before the roundabout, while also allowing for a pedestrian island.

>>1101381
>>1101706
Yes this.

>>1101708
You retrofit existing diamond interchanges. DDI are better for through traffic on the minor road than dumbbell interchanges. By definition a roundabout ideally has no major flow direction, easing the spread of traffic over different entry and exit points. Further more weaving free-flow designs breaks down under traffic volume. At this point a signalized intersection performs better to control traffic and give priority to certain sets of directions.
You don't always have the money or space to upgrade interchanges.

>>1101716

>>1101721
This, dirty diamond is best interchange

>>1101721
You only have go merge on once and just exit when you get to the spot you need, though?

>>1101324
Holy hell this is retarded.
>requires ample space
>still has tight as fuck curves
>AND requires traffic lights
Tell me the advantage of a parco over a standard diamond interchange with dedicated right turn lanes.

>>1101922
Takes up less space, all at grade, the bridge can be smaller

>>1100880
The best interchange is eugenics, proper education, and a reformation of transportation mediums. We must break the addiction to combustion engines. Anything less is prolonging retardation of humanity.

>>1101922
No weaving.

>>1101922
Also no weaving

>>1101922
What's the problem with tight curves? It's not like you're suddenly ejected into the main traffic flow, you have like a mile of your own lane to merge from.

>>1101484
That's why we called those "collide and destroy" lanes back in the Usenet days.

>>1102022
I'd say they makeup at least half the roads here

The most important bit in the "best interchange to manage traffic" would be: No human drivers.

Fortunately we appear to approach that point at high speed.

Is the two-lane roundabout really necessary?
From real-world experience those only create confusion, and the only [spoiler][/spoiler]case where a car enters it is to turn left, (or turn around but that's really rare).
So when you enter the outer lane with a car moving in the inner one, it's pretty much guaranteed he's gonna want to leave at the next exit while you want to stay on the roundabout.

>>1102430
>>1102661
>>1102671
You've got the road markings completely wrong. Are those things at the end of the bridge meant to be zebra crossings? If so, replace them with pedestrian bridges/underpasses. If they're not, just delete them (though you should probably add pedestrian facilities anyway).

Through traffic on the road going over the roundabout should have right of way at both ends, and there should NOT be a gap in the median. Left turning traffic should use the roundabout and get off on the other side.

If traffic volume is high, consider a third lane for traffic from the roundabout to join the road beyond it. It can end in a merge 50 to 250 metres later.

And you should NOT have a merge between the roundabout and the junction. Traffic using the corner lanes should give way to traffic coming off the roundabout instead.

Are there any real world examples of three level roundabout interchanges being distorted to fit onto two levels?

Two types of roads in C:SL.
The game kind of treat surface roads, bridges, tunnels as different types of roads so when they to transition to each other ordinary roads will create crossings.

>>1102903 >>1102992
So is there any reason why the road on the bridge cant be a highway?

It would be IRL - an ordinary road would just go to the roundabout instead of over it.

>>1103067
1. I imagine it continues as the same 6-lane two-way avenue. There's no compact, narrow highway asset in Vanilla.
2. That's the point of it. A roundabout service interchange with grade separated minor road increases capacity and doesn't disrupt the through traffic.

>>1103071
1. What end-of-highway options does it have?

2. Do you know of any grade separated minor roads on roundabout interchanges in the real world?

In Britain (where AIUI there are more roundabout interchanges than anywhere else) if there's a second grade separated road it's always a highway (usually a freeway without official motorway designation). If all they want to do is increase capacity, they just add lanes (and possibly make the Turbo roundabouts that >>1101375 mentioned).

1. Unsure about OP's intention so ask him.

2. Agree these are rarer but they should exist. Can only think of this one from my country: Pok Oi interchange, Yuen Long. Castle Peak Road is at most a divided rural limited-access road.
Conveniently it was further upgraded last year so you can enjoy nice drawings.

If you count gyratories we have Cheung Wing Road Gyratory, Kwun Chung but there's more of a system interchange with two intersecting avenues, although one of them (Castle Peak Road again) continues controlled-access southeast and has a short stretch of limited-access west.
There may be more candidate interchange for upgrading to such, one particularly busy that unfortunately has an elevated metro station across the roundabout island.
