>>1063983
This is some kind of niche, expensive interchange. It does not have much through traffic capacity at all. If it ever has more traffic than the 1 lane of through traffic can handle, it would cost a fortune to upgrade. I don't think any sane government would pay for this.

>HUGE collision zone in the middle
literally how

>>1064321
There are a couple tricks to doing it right, like striping the lanes properly so that cars are not guided into each other, and having the proper geometry for left-turning traffic at the intersection. It's a little odd, admittedly, going by oncoming traffic on the left, but local traffic will get used to it.

The main perks are that they save space and store a lot of traffic, so they scale pretty well. Cloverleafs cannot scale.

The downsides have been mentioned, plus they kind of suck for >pedestrians.

>>1063746
So traffic can't flow east and west at the same time?
Jesus, what a retarded design.

>>1064322
They suck for pedestrians, cyclists, anyone not from the area, and include contradictory lane markings where you have to guess which one is the one for you. If you guess wrong, you get into an off-set head-on collision.
It also seems to include traffic lights on a 6-lane street, so you'll always have a traffic jam no matter how low traffic is at the time.

Can someone explain to me why pic related doesn't replace all cloverleaves?
It seems to be much more compact and you don't have to merge incoming traffic before outgoing traffic leaves.

>>1064406
"hello yes, this is government, fuck you resident"

>>1064411
It requires a more complex system of over/under passes in the center, making it more expensive to build & maintain.

>>1064329
You should check out the cloverleafs in Maryland that just back up onto the freeway. Sometimes a flyover or two is needed. I'm against blatant overdesign of roadways.

>and include contradictory lane markings where you have to guess which one is the one for you
You make it sound impossible. It's pretty clear which lane stripes are for you.

>It also seems to include traffic lights on a 6-lane street, so you'll always have a traffic jam no matter how low traffic is at the time.

If it's a surface street, it's going to have traffic lights no matter what. If it were a standard diamond interchange it would have two traffic lights.

That's what you get from the above, not so in height. For this it is expensive and complicated, ugly if you are living on its fringes.

Plenty of other designs, plus this may not be necessary depending on traffic volume.

The two worst traffic situations in my county are two places where US-1 can't send traffic north and south at the same time.
Traffic backs up far worse at these two places than anywhere else here.
It cuts the throughput roughly in half.

What's the point of those lights?

>>1064701
They don't exist in all the DDIs. They're optional, particularly for when you would otherwise have a lot of traffic trying to merge.

>>1064701
They are synced up with the mainline switch lights to give conflictless merges to the offramp.

Also, half of them provide a protected pedestrian crossing.

>>1064321

>>1064180

>>1063704
The cloverleaf with flat crossing is an incredibly stupid design. The whole point of a cloverleaf is to avoid the need for traffic lights. If you're going to have traffic lights, it makes sense for the diverging lane to go before the merging lane.

A full cloverleaf like >>1064041 has the advantage of being cheap to build (excluding land cost) because there's only two levels and one bridge. It's the lowest capacity free flowing design in use, though the capacity can be increased a bit by separating the main roads from the merging/diverging traffic going through the interchange (so all diverging traffic leaves at the start, and all merging traffic joins at the end).

A whirlpool junction is better for high capacity situations - more bridges, but still only two levels, yet a similar capacity to the expensive 4 level stack (of which >>1064411 is an example)

Continued from >>1066080

AFAIK nobody's built anything quite like >>1063983 yet, but some of the criticism of it is unfair.

Contrary to what >>1064387 says, there's no unnecessary lane changes. And despite the claim of >>1064320 a higher capacity version could easily be made by adding another through lane each direction on the minor road - or make provision for it (with slightly bigger bridges it would be an easy upgrade). The only disadvantage I can see is that there would be merging in the fast lane. That would limit its suitability to some situations, but for medium capacity situations it looks like a practical alternative to a roundabout interchange.

With recent improvements in mods, we've essentially hit or surpassed the levels of detail we had in heavily modded SC4. The Move-It mod especially is really critical. One of the problems before of CS compared to SC4 was the quite unrealistic highway junctions. Now you can wiggle the nodes around and make much more seamless on-ramps and overpasses, it's led to tons of amazing creations.
