Max200012 : brb, gonna replace my 4-lane roads with Stack Interchanges

Caleb Adams : This is not something you just look up. This is the kind of video you find at 3 A.M. when you should be sleeping.

dilliot2k : and atlanta traffic will still crush it all....

The TNTBlower77 : *cars pass through other cars*

Nataly RAW : 1v1 me on traffic simulator u scrub

M M : This whole video is like that one meme with the mind becoming more enlighten as the idea progresses.

Jan D : Traffic Flow in a turbo roundabout would be 0, because no one would be able to figure out which way he's supposed to take.

mercury : 5:15 hitler is still alive and he’s designing interchanges.

Giancarlo RC : Idk why I just watched this, but it was in my recommended and worth every second

Resz7 : 2:30 entirely too much faith in the driving ability of most humans.

The dark lord : With California drivers? Traffic flow: 3

Peter Liljebladh : Now let's compare how many square meters of asphalt that relates to per car per minute to evaluate the cost effectivness of the intersection.

Maury Hatcher IV : The Diverging Diamond Interchange (DDI) may only place 7th in flow with a 644 score, but I think it's the best in efficiency for its size. You don't always have room to make a full stack interchange, turbine or full cloverleaf, and if you need to use nearly the same size as a typical diamond interchange you already have (score: 437) the DDI seems like the clear, obvious choice; everything higher in flow than the DDI requires far more real estate to accomplish.

De Wolfie : The reason why the traffic work very poorly in Cities Skylines is that the car have pretty much no logic in how they pick their lanes or behave generally. it doesn't matter how many lanes you given into each connecting road. They will all pick the same still. I would say this is because they don't really try to simulate driver behaviour, but more "which is the most optimal way from where I spawn?".

TheFrostyIcecreamSlush : Where are Pinavias in the real world? I've never seen one before o.o

skyscrapersim Dale : 5:15 Bro thats a swastika not a windmill

TheAprilWitness : That was surprisingly satisfying to watch. Then again, I live in greater Boston, so, that's prob why I'm drooling over these traffic solutions.

Frostyfre - Ezyfreeze : I could make expanding brain meme out of this: Junction without traffic light With traffic light Roundabout Diamond Diverging diamond Cloverleaf Turbine Pinavia Make cars out of 4th dimension properties so they can pass tru each other.

Stormy : That Pinavia was super satisfying. So was the Turbine

Killjointica : Just last year was the first time I ever encountered a diverging diamond interchange. I didn't know what it was when I first drove over it, but as soon as I got home later that day I looked it up and was amazed by the simple design. I then went into one of my cities that had some serious traffic issues and did a bunch of redesigning on the basic diamond interchanges I had which were backed up almost into gridlock. That by itself helped my cities arteries flow so much more smoothly. Thanks real world engineers! However, after many many more hours I found the diverging diamond is far more efficient for commercial and residential traffic. I tried applying them to my industrial areas and the traffic was still far to heavy to accommodate the sheer bombardment of imports/exports moving around the city. What I ended up doing was creating something closer to the custom cloverleaf we see at 5:05 with an extra underground route leading off the highway for the mass of deliveries moving in and out of my harbor-railway hub. That almost perfectly solved that issue. Took awhile to really measure everything out, but the numbers are about what are shown there at 5:05, give or take. Cities Skylines really upped my appreciation for civil-highway engineering and the massive amount of variables that go into predicting traffic flow.

Uni Amni : Not realistic. Where is the Road Rage ??

Syrov : I don't care that it's not optimal, i'm building that beautiful turbine intersection from now on

WupperVideo : You will find the custom cloverleaf on most German Autobahn.

P 3 : I wish there was a sim city type game with just traffic challenges.

STR4PP3D _IN : 2:12 lol 360

Warbird 1243 : is it possible to get hard from a roundabout? cause i think that Pinavia just did it

manek santos : Do not forget that is build in *Cities Skylines* (The best city game ever).

PerfumedManatee : Allowing the vehicles to pass through each other seems to be the real win here.

SlevinCCX : A lot of these don't work in the US, Most people don't know you're supposed to enter the closest lane when making a right or left turn, they just enter whatever lane they want.

Xufeng 02 : Name of the songs pleaseeeee

Daniel Nunya Bidnezz : *Stack Interchange comes up* Hey look... its that thing Atlanta tried to build and bastardized. :-P

IWTD : why is this satisfying to watch?

Infrastructurist : The spacy music matches the visuals perfectly. Nice job!

Hari Seldon : Most of these designs look very confusing, but once all cars are autonomous this will be awesome

Fraxlevein : 0:15 Car drives through another car

Stormy : You need a map for that turbo roundabout

Josh L : Hmmm ... no wonder I see so many stack interchanges in China :O

Just Jum : Which one is the fastest with no mods? Is it 4:55?

Gabriel Sasala : 2:31 I wonder how many accidents were caused by this

AxCYeR : a lot of beauty about these shapes

Oh No its Dexter : Who else saw Austin McConnell’s video about the diverging diamond interchange and looked for it here?

sarysa : Am I the only one who thinks the Contraflow left at 5:40 has turns that are far too tight? I remember years ago when accidents at the Bay Bridge (which wasn't as tight) triggered that section of the bridge being rebuilt...I can't help but think the Contraflow left is one of those designs that seem better on paper.

Tom Vincent Hermoso : Music?

Jawad323Cool Jawad323cool : How come the cars can go through each other

HappyKoalaBear : What is this game?

Timotius Marbun : 3:07 Holy shit that car is in a hurry

xWhispy Plays : 5:12 hidden swatsika...

Kernels : Even how good your highway at traffic flow may be.. The problem is still at the cities and compact cities themselves. (The best highway design is basically getting rid of intersections.) So, if we could get rid of intersections inside the city, in theory, we can optimize the traffic. But the main problem is humans. We should just get rid of humans.

Gewel ✔ : 0:45 they clip through eachother
