Diverging Diamond Interchange Tutorial (DDI) - Cities Skylines

[@AMacProOwner]

This overpass is so realistic it needs to fill out paperwork before being built! :D

[@wyzemann]

This entire upload was full of ENLIGHTENMENT. I've downloaded countless variants of DDIs from the workshop & hated almost all of them. Until now, I had no idea how to properly set up the entrance/exit points to prevent ongoing bottleneck and gridlock traffic. That pillar node maybe your best advice on this one. Now, I'll probably never angrily bulldoze another DDI again, thanks to your expert and detailed video🙏🏾🌟.

[@YUMBL]

Such kind words, thank you! Yes, the center pillar/node is absolutely crucial for the overall functionality. I ALMOST forgot to mention it. The traffic still weaves there, but you can set up an extra light on the highway off ramps to solve it. Have fun, and thanks for watching!

[@qunewsguy]

As much as I love your intersections your detailing work is always stunning! Nice job!

[@YUMBL]

Thank you so much! :)

[@Zreezy]

As always, a PRO cities video by a PRO cities builder. Killing it, Yumbl! Starting in the middle is a great tip, btw. For over passes, I usually stick with 12units. I used to do 10, but 12 feels like it breathes a tad more. I can't wait to try this interchange out myself in my city! Keep up the good work man, this tutorial was great. You are continuously solidifying your spot in the (imaginary) list of top Cities builders! ;) hahah

[@Zreezy]

As a follow up, I'd love to see a video of "how to fix various traffic solutions (with or without mods)", if you are ever interested in doing something like that. I often have the problem where all the cars only use 1 lane on the highway, and don't use all 3 lanes like they should. I have mods available, but not quite sure what to do to fix that. I am guessing there is something in Traffic President that I could do that I am just missing, but idk. Just an idea for you!

Thank you very much! And yes, i’d love to do a traffic manager/management video. There so much to talk about!

Yo brother man, you're the Michael Angelo of City Skylines, there's no one that does it any better than what you do. I can't hardly believe how much skill and talent that you possess when it comes to road design and management. You're by far the best that I've ever had the pleasure to watch here on KZbin. You're knowledge and insight into creating fully functional roads and highways is seriously impressive and I learned more with each and every video that you share with us. So I just wanted to let you know how much I appreciate you and your talent in doing these video's. So please keep up the amazing work and I promise to keep sharing your video's with as many people as I possibly can. Take care and be blessed beyond measure brother man. 🤟🤓👍

You’re too kind! Thank you :)

[@frankstrobel8502]

I recently discovered your channel and love it! Thank you so much for these super well-made videos. One of the main problems I have in my own cities is inner-city interchanges and highway exits. Most of the assets available are huge and require a lot of space. Also, they are not zone-able on the edges. What would be super cool is to have a very tight inner-city highway exchange and one could zone to very closely. Just a suggestion.

[@YUMBL]

Thank you very much! Thats exactly what the single point urban interchange is. Small footprint. From a realism standpoint I think the CS interchanges are tiny compared to the scale of their real world counterparts. You can make it even smaller, but I think theres plenty of map space for a gigantic city AND some nice big interchanges :)

[@nilsdock]

i love the cut and fill, it makes it bend in with the landscape and both roads get a gentle curve, simply beautiful. what you could do is to make the central point of the bridges the highest point, the bridges would then be slightly curved, the advantage to this is that you would move less dirt in total because the highest point of the earthwork can be lower, but the bridge would span the same length and cost the same (or less since it is an arc and therefore stronger) not sure if this is done for real though

[@YUMBL]

Great idea! It would be great for drainage I’m sure as the water would run down without pooling irl. Unfortunately in skylines nodes look a bit weird when you peak them like that in my experience. But yes, cut and fill is the way to go. Thanks for watching!

[@nilsdock]

@@YUMBL if you increase the height by say one meter in the middle of the span, you can use node controller and use the make sloped button for the adjacent nodes it should look alright.

[@mayw6571]

I used to live near Dorset Rd and Interstate 270 in St. Louis, which is a DDI that runs through an underpass. I have heard it's the first DDI west of the Mississippi too! Thanks for the welcome tutorial!

[@granderondeproductions3286]

I like your videos bro. It reminds me of all the road trips I've been on in this great country. There's a few of these in Missouri. Now, they're really taking off throughout the midwest. EDIT: So, as far as pedestrians go, there's one particular interchange for us-65 for I think the main exit to Branson, and the sidewalk goes in-between the roads with the overpass. I know, because I have walked it! its not confusing so long as you use the crossing lights.

[@YUMBL]

[@YUMBL]

Thanks! The DDI may need a revisit with what I’ve learned.

[@robertcherman]

I play totally different than any of they KZbinrs I watch. Most of my interchanges are done in away where pedestrians are not walking there, to even have to worry about it. I break almost every rule the KZbinrs say and it still seems to work. One thought I never see people bring up. You might think by adding more businesses and such that it will get busier. But what happens is. If you have an intersection and you have 3 choices, and they are only picking one choice, add stuff to the other directions to get the traffic to want to go that way too. What happens is, lets say in a particular area on the road 10 cars can fit. If those 10 cars are only going right, you will sometimes get a bottleneck, because that means all 10 cars are going right. If you have stuff going to the left and to the right. Those same 10 cars, 5 will want to go right and 5 will want to go left. And then in turn if you have stuff straight ahead, and to the left and right, those 10 cars now have 3 options. Which makes it so 3 cars are going left, 3 are going right, and 3 are going straight and that left over goes whichever way. I am playing without mods right now, except for 25 tile because I already filled out the 9 tile. Here is just another random tip. I have a lot of interchanges where the single one way high way meet up. And, at that connection cars would sometimes block each other. So, it would be 1-way + 1-way going into a 2-way. This way they were always getting jammed up. I added a 3-way, so it was 1-way + 1+way going into a 3-way, and I was still having that same problem. It wasn't until I put a 4-way did it work without jamming any cars up. So, when they come off the ramp and the diverge together. If the car on the left one way wants to go right and the car on the right wants to go left. Instead of jamming at the intersection with 2 or 3 lanes, the 4 lane gave them 2 extra lanes in the middle to change without jamming each other, and if they did meet, they will just drive through each other.

[@JoshuaHere]

For pedestrians I would either make a bridge in the middle of the two other bridges meaning they'd have to cross twice (least amount possible in this setup) or preferably just make seperate bridges at other points over the highway. Because you can take note of already existent cims walking to see points of interests on both sides and have a more natural route.

[@YUMBL]

Great ideas!

[@daniellewis984]

DDIs are superior when the crossing double-light direction is a feeder road to the unstopped highway from/to both directions. The CFL is superior when all 4 directions penalize left turns but never straight traffic.

[@YUMBL]

There's a DDI in Calgary over McCleod Trail (AKA Calgary's Second largest parking lot, the first being Deerfoot Trail), and to be perfectly honest, IRL I hate them as a driver. Out of all the times where I've had a near-miss in Calgary, 90% of them have been here (people running yellows/reds, cutting people off, etc). In-game, it's beautiful. Wonderful job.

[@Bendigo1]

I use asset editor to make a 6 lane road with reversed lane directions to make it look more realistic. Instead of 2 separate roads over the highway there is only 1. Then I join the ends with a 4x4 or 5x5 curve into a 6 lane normal road. I like 12m heights on my overpasses.

Great idea! I have yet to mess with the network asset editor.

[@robertcherman]

And I didn't say this, I like your videos. I have learned a few things from you, a few things from Biffa and a few things from City Planner Plays. Probably the 3 Cities Skyline KZbinrs I actually get into watching.

[@gkcl1]

This is a response from a truck driver to your height argument, the 10m that you talk about is from the ground to the road surface, your bridge has an extra 2-3m of concrete and steel underneath it, taking the belly of the bridge to about 7m above the highway, standard truck height (in New Zealand at least) is 4.3m, which gives the truck a comfortable 2.7m clearance overhead. Using all the same measurements, if your bridge height was 6m, that would make the underside 3m, and would shave 1.3m off the top of a truck, which includes the drivers head. TD;DR, 10m is a good height

[@YUMBL]

I very much agree! Cities: Skylines does not measure from the bottom of the overpass like real places have to. 10m looks good here, but it could also be a bit less.

[@RandomGuyOnYoutube601]

@@YUMBL 10m is a good height. I believe vanilla minimum height is 8m.

[@YUMBL]

My mods and assets are linked in my about, but much of what i do is outlined in my videos :)

[@timvanarsdel]

10:50 I think what some commenters mean by 6 meters is that they'll build the underpass road at -6m, and the overpass road that crosses perpendicularly at +6m, so you still get a 12m difference between the two (less the thickness of the concrete).

[@YUMBL]

I wish that were the case. It’s generally people stating the standard height requirement of overpasses in their region and assuming Cities measures from the lower surface to to bottom of the overpass. I respect you giving people the benefit of the doubt though :)

[@Eugensson]

This is very common in the Netherlands (slightly differently configured with more straight roads and T-junctions). However in the Netherlands it is preferred to have overpass elevated due to the high ground water levels. So I think it is important for realism to avoid building underpasses when constructing near the seashore.

[@marcelschellekens6386]

if you make an entrance / exit at your motorway and change the rest of the entrance / exit ramps in a two way, you no longer need traffic lights. takes a little more space but it is just as beautiful

[@nilsdock]

a suggestion, how about a: Single Point Diverging Diamond Interchange make it the same way you made the single point urban interchange it could solve the weaving issues with the DDI

[@YUMBL]

Interesting idea! I did a Single Point Parclo. Let me think on it!

[@Bluerazor52]

This Cities: Skylines DDI may have weaving issues, but all the DDIs I've ever driven in have no weaving needed. Enter correctly and you shouldn't need to change lanes. And the only people that ever need to stop other than yielding is those going straight or turning left.

[@YUMBL]

I chose the wrong word. Weaving is inaccurate. Traffic exiting the highway and turning left DOES have to change lanes and get around the traffic turning left ONTO the highway. Not a weave, but certainly not conflict free.

[@YUMBL]

Yes, but no DCMI has ever been built. I think weaving the roads is probably impractical to construct.

[@Ricksdetrix]

18:43 what mod is causing the drivers to merge lanes more smoothly!? I NEED IT

[@YUMBL]

Check out my video about “node controller”

[@AlMcpherson79]

would you not need the node in the middle if you lane-managed the from-highway-going-left so that traffic could go directly into the middle lane of the overpass (splitting at the light) from the ramp which, of course, assumes you made the left-turning ramp traffic-lighted linked with the cross point? There's a vid on a real DDI and I can't remember if the overpass is two or three lanes anyway

[@YUMBL]

Yes! You can certainly allow traffic to turn left into any lane.

[@tadman3]

I tend to divert peds by building a paralel collector to my arterial interchange. also try building ped overpasses, i treat them the same as my roads with grading and landscaping

[@unstop2910]

The way he said "trees and stuff" at 19:57 sounded like Bill Wurtz

[@YUMBL]

The trees and stuff are a deadly laser

[@RandomGuyOnYoutube601]

Nice! One problem with diverging diamond is the weaving of the traffic on the overpass. But if you make a space between both sides of the overpass and make a clover ramps to the inner sides of the overpass then you get no weaving and the interchange can be incredibly compact. I am not sure why no one uses this in real life. I use these in my cities quite a bit.

[@YUMBL]

I’ve definitely found it hard to do well. Lots of nodes that close together usually look like a mess. I appreciate it dude!

[@DerBeppone]

To be fair, that road also looks like it is allready around 5 units thick. So, since the height is allways messured from road surface, it makes sense to measure in more space. After all we don't have got the luxury of technical planning such projects, where you would draw in every relevant messurement, like from bottom level to underside of a bridge.

[@YUMBL]

Bingo. Ive been told by many that 10-12m is too high. In Cities it clearly is not.

[@Panma98]

One thing I'd personally change is the angle of the on/off ramps, as you can see at 20:02 the green truck in the bottom right has to slow down before going on the highway due to what I assume is the angle. (they have their own lane, so shouldn't have any reason to slow down?). Although I'm no road person, I imagine that in real life you'd want to have as little unnecessary breaking as possible.

[@YUMBL]

I dint think it slowed down. The highway ramps have a lower speed limit by default. Look at all the cars going down it

quite a beautiful build. very nice even before the landscaping and lines. Have you worked with a "divergent diamond" where the divergent roads are inclined so that the traffic lights are replaced with an underpass for the cross over?

[@YUMBL]

I absolutely have! It’s called a “Double Crossover Merging Interchange” (DCMI). It exists in Cities Skylines, but none have been built on earth yet. It would be just as effective as a stack (free flowing), but probably at least as expensive to build. Beautiful design though!

[@MelbourneMaster]

Beautiful. But I must say I find it quite strange that the 2 overpass roads are switched in terms of direction. Normally you would make so that the cars drive on the right side of the road, when going straight. You have 2 roads beside each other with the left one going straight (compared to the 2 roads underneath). Maybe thats just how a diamond works, but this would definitely annoy the perfectionist in me lol. Is there no way of making them drive on the right road going and not left? 13:07 you can see it here how you have the directions opposite of what is considered normal.

[@YUMBL]

Look up how a “diverging diamond” works. The switching sides is what makes conflict free left turns possible.

[@destynnee]

This is a great way to create this interchange. I am horrible at making my own, so I always get them off of the workshop.

Realistically, it seems too prone for accidents at the twists on both ends. I would raise another level for the cars to go straight and the middle level for the turn. With the raised level, the middle level can branch to the other ramp in case one makes a wrong exit, they can get back to the highway right away.

No. Data supports the safety of this compared to many other interchanges. Massively.

Yooou knob.😂I said it to the car that did the weird thing at the time when you started to do traffic manager

[@FrodeLøtvedt]

I built it, but you have to post a tutorial on how to set up timed traffic lights. Please!

[@Stubones999]

Make sure to include a power backup generator, since this "design" without powered lights is quite dangerous... Second, if you make the overpass bridges two lanes wide, you don't have the merge issue. They did this design near my home (in hurricane zone) without a generator. They put lights at the ends of the offramps as well. The idiots that designed ours planted palm trees that blocked the view of the red lights in the middle of the interchange. It also really confuses foot traffic crossing the bridges, since they cross to the center and then back out to the side of the road for the sidewalks. They also marked the traffic lanes at the outside of the curves, not the inside. So, anyone who is going too fast in the marked lanes will hit the curb or wall! I always drive the inside of the curves, despite the markings. I would have preferred the DDI with two tunnels and zero lights. None of the locals likes this intersection, so it was put here against our objections.

[@tonymakarewicz5058]

What do you use to make your interchanges have those extra lines ( like the no drive zones

[@YUMBL]

It’s called “intersection marking tool”. I have another video on how to use it :)

[@LegionKilo]

Yumble, I need to know how to make the perfect hydro power dam. I'm an XBOX player, so it's probably a little different on game consoles, but still. The road stuff has been hella useful.

[@ravenmooore]

Hii how come the texture of your grass and 'hillside' look different from mine in Vanilla... is this a different texture mod or something? Thank you~! nice guide i will try this one also

[@YUMBL]

Its called the “map theme”. It controls all the map textures.

[@markknudsen1755]

Huh.. I never thought of using highway for the road. Or doing it this way! I use the standard 2 and 3 Lane One Way road (3 lane is for bridge). Then make a cross "X". Then take 2 LOW back to the Avenue. Though... I also have yet to download lane marking and node control. I'll have to try the way you showed!

[@YUMBL]

Highway is nice because traffic manager has a setting called “highway merging and splitting rules” or something like that. It can help a lot with interchanges. It’s the reason i don’t have to lane manage every highway connection. Just the ones to the arterial. intersection marking tool and node controller make it look much better!

[@markknudsen1755]

@@YUMBL ahh!! Okay that makes sense. Guess it just seems sorta odd to me. I have to watch again. But how'd you take care of the pedestrian issue as a "walk around".

[@YUMBL]

Is the three lane one way you use from the “network extensions 2” pack? The pedestrians have a crossing nearby. Theres a second DDI in the city that i haven’t solved yet, but id like to keep people out of it as much as possible

[@markknudsen1755]

@@YUMBL yea, i have the extension with the extra roads and all. Haha yea it makes things interesting trying to figure out the best way to help pedestrians in certain areas doesn't it?

[@akana_]

@YUMBLtv Question: would the overpass on this DDI encounter weaving in a similar fashion to a cloverleaf interchange, thus hindering efficiency? That is my only and sole concern regarding the use of DDIs in high traffic volumes.

[@YUMBL]

It would, but the lights solve it. Irl i also think that the merge is handled differently lane math wise. Imagine two lanes going over the overpass and the right one is dedicated to exiting. The left is thru. No weave, just merging for cars leaving the highway. Hope that makes sense!

[@akana_]

@@YUMBL Thanks for the explanation, makes perfect sense now that you explained it. One of your best traits is that you can make basically anything make sense haha.

[@Mike23443]

It's not really so much better than normal for a game, but in real lif it's supposed to lower accident risk. Personally I think this ain't anything a roundabout couldn't fix. What you can do in cities skylines is remove the cross altogether and make it a twist over/under pass rather than an interchange.

[@YUMBL]

This has a much higher capacity than a roundabout, or roundabout interchange. Thats called a DCMI. Its still an interchange.

[@-RizonGaming-]

I removed an interchange that had 2 roundabouts within it for this.

[@magno_pseudonym]

you can also do sloping with network multitool

[@DJinaShoebox]

Great channel dude!!

[@YUMBL]

Thanks a lot! :)

[@Overcrox]

Someone might have already asked this, but is there a reason to add lights for the people coming off the highway? I don't see why they couldn't merge onto the bridge and just stop at the crossover intersection.

[@YUMBL]

It was something of an experiment. I may redo this with new considerations in mind. You’re not wrong though.

[@ninjanerdstudent6937]

How come these tutorials feature roads in the middle of nowhere, and they are never a part of a bustling city?

[@YUMBL]

This one is actually part of a city.

[@gottawon6415]

Nice interchange, just curious what road texture mod you used and does it work for all roads, including roads from all the DLC's?

[@YUMBL]

I have a video called “dark roads” that explains it!

[@Saucirossi30]

Can you do a right of way instead of the lights for the left hand turns? Had a DDI in a city i lived in and it didn't have more than the two lights.

[@YUMBL]

Pretty much definitely. I was having issues with the traffic exiting the highway weaving severely with the traffic crossing traffic

[@TiGGowich]

This is great, but the crossing at the end of the overpass is a bit meh isn't it? I mean I know it only works like that but I imagine that would cause some trouble

[@Ramotttholl]

when i first made it in Cities skylines i didn't mind realism that much so i went for a small ugly bridge/tunnel to replace the intersections so there wouln't be cars crossing eachother at all.

[@YUMBL]

Thats called a “dcmi”.

[@zaixai9441]

Looks good.

[@Crogatho]

What is that road texture you're using? I've been looking all over the internet for dark pavement

[@YUMBL]

I have a video called “dark roads” that explains how to do it :)

[@northwest28]

Can you please make these beautiful interchanges in the workshop!

[@YUMBL]

This one is :)

[@northwest28]

@@YUMBL lol just as you replied I was watching another video!

[@YUMBL]

I’m glad you like them :)

[@davidroddini1512]

How about a center turn overpass? Basically the three lanes in each direction split. The right lane becomes a slip lane that bypasses the intersection. The middle lanes meet at a two phase intersection with north/south traffic going straight through on one phase and east/west traffic on the other. The left lanes in each direction ramp up to a grade separated intersection with two phase signaling. One phase allows north/south traffic to make lefts simultaneously; the other phase allows east/west traffic to make lefts simultaneously. The exit ramps from the grade separated intersection merge in from the left.

[@YUMBL]

I may have to see it to understand the shape and the grade separation. Sounds well thought out though!

[@humphreychannel582]

Could you not do this set up but make it so you don’t need any lights by keeping one side elevated over the other where the lanes swap to the other side?

[@YUMBL]

Yes. Thats a different interchange though. Its called a “double crossover merging interchange” or DCMI. None exist in the world to my knowledge, and it would be used as a free flowing system interchange, not a service interchange.

[@Anti_Woke]

I usually use a height-separation of 12 for crossings. This is more than you need for normal roads but clears the electrical pylons on railways and trams (and probably trolley busses). If an intersection is entirely ground-level or raised I will usually provide underpasses for pedestrians, otherwise elevated walkways. One 'feature' I think is nice for larger intersections is also providing a cable-car crossing.

[@arealassassin]

Drainage. You made a pond. Does it even rain in CS?

[@YUMBL]

It rains, but it doesn’t influence water level on the map. I like to pretend the drainage is under the road, draining from the sides.

[@santanadrums]

Are you using any mod for shadows?

[@YUMBL]

Yes! Shadow strength adjuster.

[@BRLN1]

In some (actually most) videos you say a height distance of 10 is enough for the vehicles, but in others (at least one other) you say 12. Which is it actually?

[@YUMBL]

It depends on the road. 10 is fine for vanilla arterials, but some can go as low as 7.

[@PianoKwanMan]

Have you tried doing junctions on a bend?

[@YUMBL]

In my cities, yes. Not for the things i put in the workshop.

[@matthewyang7893]

I put pedestrian paths along, over, or under service interchanges

[@spatrompete2601]

I like the design of the road the dark colour what is this set called ?

[@YUMBL]

Roads color changer ++ is the mod. Most of the roads are stock
