No, you were not even remotely close. I'm here to see what you came up with this time and enjoy the next very calming 17 minutes.
I don't watch your videos to better play the game, I watch them because they're entertaining.
I’ll accept that. Thank you :)
That. I've not launched C:S in the last couple of years (W&R ftw), but these videos are just so soothing and satisfying :p
Same, i don’t even have the game but it is sooo calming and i love to see traffic fixes
@@lisakolde7436 Yeah same I don't own the game either xD
this might be the best put together cities skylines channel not even kidding
Much appreciated :)
The main part that sells it for me is that the creator (Yumbl), is creating content about concepts, ideas, and usage, that is centred on the idea and concept, rather than a playthrough with some tips and stuff like that hidden within that requires the watching of the whole video. I'm loving this channel. (Of course, there are still lets plays, but the aforementioned part really sells it).
@@DsYkX Sometimes on some channels, a tip is promised, and it's _very_ deeply buried, or even only hinted at. As you say, not an issue on this channel.
@@inyobill Definitely!!! I can of course bury my time reading articles and studies on real life road planning and the same in Cities: Skylines (Thanks Steam guides), but this is much more enjoyable! I do definitely still spend a lot of time reading up on it. This is interesting to me!
When Yumbl said 'go and fix your fundamental problems' I took that personally 😂
I'm both glad and devastated that I'm not the only one 😂
@@corysmith9975 😂 😂 😂
I was like - jeez that's going to take a while XD
Whenever we're in the car, my 3 year old daughter asks me "what road we on"? I've been telling her we're either on a little road, a medium road, or a big road.
It's never too early to learn about road hierarchy.
hahaha, she's gonna be a city planner when she grows up.
I tend to do grid cities and find that when I have a congested intersection, I do what Yumbl describes only to find that it lets so much traffic through, it just backs up the next intersection down the grid. You can combat this by doing this technique at every intersection all down the collector and sync all the timed traffic lights together. Sometimes I have 6, 7, or 8 intersections all synced together and the lights turn green first for all the cross traffic then for all the through traffic. Works really well most of the time.
7:00 If you type CTRL-S repeatedly, TM:PE will cycle thorough various options, including making only one side stick to the same lanes.
Wow, that's helpful! Thanks!
I think to certain people your videos can be used for therapy. They are so soothing. No bs, nice music, lovely narration, no trying to be hilarious, no shouting... Just a blissful video every upload.
Much appreciated :)
From what I've seen in this game, a single lane can provide huge capacity if the flow is uninterrupted. Multiple lane are only needed to distritube/collect the stream smoothly or -like in your example- as a buffer. A fully used 4lane highway is more likely a sign for a poor layout than for big demand.
Your video about the SPUI (single node version) made me try 5+3L junctions, the tutorial about timed traffic lights (with the "secret" cycles to clear the junctions) brought it to perfection. Those junctions have by far the best capacity/space I've seen, pure peak performance.
Thanks for your tipps and inspiration!

Thank you. I finally understand high capacity round-a-bouts after playing them for about a year now.
Awesome and informative as always!
I just want to say that your channel is GREAT, your tips are great and sometimes you say the basic stuff that should be obvious but my stupid ass didnt think about (not talking about this video specifically but your whole content) it has helped me a lot
I just bought Cities Skylines and was very overwhelmed by traffic and transit and my first city, well let's just say it was a technical failure. I've watched a lot of your videos and have a better idea on where to start, what to build, what roads to use and even mods. Thanks for not being condescending in your videos like some others are, thanks for taking the time to make them because you have def helped me.
Glad to help! :)
The last one 4+2 does not allow a 360. And it is needed sometimes (even on this game 😁).
I also do a variant of this one giving the interior lane juste the right to go front or on the next one, and do the same until I am on the exterior line, giving the obligation to exit the roundabout. It does work well I must say. 😁👍🏼
Anyway, I stay totally impressed by your technique an knowledge.
I must say that this game makes me happy almost only on managing traffic.
I might think about this for my next work journey 🙌🏼
2:31 "is everybody in the groove" HAHAH
Perfect topic for a new cities skylines video considering recent updates
A good summary and introduction to your channel.
It was a good recap for me as I have a problem junction and was about to go nuclear when a simple timed traffic light will suffice.
thx for the content! one thing i notice in real cities that i never see anyone use game, and this is way off topic but, one way streets downtown. every big city and even medium and small cities have one way roads but i never see anyone use them in this game. i love your content, i do kinda miss yumbledor here in youtube, but i’ll live, THX!
Never comment, but your videos are just wonderful. Thank you, so helpful!
Would love a video looking at 'assymetrical junctions'. Where the angle is not 90 degrees, and traffic slows right down trying to turn a sharp turn - how to deal with this (without rearranging the city) Or 5 way intersections - is it a simple as 4+2? Wonderful content as always!!
In these heavy density situations, I’ve also gotten good results with an asymmetrical setup that has a dedicated overpass for the straight lanes of the primary road… pretty sure I got that idea from you, and then again when Biffa used it in one of his Mississipitea traffic videos
Biff borrowed the idea from that Yumble tutorial, I believe.
@@inyobill more like comments imo
@@inyobill Well I think they both looked at the mod and followed the instructions. I do think Biffa looked up Yumbl's vids after that tho, he mentioned it.
But the quadrant interchange Biffa used in Mississipitea ended up looking unrealistic, both his Mississipitea and Blightea-on-the-Wold looks unrealistic.
Biffa's cities always end up having streetlights poking through the road above, highway bridges being too low, often causing double decker buses and trucks to clip through bridges.
@@automation7295 "Unrealistic"? Where there are mainline Rail lines with grades in excess of 3%? Where roads take up exorbitant area, relative to other assets? Really? Can we get more picky?
I'm just another person here for the serene satisfaction from watching clean intersections, I don't even play the game (yet)
Very interesting, as always.
Excellent video. I would say a heavily optimized traffic light with 5+3 lanes is one step above the final roundabout, but yeah if even that is not cutting it then a compact interchange like the SPUI makes a lot of sense. Or you can create some sort of bypass with Vanilla Overpass or some other method.
You are making me want to get back into Cities Skylines so I can test out all these tricks.
More here just because I like your videos, not having traffic issues thanks to you and Biffa. :) ..or should I say "yet"?
Just wanted to add if you only wanted trafffic to stick to their lane on one side, you can switch through options with the same Ctrl-S binding that you use to set it up, should go from both sides, to one, to the other, to none.
I was hoping that this would be a more in-depth explanation of the building blocks that go into these fixes. Like:
A: How do you set up a turning lane? Why would you want turning lanes? When and where do you want turning lanes? When and where do you want a merging lane?
B: What are lane connectors for? When and where do you want lane connectors? When and where do you NOT want lane connectors?
C: What kinds of traffic lights are there? What is the difference? Why is the TM:PE auto-setup traffic light the best in most situations?
D: What do you look out for when adjusting the timings of TM:PE traffic lights? When would you want to increase the times? When have you gone too far increasing the times/ when would you want to decrease the times?
E: When and where are roundabouts useful? Which TM:PE settings should you use on a typical roundabout? How do you calculate how many lanes to have on the roundabout and how many on the approach?
This video is more like a "Top 5 solutions for fixing an intersection".
in Scotland we have 5 and 6 lane roundabouts with traffic lights. They are very good for heavy traffic service interchanges
You're wrong. I am here due to finally getting inspiration to build after about 3 months off, started 2 days ago and bam, update. All my mods broken. So I am here for my fix of Cities Skylines, been a while since I have watched due to lack of Cities inspiration lately. I need inspiration to keep interested!
You’re wrong?
@@YUMBL Just the "let me guess why you're here part". nothing by it :)
One trick I like that is similar to your "blowing out the intersection" involves much the same tactics except a 3+2 is used with the dedicated right lanes being able to "go on red". It wouldn't be as useful with that much traffic though. I think I even saw you do it in another video, but not sure it was you. It does involve using lane connector to force left and straight turns into the inboard lane so right turn won't be affected. I will give this version a try next time I am having trouble in a heavier traffic situation! I think its more useful like in your PARCLO video. I think I figured out where I saw it...
That last roundabout iteration would be absolute chaos in real life.
It's not too bad, there's pretty similar setups outside Wickenburg AZ and outside Vegas NV and they are kinda stressful as a driver the first time but once you've done it it's less stressful than roundabouts where you're not sure what anyone is trying to do, at least in my experience.
The biggest mistake I see with the roundabout portion is the roundabout is just too small. Like with lane mathematics and road hierarchy - road size, intersection size, and roundabout size really matters. Making the roundabout physically larger and thus increasing the distance between nodes helps a ton. When nodes are too close together traffic "hesitates" and won't move from one node to the next till it's clear. Once you do that there is no need to go with a 5 lane roundabout and force lanes. Just bump it up in diameter so the nodes are further apart and traffic will naturally flow faster even when there are less lanes.
Unless the traffic is unusually high in that specific directions, dedicated right turn lanes on intersections might not be necessary. You often see this in real life as well, where the intersection has a dedicated left turn and light phase for left turns only, but the rightmost lane is both for traffic turning right and going straight. Granted, in C:S the difference is not that huge as a 2+3 lane street takes up the same amount of space as a 2+4 lane.
Absolutely. I just didnt want to cover every iteration of asymmetric roads. 4+2 is the sweet spot imo, but of course an intersection is very flexible.
personally with timed traffic lights, i usually have slip ramps for right turning traffic and i usually remove the right turn arrow so i can have 2 left turn lanes and 2 straight on lanes.
the problem with me is once i see a red area, i start having a form of OCD and try to get it down to a orange or a light yellow. and usually when that happens, i often don't do well at all. lol
Good day.
Tip of the day.
CTRL+S (press "S" twice) it will select 1 side and press it again it select the other side...
Cheers
Wassup yumbltv? I love your videos they help me so much
Thank you, glad to help!
This video kinda hints on why in reality, timed traffic lights are the usual choice for busy junctions. That roundabout is too space consuming and for real people, all these lanes will surely cause a serious mess.
Far from it. In reality, roudabouts are amazing for one reason: safety. They remove a lot of conflicts and slow traffic down. That's intentional and reduces accidents. However, Cities Skylines doesn't care about safety, so the slow down impacts the traffic in game without a worthwhile payoff.
“Busy junctions” mean different things in different places. Most busy junctions near me could not be replaced with a roundabout without some miracle-level traffic reduction. Car dependency is real.
Macro fixes (other video) are usually better than what's being proposed here. Especially since typically when you're in a situation where you need to make one of these fixes, it's in a part of the city where there's no space. Also, everything here seems to rely on traffic manager -- even the basic roundabouts.
The two are not mutually exclusive. Always start with macro fixes is the message here.
YUMBLtv is the king of traffic management. Not even a close second.
Dude I'd really like to see you making traffic fixing series similar to what Biffa and Sam bur did, because it seems to me you know a lot more about it
People dont tend to watch my series. I get asked a lot, but many more show up for videos about learning the game.
@@YUMBL He's talking about traffic fixing series like Biffa used to do, not let's play, I bet many watch all your traffic fixes of different submissons!
@@YUMBL Yeah I think a traffic fix series from you would get massive attention! Especially if you do it on some massive build which will have epic traffic issues like something with 500k+ population and the More Vehicles mod. That’d be completely new ground.
“Oh look, a new yumbl vid…”
“YUMBL Dies.”
In the last aroundabut, it would have been great if TM could let the right lane go through regardless of the yield sign. it is essentially a slip lane for right turn traffic. I guess you could do a 4 lane roundabout with a slip lane, but that's more steps.
It is not conflict free. The thru and left turning traffic uses it as well.
you could probably clear quite a bit of the traffic if you used a 3 lane roundabout while also having the cars enter at a shallower angle since irl you wouldnt enter at a 90 degree angle otherwise you take longer to enter and get round since you have to slow down more
no, i'm here because you uploaded a vid 🤣
In your "turbo roundabout", the junctions permissions aren't right - you can see the cars approaching are all stopping rather than flowing. It's like they've got stop signs or something. It's certainly possible to have them enter the junction more smoothly than that without having the "enter blocked junction" ticked!
Infact, you can see the stop at @15:40 (start at 15:30 to see them stop) - they've an empty junction but halt anyway.
On the last roundabout would it be valuable or possible to have an option for entries to turn all the way around? I've gone through roundabouts like that where I've gotten confused and picked the wrong lane and when it's an interchange at a highway entry it can be a truly.... adventurous mistake. I'm always thankful for the option to circle back around and try again!
You could but at the cost of capacity and the need to add an extra lane.
You were wrong, and unfortunately not even close
I don't actually even own C:S
I just come here to learn the general ideas of Civil and Highway engineering, and because you're entertaining while teaching us
I've found from experience that a 3+1 turbo roundabout can handle about the same amount of traffic as a 4+2 light if you set it up properly. The 4+2 roundabout works, but it's so unrealistic that I can't bring myself to use it.
Yea, i dont like the 4+2 result either. I just didnt want people thinking it was being misrepresented.
The roundabout: You don't actually need Traffic Manager. Under junctions in the traffic routes tool under your overlay menu, you can disable the traffic light and then add stop signs, which serve as yield after stopping. You do want to place a highway there if you don't intend on having crossings through the centre, or make your own route for pedestrians so they do not cross the road. (Or pathfinding may not even happen due to the shape)
Traffic still wont “enter blocked junction” within the roundabout though. Its really bad
@@YUMBL 2 thinks I'd like to clarify:
- I'm referring to the first small roundabout, if you make that big of a roundabout with that many lanes, this isn't for you.
- This is for people who play vanilla. TM:PE is an essential mod no matter what. Hands down.
Well, no, I'm here because you make cool videos.
If I have a problem intersection, I just ban private cars and that fixes things :) EU style.
Love your videos.
At 4:28, you have a huge selection of road types. What UI mod (?) did you use to get the game to show it to you in this manner?
Thank you! “Better roads toolbar” is the mod
do these American roads change color if we use road options?
For the 4+2 roundabout, would it be more efficient for the traffic taking the 3rd exit, to exit into the 'fast lane' instead of the 'slow lane'? (In the version shown in the vid) the traffic on the opposite side taking their 1st exit is also exiting into the slow lane, and the slow lane is also being occupied by the through traffic from the 'right'. This puts 3 lanes of traffic into the slow lane and only 1 lane into the fast lane. Whereas, if the traffic taking the 3rd exit uses the fast lane instead it's split evenly and I can't see how that would disrupt the flow of traffic through the roundabout. (Correct me if I'm wrong :) )
As you look at the colours, the dark green would merge with the peach instead of the lime.
I think the war on traffic management is over
Biffa is slowly leaving roundabouts and Yumbl is slowly accepting roundabouts
Nature is healing.
Like the old man said: “Luke, you’re going to find that many of the truths we cling to depend greatly on our own point of view.”
Hello there!
00:10 lol I don't even own the game. I just enjoy watching the problem solving and designs people have.
I think you mentioned the problem right at the start. 'intersection at the START of your city'. Real cities don't have starts they have edges best way to build a city in game in my opinion is start with a ring road using a national road and start connecting to it with T junctions in many directions.
Then as the city grows you can upgrade the road connections
But the game does have starts and its almost always a single highway connection. I agree that a ring is best, but thats rarely how maps start.
Sometimes these videos are great.
Other times I hate playing on Xbox.
"Blowing Out the intersection" is a term I heard on City Nerd's video on 'Stroads'
Same here. I found it perfectly apt :)
@@YUMBL no pork chops in your interactions though 🤣🤣
Its funny how the traffic in my city automatically behave the same as how the turbo roundabout is set up, but I haven't even set up the roundabouts to be turbo roundabouts
Loved the videos, but the 1st of this series gave mostly vanilla solutions. I've watched a bunch of videos and still have the 4 lane intersection problem, but this video essentially gave me nothing, considering I don't have mods. Is there no vanilla solution?
You’ll want a well designed transit system.
In the last roundabout, what if someone going, say, N-S but needs to head back up N...? They don't have that option with the lane connectors, right?
Correct. They should find a legal place to turn around.
@@YUMBL Sorry, didn't know that wasn't legal in the States. In my country it is.
It is generally legal, but if the markings disallow it you shouldnt. Such is the case in some turbo roundabout designs.
the timed traffic lights confuse the heck out of me
you should create Timed traffic light using Alt+Control+click here to create alternate timed traffic light. because most cars want to go straight than to turn left.
this will create priority/left turn cycles.
Hey Kian! I’ve never tried it. Sounds simple enough. Does it change by “more waiting than driving”?
@@YUMBL yes
Makes sense. Thanks for everything you do in the community :)
Does anyone know what are conditions for people choosing one mode of transport over another?
I think age, income, education, and type of housing are all factors. I’m not sure of the specifics though
Biffa will be pleased.
I'd love to see some vanilla solutions, because I can't play with mods.
Actually I'd like to see how you would handle an intersection between a single lane road (1 go 1 come), a dual lane avenue (2 go 2 come) and a railroad track.
Vanilla way.
How do you get the 4+2 roads? Is it a mod?
Theyre an asset from the steam workshop.
what mod is the 4lane/2lane road??
steamcommunity.com/sharedfiles/filedetails/?id=2583394094
In my city the traffic always goes between 68-71%, when I turn off de-spawning, it went down to where it goes between 65-68%. Traffic is busy, but it is always flowing. The city has a lot of high-density zoning. Could it just be that traffic is busy and the percentages are alright?
That may be. If everything is functional and not backing up it’s not a problem. Have you already implemented transit?
@@YUMBL Yes. Mostly Buses and Subway.
where do i get the 4+2 road in the workshop?
steamcommunity.com/sharedfiles/filedetails/?id=2181746799 is one. Google is the way to go for searching the workshop!
steamcommunity.com/sharedfiles/filedetails/?id=2583394094
how do you get your vanila roads to look that way? what mod is it?
Road options
@@YUMBL Thanks!
I learned something once. I forget what it was.
I was able to fix my traffic by converting my city’s central boulevard into a modded 12 lane expressway
Between this channel and Biffa's channel I have learned an insane amount on how to lay out my roads. Some little tweaks need to be made in some areas, but City number 2 and 3 should be extremely efficient
What mod are you using for the 4+2 road? I couldn't find it and your mods collection is just too big 😅
Here you go :) steamcommunity.com/sharedfiles/filedetails/?id=2583394094
@@YUMBL Awesome, thanks a lot! :)
More solutions without any mods would be nice.
What about your city series ?
Still going!
for the turbo roundabout I personally don't see the need of having a 4 lane into 5 on the roundabout for a 4-way intersection, I always do, x-way intersection, then all roads leading are x-1 and on the roundabout itself is x, so basically, for a 4-way intersection, have 3 lanes coming into the roundabout, 4 in the roundabout, having such big ones seem like unnecessary conflict points, unless you choose to sort the traffic with the traffic signs in TM:PE (i.e. transport truck only road) or to have a road come back around, as the outer lane is best to keep as dedicated right turn for the road it's connected to
I was just matching the volume handled by a 4+2 road
@@YUMBL ahhh that's fair
Surely the magic roundabout comes before the interchange?
Still a rather low traffic solution as it turns out.
You need lane mathematics and dedicated turning lanes. This fixes MOST traffic issues. Then you can start concentrating on getting less people to drive. Though a large industry is always a nightmare no matter what.
I think of it in reverse, but both are important.
@@YUMBL true but unless you are playing in sandbox mode you don't have a lot of public transport options at the start. So when making roads, lane math and turning lanes can help you get ahead of the problem.
Yumbl for Secretary of Transportation
You say we need traffic manager to make the roundabout - why is that?
The “ Blow out intersection “. Is the standard intersection here in Abu Dhabi , most roads are 6 lane and 80 kph.
How do you have so much traffic flowing with 0 population? Is this some mod that allows traffic spawning for testing?
I’m using “interchange test map”. Its all dummy (intercity) traffic.
@@YUMBL 👍Great I'll use that. Thanks for the videos, really appreciate all your hard work.
How did you adjust the traffic in this game
No traffic simulation adjustments were made here.
@@YUMBL can you get some sort of traffic simulator to increase and decrease the cars in this game?
I think so, but ive never needed to.

One thing I've heard/read over the years is the AI has issues with more than 4 lane roundabouts.
I dont think so. You do have to manage it carefully though.
Hence, the lane connections using Traffic Manager.
0:12 you are not close at all, I don't even play this game 😂
I'm here to see whether or not anyone else is experiencing what I am, with the Parks and Promenades update corrupting their entire game... I can't even load to the home screen anymore.

If Americans need any more proof that you drive on the wrong side of the road here it is, your roundabouts go COUNTER clockwise 😂
15:40 Americans couldn't handle this many lanes 🤣 I can't tell you how many times I've had to slam on the breaks on the highway because someone wasn't intelligent enough not to come to a dead stop over the fact two lanes had to swerve slightly to one side to make room for an overpass support; 5 lanes is too much for the average American mind.
This roundabout is dangerous irl no matter where it is.
I only build turbine roundabouts. No other variation makes sense to me. 🤷🏻♂️
Am I crazy, or did you already do this entire video once?
I dont think so. Lmk if you find it 😅

Great video. Except its useless for anyone on console
The first video will benefit them much more
If you reached that last point you might also be needing bigger trains or metro leading into bus/tram distribuitors. Having mass transit help out can keep the traffic manageable for longer.
Wrong, I clicked on this video because of the roundabout thumbnail.
A move of taste.
From what I've seen in this game, a single lane can provide huge capacity if the flow is uninterrupted. Multiple lane are only needed to distritube/collect the stream smoothly or (like in your example) as a buffer. A fully used 4lane highway is more likely a sign for a poor layout than for big demand.
Your video about the SPUI (single node version) made me try 5+3L junctions, the tutorial about timed traffic lights (with the "secret" cycles to clear the junctions) brought it to perfection. Those junctions have by far the best capacity/space I've seen, pure peak performance.
