[@Pharenir]

It's honestly baffling to me why they didn't include the function to manually change lane settings in the base game. With a deeper focus on traffic compared to the first game this seems like an obvious thing, why do we need mods for that? Traffic management would've been so much easier with that function alone.

[@BiffaPlaysCitiesSkylines]

True, but I guess because there is probably a list with 10 million things on that would be great to have in a game, but you have to stop somewherre and then maybe add things like this at a later date :-)

[@michelanvalo]

If I had to guess it's coming in a DLC/Update sometime in the next few years. They took a lot of popular mods and made them into the base game for C:S1, I'm sure they'll do the same for C:S2.

[@Pharenir]

@Biffa that's certainly true. But especially for a second entry in a series I'd look into the most popular mods for the first game and (at least try) to implement that. And of this moment that's (according to steam) Move It, Precision Engineering (which they mostly implemented) and TM:PE. Even more so when you focus more on the simulation of things and 'better' traffic simulation. I can understand and fully support that they didn't include all the QOL mods for detailing etc. but I honestly expected better traffic control. @michelanvalo and with Paradox at the helm I'd guess we'd have to pay a pretty sum for that DLC...

[@danielwilson6323]

Surely it’s a performance limitation? It would definitely increase the complexity of route planning, and probably doesn’t scale well especially on consoles. CS2 already has significant issues with the agent simulation at high populations

[@Pharenir]

@@danielwilson6323 very much doubt it would have much of an influence on performance. Especially since there is already a 'light' version of this in the game: banning left/straight/right traffic for an entire street. And to be perfectly honest, I'm tired of console limitations constricting the decisions for these kinds of games. It's a complex simulation, imho it doesn't belong on consoles which are inherently limited in controlling these kinds of games.

[@DrakeGamer85]

As I stated in the chat, let's see you testing intersections, where the central column of traffic on roads use a bridge/tunnel section.

[@BiffaPlaysCitiesSkylines]

Indeed, in a future episode! :-)

[@faustinpippin9208]

I build something like this in cs1, a compact stacked intrchange with "vanilla overpass" but i had to "ban" turning left (to avoid building the left turn ramps) in a grid pattern city it wasn't a problem

[@icsde2002]

Biffa, for junctions like the last one, I've done it last year, and I've found out if you make it normal, as in a 4 way junction, add the traffic lights select the "protected left turn" or the "split phasing", after that upgrade one of the road into a highway going in and then draw a highway going out and then a highway going in, it will still remember the light the "advanced split phasing" or the "protected left turns" even if it wont show it in there as being an option or even a selected phase, it will function as intended. From my understanding, the traffic light will stay as it is unless you delete the junction and do 2 different roads in the same direction, I've a similar junction, but with 3 highways going in, 2 lanes each, 2 left,2 straight, 2 right. What you could do for a future testing episode is to test different types of junction like this and see which one would do the best for a traffic flow.

[@willcaine1208]

Hi, I'd just like to note for Mr. Biffa something important about the first intersection (which also applies in his city with the intersections he was having trouble with last episode). While unidirectional lane filling is the best technique for vanilla intersection flow and similar, e.g. under TMPE in CS1 or the regular Split Phasing with the TEM here in CS2; however, once you get to setups that make better use of lanes, like the advanced split phasing, the lane maths have to be applied slightly differently. Unidirectional lane filling is what Biffa does at 6:05 (6:35) and 31:14 (although here it is justified, because of the outgoing number of lanes in the intersection, which I will explain after), where all the incoming lanes are dedicated to one direction and attempt to fill all outgoing lanes. The significant difference is that with basic intersection flow, you imagine that all of the cars are going everywhere at once. A single use for each incoming lane and (ideally) a single entrance to each outgoing lane from the intersection means the cars don't have to merge and, in turn, optimises traffic flow. *On the other hand, with advanced intersection flow, it's important to consider each phase of traffic movement, rather than as if all the cars were going everywhere at once.* Once the lanes have been automatically set by the Lane Direction Tool within TEM, you can see at 4:30 that within a phase (the north phase there), all outgoing lanes of the crossed turn direction (west) are used, as the two crossed turning lanes and the single curb turn (left turn) lane from the opposite incoming direction (south) combine to fill all 3 lanes, and all outgoing lanes of the opposite direction (south) are used, as two are used by traffic from the north and one is used by left-turning traffic from the east. *This is the essence of advanced intersection flow, allowing for cars to split to the highest number of lanes to use the as much road as possible as effectively as possible.* You may be looking at the footage and notice that there are actually two left-turning lanes from the south direction, creating merging in the centre lane to the west outgoing; compare the lane markings to those at 6:40 when Biffa upgrades to 4 lanes. Now, the mathematics is perfect. Yes, it looks like there is overlap, but because traffic is phased properly, there is no forced merging, so it would run smoothly - the only overlaps within the same phase are where the 4 lanes goes down to three. This is due to the nature of asymmetrical roads. I could make a whole post just on how to properly apply them, but in essence it's adding a lane to an oncoming direction, meaning that lanes should also be added to the other outgoing directions of the intersection to accommodate the more spread-out cars; the asymmetric road should not be used just on its own. This will ensure that the phased lane mathematics works out properly (note: if multiple directions need asymmetric roads, extra lanes need not be added multiple times to the non-asymmetric directions, and the ultimate result should be that the roads that needed asymmetric actually get +1 lanes in both directions, so they don't actually end up asymmetric). Hope this makes sense and helps!

[@willcaine1208]

@ Yeah, I can give you an example of using asymmetrical roads. Imagine you have a 4-way intersection with 1 lane each direction where themajority of traffic is coming from the south. For left-hand drive, it would look like this: ⬆⬇ ➡ ➡ ⬅ ⬅ ⬆⬇ Now, because the traffic is coming from the south, let's add another to take pressure off of the single incoming south lane going all directions. Depending on how traffic is going, this could be to create a dedicated left/right lane if most traffic is heading in that direction (and have a shared straight and right or straight and left lane), or, if most traffic is going north, to create two straight lanes that northbound traffic can split into, effectively doubling throughput. Remember that to create the asymmetric incoming from the south, the outgoing in the other directions also need to accommodate. For our situation, let's say you have observed the intersection and most traffic wants to head north: ⬆⬆⬇ ➡ ➡ ⬅ ⬅ ⬆⬆⬇ By uniformly increasing the size of the intersection, now there are enough lanes to accommodate the newly throughput cars that you've allowed in. To do it otherwise, you allow more cars in, but without giving them a way out, congestion will remain the same or could even get worse.

[@dome_DBS]

I think that @Biffa had a point there whit the "u-turn" situation, and also all people complaining about car shifting lanes or waiting hours just to get a parking spot on the other side of the road...well: this is how real traffic works! Think about this next time that you're driving and just "stop a minute" to do something or you waste hours driving oround to find parking or you shift lane at the last second because you're distracted or just coise you've saw the other lane is empty or quiker. (I'm a driver and I've to say that this kind of traffic AI is one of the most realistic in sims history)

[@joeyjoeyremmers]

Hi Biffa, interesting video and helps a lot! But there actually is a six (and even 7) lane one-way road under the large road tab. That would making the last junction a little bit easier!

[@carriegarrisonvos4433]

It's amazing how well the last configuration worked with on both settings! You really do the science on all of this!! the only thing I could think of was underground otherwise, but it worked beautifully👏👏🤩

[@adamk8376]

When setting up the highway sections you should have used the parallel tool and then just upgraded the side you wanted to. Would have made it easier and looking better without turning the guidelines on and off.

[@SpiderBoat]

Waiting patiently like a Cim at an empty roundabout

[@Capt_Sam_J]

I would love to see a mod that replicates realistic constriction. When placing roads down it might take a few months of game time to complete it.

[@covishen]

One I would like to see is something on our east coast is called the "New Jersey jug handle". I won't explain it because Wikipedia has a very good description. It might be work experimentation.

[@Thromash]

Still baffles me that turning lights do not exist in this game. Would literally solve heaps of traffic issues but a mod is required for basic traffic control.

[@roybmanofmerlin]

In one of your CS1 cities you had raised turns that arose from the middle of the 2 roads and then came back down to rejoin in the middle of the 2 roads after the turn

[@stevieinselby]

It seems that the despawning is generally caused by gridlock when right-turning traffic blocks other traffic that blocks other traffic that blocks the right-turning traffic at the start of the sentence - which is pretty much inevitable if right-turning traffic doesn't get its own phase and there is no intergreen period. Adding a pedestrian phase would help to reduce this problem!

[@jameshg1900]

Another great and fascinating video Biffa. As a fellow Brit, I'd love to see you have a go at the appalling Roundabout + Traffic Lights that are everywhere in the UK, if only to show the rest of the world how dreadful they are.

[@nightware.]

So pretty much Traffic vanilla works perfectly but lacks split phasing, which is unfortunate, and I hope the devs will see this and figure out that this is the best fix for cars despawning and Add the split phasing into the game

[@flobiish]

In the final design, two of the left turns are overlapping in opposite directions. Moving the lanes over slightly so they don't block each other would increase traffic flow.

[@NotFlint]

Maybe it is overkill and missing the point because it would be to massiv for it to be considered an inner city crossing, but I guess if you try and turn the opposite straight ons into tunnels and turn the other two into overpasses, it wouldn't despawn anything because it hasn't any crossing traffic. To take it even further you could do 2 lanes for these roads so the splitting lefts and merching lefts get a dedicated lane aswell. With that setup the traffic light only has to handle the right hand turns.

[@jonblair5470]

Also in this setup the closest vehicle spawner to the vehicle after it’s spawned is the adjacent sides, that’s why most of your cars turn right and left. You’ll find if you zoom out the ones that end up going straight, are ones that would be stuck in line too long if they turned to the closest spawner, so they choose to go straight

[@rileywhetstone1755]

Nice demo of an Intersection in CS2, Thank You!

[@BiffaPlaysCitiesSkylines]

Glad you liked it!

[@SouthKoreanSanta]

Love seeing traffic flow in Cities Skylines 2. Hope you upload more often❤❤

[@BiffaPlaysCitiesSkylines]

More to come!

[@lyrrakell]

Very nice look at the various options available with the mod. I cannot remotely understand the reasoning behind their vanilla light behavior. Only the least busy intersections would work with the vanilla set up.

[@ManojSingh-bg9ue]

Hey Biffa, while making these permutation and combinations, can you also mention which one to use where or in which scenario? Also can you use something like these in your future city episodes so that we can see a real city skylines example?

[@BiffaPlaysCitiesSkylines]

I did mention the sort of things you need to consider in the video :-)

[@DarcyAllenStrong]

I really can’t wait until mods are built in the game so we can all use them! I kinda miss spending hours tweaking traffic lights with traffic manager. My last big CS1 city I build was down to around 13% with despawning turned off.

[@Kopa_Malphas]

NGL This traffic breakdown was wild.

[@Aqibalisyed]

Excellent video, Yumble must be taking notes 😜

[@ulysseslee9541]

And this is how a Busy Australian Intersection comes.

[@OlcayKaraday]

42:14 you can control the turning lanes in vanilla in this junction. Since these are all different roads, you can basicly forbid all other actions. For example, if you forbid right and left turn, you can get 3 lanes directly going straight through the junction. If you forbid left turn and going straight, you can get three lanes turning right.

[@OlcayKaraday]

Oh you did that like 10 seconds later 😂 I wrote before watching the remaining part 😂

[@christopherjunkins]

Wow Biffa, just wow. Amazing work as always, but that brain of yours... you might want to donate it to science after you pass LONG into the future (May you have a VERY long life :) )... amazing thoughts and processing.

[@BiffaPlaysCitiesSkylines]

😅 thankyou

[@christopherjunkins]

@@BiffaPlaysCitiesSkylines you are very much welcome.

[@TypicxlSortOfOdd]

While moving the nodes to the side roughly, you CAN drag to move them smoothly and evenly with the offset I believe. Correct me if I'm wrong.

[@aaronhedgesmusic]

Maybe next time you do the test with traffic on the right hand side of the road, since most of the world drives that way? Thanks 🙏 ❤

[@Tony-pb2gi]

Just watch the video in a mirror! :p

[@ihmss007]

Very helpful and I plan on using the vanilla highway junction in my city. Can you do this type of video for highway off/on ramps next? The ones in the game are massive and don't handle large volumes of traffic well. My Frankenstein off/on ramps gets rammed with traffic 😂. Thanks regardless and keep it up

[@trev8591]

Really interesting traffic experiment by the Mad Professor Biffa! Awesome, mate.

[@BiffaPlaysCitiesSkylines]

Thanks a lot!

[@carlosblanquer8628]

On some kind of intersections, these things are better resolved making the straight lanes down on a tunnel, or the turns to the right over a bridge. Traffic won't stop. One thing is having tiny space and you just have to stick on a cross (where you still can tunnel the straight lanes on the most busy direction), another is upgrading to a non-sense sum of lanes and abusrd traffic stops (USA is a big example of that)

[@MNSweet]

Im not saying you need to come back for season 10, I made peace with that a decade ago but please one cameo just to mess with X is all I ask.

[@lordsleepyhead]

Now I'd like to see how you get pedestrians around this monstrosity without making it ugly with pedestrian bridge spaghetti.

[@andresbonelli1826]

Maybe it'd be worth trying out only straight and left hand turn traffic at the intersection with a return after the intersection for the traffic that wanted to turn right just test it out

[@HerbertTowers]

Perhaps instead of saying:- "That's just how the game works" you should instead say "That's just how the game FAILS TO work"?

[@BiffaPlaysCitiesSkylines]

Not if that is how the AI was programmed. There is some imperfectness to the driving in the game which is pretty realistic

[@macaidwin]

I really love this junction testing by you, Biffa

[@braderwin6093]

Totally unrelated, but Biffa have you tried to use Extended_Road_Upgrades to control zoning? Absent a zoning tool, this seems to work much more reliably for me than placing paths. You can convert one side of a road to quay/retaining wall to prevent zoning. After you do the zoning you want and the buildings spawn in, if you remove the quay/wall then almost all of the time it stays as you want. Only occasionally do I have random zones break this way, where it was constant with the path method.

[@BiffaPlaysCitiesSkylines]

I have but awaiting an update to fix a bug 👍

[@Antti29]

There was really no reason to go for the 3+3 split at the end. If you'd stuck to the 5-lane roads, you'd have had the left slip lane, two going straight and two going right. Note that when the slip lanes merged, you didn't have the fourth lane for it. With the 1+2+2 setup, this wouldn't be an issue. I'd love to see how this setup performs! It would be so much simpler to build.

[@isaiahchamberlain]

i love when you do this stuff

[@thesunnynationg]

32:30 to equal your lane mathematics you needed to delete a lane on every road that connects to the junction bc you added the slip lanes to every side. 👍👍👍

[@amaangigani9372]

I'd love to see you explore Overpasses

[@israkhk]

Just do one left, two straight and two right... Advance split push and always left green... So, whenever there's green they dont interfere with traffic comming towards left.. ⬅️ ⬆️ ⬆️ ➡️ ➡️

[@LeverActionLarry]

The problem is, everyone is driving on the wrong sides of the road!! 😉 Cheers ☕ from the States.

[@mikeh6109]

This should be in the Vanilla game as an intersection. Call it "The Biffasection."

[@faustinpippin9208]

I just build a compact stacked intrchange in cs1 with "vanilla overpass" but i had to "ban" turning left (to avoid building the left turn ramps) in a grid pattern city it wasn't a problem

[@WolfTheTrueKing]

To everyone complaining about the AI art: have you considered that it makes 0 difference whether Biffa uses it or not? The AI image issue is a legal issue not an user issue. Please stop moralizing people as if its their fault the tool was created the way it was

[@user-wq9mw2xz3j]

Also, if said image is modified enough, it ceases to be borrowed images anyway. Picasso created his own Meninas basing it in Velázquez work and nobody accuses him of stealing.

[@hephaestion12]

I think when you were doing your lane managment you should have one lane right, one lane right and straight on, one lane straight on only, and one dedicated left. I think you see more queuong to go right because you have always green for left turns on? ❤

[@jonathanmarsh8119]

Instead of a single point interchange this looks like a nono-point interchange. If you used bridge and tunnels for the two straights, then the traffic lights would only need to deal with the right turns in the intersection.

[@WildcatRene]

As long as the devs dont fix the traffic, like where cars decide to change lane just before the stoplights, or parked cars want to cross the road like headleass chickens. The traffic will always caus problems. Waiting for someone to develop a mod that can remove all traffic accidents!

[@TinyEle]

Thats literally what drivers do in real life though...

[@complynx]

"Not a massive interchange", and the footprint of this junktion is already bigger than some no-light interchanges out there.

[@lowlandsgamer]

I watched as that intersection grew more and more complex. Did you know there's a solution for all those intersection problems? It's called a cloverleaf interchange. 😀

[@BiffaPlaysCitiesSkylines]

😬

[@timcollins340]

OK, I have to ask. The first half of the video made some sense, but after that... not so much. Did you have a day where you couldn't think of anything else to do?! 😅

[@A.Martin]

The protected right lights are fine, you just might need to have more right turn lanes. And less other lanes.

[@Zergonn]

A tool/mod for a combo roundabout/traffic lights would be great; setting timers, giving priority, that could solve a lot of traffic issues in the game

[@marksman1416]

I know traffic lights are better than roundabouts in the game but I would like to see how the game handles the magic roundabout.

[@denisslesinger7956]

You could maybe try the Swinden magic roundabout

[@zeroibis]

Would be great to see this rehashed with the impacts caused by trams! The effect of trams on intersections on the game results in some pretty funky stuff sometimes especially if you have a tram track that is not part of a road cross an intersection. I have seen some crazy light cycles caused by a 4 way intersection that had a tram on road and an off road tram. (ie a road with tram a road without tram and a tram line crossing the intersection.

[@adamt195]

You had the option at 32:00 to actually downgrade to 2 lanes straight, but give the left turns a dedicated lane to be RECIEVED on. 5-1 left turn = 4. Split 2 straight and 2 right.

[@unkl115]

Biffa... could there be underpasses and overpasses for the straight ahead. Might mean you only need 2 lanes going straight, and then only 2 right turn lanes are necessary because the lights would have no straight ahead traffic bothering them. I hope I'm explaining myself properly.

[@ozreshef5182]

It's hard to solve traffic when cars changing lanes everywhere, right next to the junction. It's must be like in CS1 that cars changing lanes at nodes.

[@jonblair5470]

In the vanilla set up, should be 5 on one side and 4 on the other not 3. The reason the right hand turn backs up is because it’s 2 lanes and the opposite road has 2 lefts, so 4 lanes of traffic going into 3 in the middle of the intersection

[@jacobtraupman6478]

Smaller round snouts closer seem worked better then bigger ones for me

Thanks! :-)

[@doctoronboard7542]

Hey Biffa, your roadtific testing is interesting. I would like you to test whether overpass/underpass would work well in CS2. So, the straight on traffic should use the overpass/underpass while the turning traffic should use normal junction. Looking forward to seeing the result.

[@vfridman94002]

This is great video and excellent research. However I tried to replicate your final design with three 3-lanes roads and the game would not recognize it as single intersection so I can't add and control the lights as required. Maybe you have to create the intersection at first using some other way, I'm not sure.

[@Jbear_Minecraft]

What if you make those each 5 lanes? Then what if you have stacked roads. How much can you really increase this?

[@bayani3]

For vanilla, could you do underground or bridge right turn slip lanes, removes the overlap turning lights. Then you only have straight lane with lights no overlap turns. Maybe even only have to do right slip lane on opposite directions so there is no overlap. 🤔🤔🤔

[@Jarvichi]

At 42:00 biffa says you can’t control the lanes in vanilla… on the junction at that time, could you use the “no left turn”, “no right turn” and “no straight on” built in signs to do it?

[@Jarvichi]

42:59 ok, you did!

[@smoore6461]

I think to run the real test maybe building things like housing, industrial and comervial districts would make the test more accurate but more time consuming as well. Sorry to say but i feel the devs dropped the ball HARD with the traffic AI since they had years of knowing TMPE was so essential in the game that npt adding some functionality like that from the start was a pretty big oversight. I had no issue with the optimization so many got upset about. Its underdtandable that they could not optimize for EVERY comfiuration or PC spec but knowing TMPE was so essential in CS1 they should have made it from the start. Just my opinion i know there are some people who feel that any suggestion the game is not perfect is a mortal sin, i would say ita very stable, it makes total sense thry could not plan for every pc spec and hardware but the traffic AI and no basic traffic conteol functionality from the start was a missed oppertunity.

[@finalFlickVideos]

"3,1 that could be 4, and then 4, 3, 7 we only got 5 lanes anyway"

[@norneaernourn8240]

It still baffles me that TMPE and node controller isn't part of the vanilla game. CS:1 becomes a nightmare of traffic micromanagement beyond a certain population if not for TMPE and node controller. At the very least, lane management should've been a base feature in CS:2.

[@SifuSkip]

I wonder if you can space each of the lanes out in such a way that you can have dedicated right-hand overpasses for each direction of traffic. There was that mod in CS1 that did small intersection overpasses, but it was hella awkward

[@ffximasterroshi]

I want to see you test if using the traffic light mod's lane direction tool on an intersection before changing it to a roundabout allows the direction selection to carry over to the roundabout, and if so, does it allow the roundabout to run more efficiently

[@ryanmoore8492]

Brilliant!

[@Arahknid]

Might be interesting to design a city for this sort of testing. 4 quarters of the city, 2 residential opposite each other with a industrial off one direction and a commercial out the other. Could use sports stadiums or colleges to help direct the heaviest flow to turn one direction or the other? Just vomiting out a possible thought was all.

[@zeroibis]

Maybe, I have seen cars get off a highway to get back on and doing a U turn to make it possible; some of the path finding in the game can get pretty wonky.

Not enough room for a great big interchange? What do you call that?! KEKW

Are you able to properly utilise a Park and Ride system? Free car parks and free buses from the outskirts of towns/cities to relieve traffic? I don't have the game myself but maybe the cim logic would choose this option rather than having to build mega crossroad junctions 😆

[@BiffaPlaysCitiesSkylines]

Yep 👍

@Biffaplaycitiesskylines really Miss timed traffic lights. LOL. Love your videos. How do i get the traffic light enhancement. ? Also question not this video related. I'm having Air pollution issue going on. I had a massive build up off it where i get half the map complaining. Now i wiped out everything that was red from air pollution and let it run . But the pollution doesn't go away. I've let it run for a few hours and regardless it won't go away and its a serious problem. I heard there is a bug with Air pollution. I heard its certain maps. Which i'm using Barrier island map.

The polution is even coming in in areas that i haven't developed yet. and has taken over half my map

There are 6 and 7 lane one way roads in large roads not highways but I’m not sure if that works

[@BiffaPlaysCitiesSkylines]

I will take a look at those next time :-)

44:30 I mean you would not see a layout like this in the middle of a city anyways xD at least not in a European one

[@aydendejong451]

I wouldn’t ever risk my life on any of these intersections. they look complicated to the level of magic roundabouts.

[@BiffaPlaysCitiesSkylines]

I've seen worse 😅

Try vanilla with north-to-west and south-to-east flyovers and north-to-east and south-to-west tunnels
