Making Traffic Use ALL LANES in Cities Skylines - Understanding the Traffic System

[@tinuviel874]

Good point about the road speed. Actually, I've often found reducing road speed limits very useful for correcting traffic problems. For example, if you've got two similar route options, but one is ever so slightly shorter, you can get huge backups on one while the other is empty. Put in a slower road in place of the one with backups, and you may find the traffic distributes itself more evenly between the two. Putting in bigger, faster roads just encourages more traffic to go that way.

[@YUMBL]

Great idea! I should have also mentioned the “old town” policy but totally forgot

[@BeachLookingGuy]

great point. i started using slower speeds to help keep stuff from piling up, especially on roundabouts. if i want cars to take back roads i use slow speeds on back roads and higher speeds on highways to encourage specific routes from certain parts of the city.

[@Seriously_Unserious]

With TMPE, you can also achieve the same thing without replacing roads by simply reducing the speed limit from the default on the congested road, or give the other, unused road a higher then normal speed limit, either of those can encourage traffic to use an alternate route but still leave the route available to the traffic where the alternate would make no sense for them to use.

[@Betha783]

Managing traffic is one of the things that I really enjoy about C:S. Also vehicular and pedestrian traffic gives the city so much life, and seeing them all go their way with proper road hierarchy and connectivity is bliss :) You explained it well!

[@royvandermarel3953]

The fun thing about this game is you have to plan ahead. Like, really far ahead. Think about where your traffic will flow to and from and build a road structure to fulfill this demand. But doing so, especially in vanilla, is hard, as you don't get all the road options from the get go. And it is hard to turn local roads into collectors without destroying all that's built alongside it. Planning ahead for 3- or 4-lane intersections make this even harder! Dedicated or combined lanes? Which direction demands doubling up on lanes? Could you achieve higher usage by growing in a certain direction? Man, I love this game.

[@YUMBL]

Its one of the deepest games for how simple it is

[@smoken81]

Hey YUMBL, console player here. It’s been my experience that cims will choose the faster road (within reason) over the shortest distance. Example: a large roundabout with a highway speed overpass will make the frustrating u-turn across traffic instead of exiting onto the purpose-built roundabout under the oncoming highway. Being limited to DLC roads and no traffic manager (to stop turns across oncoming traffic) makes for convoluted solutions.

[@YUMBL]

Correct!

[@khall187]

New player here on console and I'm just getting to 40k cims and I gotta say the traffic is absolutely horrible. I have fairly well designed city structure and still have cims going the super long way instead of the direct highway path... They'll go all the way around the city loop when they could just go right and merge for a quick trip. Drives me nuts!

[@saschab.5154]

Thanks for pointing this out. CS is actually super realistic. There's a reason LA is having constant traffic jams and some European cities can deal with it better. Making a better city makes traffic less of a problem.

[@deejeemadrox1866]

Srry, CS is absolutely not realistic. We often know our roads. When there are two lanes going to the highway and only the last 300mtr is one lane and the other 2 miles are two way, the cars take the left lane and the slower traffic the right lane, up to that point it gets one way. CS does not act like that. It draws a line from point a to point b and pick just one lane to draw and follow. Thats why you get that superlong one lane filled roads. IOW; we all are looking to "" cheat" CS to overcome the AI's handicap.

[@worlwr2]

​@@deejeemadrox1866 well Sascha is correct because they're likely referring far more to agents considering speed limits as part of its path selection, but yes you're correct generally but not quite. You're referring to something different, a dynamic / real time lane selection. C:S actually DOES have a real time lane selection system but it is limited only to emergency agents (and not the civilian agents) to balance performance and realism. Notice emergency vehicles dynamically change lanes to avoid occupied lanes as they're responding to an emergency call. This is on vanilla. As yumbl mentioned, normal civilian agents don't 'see' each other. Tbf from a certain perspective, that's true to life, it's common for travellers to not really care about one another and take a 'me first' selfish / toxic / hostile attitude and refuse to move or takes hostile action towards you. At least very true in cities and / or obnoxiously car dependent sht holes. Anyway C:S has a bit more depth than even the video depicts.

[@failtolawl]

this is a massive fucking cope. LA traffic comes from traffic snakes and HIGH VOLUME. LA traffic exists on ALL lanes when it does. It does not come from a bunch of AI following in one lane just to go to the empty lane at the very time they need to turn off. This is dumb.

[@Azerkeux]

I love how you are explaining this from the perspective of game mechanics, I've had a hard time getting cims to properly utilize asymmetrical roads and now I see why

[@YUMBL]

[@williamhuang8309]

Generally, I try to avoid using ridiculously wide roads, as they ruin walkability. I usually don't go much higher than a 4-lane road except at major intersections, where I might put a 6 or 8 lane road depending on how busy it is.

[@YUMBL]

I think the moment a light or roundabout is added the width of the road no longer matters to walkability in the game.

[@YUMBL]

I’m glad to hear it! Thanks for watching :)

[@D.Trinchuk]

1. If I'm not mistaken, cars do consider possible jams. To be more specific, they factor average speed on the road rather than maximum, which is determined by traffic jams you have on the road. But there's one problem with that. To factor the traffic jams you actually need to have the jams, and only after a backup is stacked and average speed on the road is recalculated, newly spawn vehicle will consider taking another road. So, building a detour cannot clear your main road off the traffic, only reduce it, because cars will take a detour only if there's a jam on the main road (works IRL as well). And there's a delay in reaction, cars chose their way from the very beginning. 2. About not using other lanes. I used to have that problem before, but somehow I overcome it. At first, use the "dynamic lane selection" option in TMPE. I'm not sure if it helps or if it's a placebo, but I use it anyway. Secondly, you can manipulate with lane connector. How's that? Well, if you have cars stacked in one lane, the chances are they're going the same way. Look that way, as you showed in video, and propose an alternative with lane connector. For example, in your case, you can take your intersection and merge two onward lines into one they are going to. But that won't be enough. Then you go to the previous intersection on their way and split the lane they came from into two lanes you want to use (in your case it’s not the intersection, but the node, where the road switches it's asymmetry). Now that should work, because you literally gave the cars two equal options that they will choose randomly.

[@YUMBL]

The cars only know the speed limits of a given path. Not the current speed of traffic. They dont path based on one another at all.

[@hssein7773]

Using the traffic policies such as “encourage biking, heavy traffic ban etc” could also work. Great work with the traffic tips, you do deserve more subs

[@YUMBL]

Thanks a lot! Policies can be important too. I wanted to keep things general and non dlc specific

[@Seriously_Unserious]

Very good advice, all of it is very true and applying road hierarchy has helped my cities get much better traffic flow. One thing I've also found helps, for when you still get that 1/3 lanes used the other 2 ignored scenario is to change the TMPE AI system to have it use improved AI, as that can induce vehicles to change lanes based on traffic at higher settings, and thus get lane condensation back-ups to free themselves up simply by allowing the vehicles to spread out and use all the lanes. Dedicated turning lanes at intersections also helps, as vehicles will tend to bunch up on all purpose lanes even when they don't have to and get in each other's way as they all choose the lane that can go left, or straight as that satisfies the needs of all drivers who will be turning left at some point. Same goes for those multi-purpose straight+right lanes. By making lanes that are left turn only, right turn only and straight only, you force the vehicles to spread out and use more lanes, since the middle lane has to turn left, anyone going straight can't use that lane and has to use another lane until they're ready to turn left. Those turning left, have to use the middle lane as they can't turn left from any other lane, and so on. That's a basic and essential part of lane management and though it was shown visually, it was not explained verbally, how and why those dedicated turning and straight lanes were used and how to include them for those who don't know how and why to set that up yet.

[@marcusjohansson668]

I have gotten the explanation of traffic (ALL traffic, pedestrian, bike, cars, public transport etc.) that they calculate the pathing by adding a penalty points to the routes. I don't know the exact number added by each entity but it goes like: Bigger roads has less penalty points than smaller roads. Faster roads adds less penalty points than slow. Each intersection/lanechange adds penalty points. Using a car adds more penalty points than public or walking, transferring between public transports adds a tiny penalty (still lower than cars) etc etc. So f ex if you have an intersection you can use increase the speed in one of the lanes and that lane will add less penalty points to the vehicles and they will prefer that road (I think each segment of road adds penalty points, the faster the road, fewer points, the bigger the road, fewer points). So the thinking of traffic as agents is absolutely correct, and each agent calculates the route (when they start) and chooses the route with the LEAST penalty points. You can further modify this by using TM:PE (to change individual speeds in lanes it's needed anyway, as for my example above) and instruct the vehicles to also get penalty points if an intersection is slow with a lot of waiting times. Special lane rules (I think its called) f ex makes it so they never change more than one lane at a time (you have probably seen traffic come to a complete stop on a highway because vehicles comes to a complete stop while changing 2 lanes over, that setting removes that). Otherwise, as usual, a well thought out video from JUMBLAcorp (as me as a swede pronounces it xD)

Can you actually change the speed of lanes individually!? How?

[@azuarc]

Here's the problem I have, which this video did not address: I have a long arterial. It has a major point of entry. Let's say a highway. And after that point, there are maybe 10 or 12 other arterials and collectors intersecting it. Maybe you can make a left turn at all of them.And since this arterial is toward one side of the city, most of its traffic will EVENTUALLY be making a left. So what happens? EVERY GOD DAMN DRIVER GETS IN THE LEFT LANE. It doesn't matter if they're taking exit 1, exit 10, or exit 999. They want to be in the left lane and they DO NOT CARE about anything else. The fact that your arterial is a 6-lane one-way road, and they have literally four middle lanes to choose from is irrelevant. The only deviation from this is if the roads being turned onto are more than one lane. Then you have multiple left-turn lanes, and thus all but the last cannot go straight. For the sake of argument, let's say you have lights with two-lane-each-way traffic. So the traffic not turning there doesn't get into lane #6...it gets into lane #5, which is also a left-turn lane, but has the potential to go straight. And you would think, okay, well, if the traffic turning there has a lane to exit from, at least *THAT* traffic isn't going to be in the column of death, right? Wrong. Because any cars getting off at this point then ask, "Which lane do I want to be on in the new road?" And if the answer is the right lane, then they say F U to the left-most lane because the second-to-last lane corresponds to the right lane on their new road. It doesn't seem to matter what kind of outflow you have from these roads. Any sort of impedance whatsoever will result in this major, major traffic snarl. If you're lucky, and plan well, it often clears before becoming a 10-mile one-lane traffic jam. But this is a circumstance that, really, either shouldn't happen or that there should be some sort of recourse for beyond downloading mods like TM:PE. Is there?

[@BeachLookingGuy]

yumbl always bringing great topics to the table.. this idea hit very close to home as the traffic system is my absolute favorite part of these games. it's a giant puzzle always evolving and growing; for some reason i love to watch it simulate.. the tools mods and vanilla systems really creates a unique play style that not many * if any * other game can provide. But i gotta say simple stuff like cars stacking one lane while another is empty really breaks the immersion. the traffic system in this game paired with mods makes for a diverse and complex mechanic alone; ive spent hours tweaking lanes, speed and restrictions trying to make things flow at a decent rate. sometimes i think i spend too much effort on this games traffic rather than something more productive hahah.

I am surprised you did not mention lane math here. This can help reduce single lane backups. Since vehicles on a "through" path pick the leftmost lane, having fewer lanes, as well as putting exits before entrances, causes fewer weird merges.

[@johnterpack3940]

You really should have talked about lane mathematics. That has a major impact on traffic. A bit trickier is paying attention to node spacing. Putting exit ramps too close to another node can cause problems with wanton lane switching. Pretty much always best to avoid using short segments when possible.

[@YUMBL]

I dont really think in terms of “lane math”. I may add a dedicated turn lane where necessary, but thats all. Same for highway. Adding before an exit is what happens on real highways.

[@HerrRoehrich]

I personally expected a mention of TM:PE's lane connector system. I use it all the time to direct traffic flow on multi-lane roads, e.g. if I know that there's a highly-frequented left turn coming up, I force all traffic wishing to go straight or right to use the right lane by preventing lane switching several nodes ahead of the intersection. It works really well.

Living in Southern California, specifically Orange County, has messed me up a bit with trying to figure out road layouts. You can almost take the speed limits you mentioned and bump them up one level so the highway almost a becomes glorified arterial in some ways. 😅 Hell, what Google Maps insists on calling "Highway 39" is more commonly known as "Beach Blvd," and Imperial Highway and Pacific Coast Highway (90 and 1, respectively) are generally regarded as arterials. I was rather surprised when Google Maps told me to take an *on*-ramp to Jamboree *Road*, although that segment of Jamboree Rd. admittedly is more highway-like than road-like. It all comes down to jurisdiction and who is responsible for maintenance. The part of Imperial Highway that the city of Yorba Linda assumed responsibility for lost its highway designation and was subsequently redesignated a Parkway.

[@eran0004]

One thing to add, about road hierarchy not always working, is that you can adapt the roads according to how they are used. If a ton of traffic is using a local road because it’s much shorter than the collector/arterial option, then perhaps that local road should be upgraded to a collector. The point is that you can’t always dictate what the traffic should do, sometimes you need to adapt to what the traffic is doing.

Hi I want to put a disclaimer that a highway is also considered an arterial.

Your knowledge and tips are remarkable but you haven't truly provided a real suggestion on how to make traffic use all lanes, instead you just gave some valuable tips on how to avoid the need. Traffic coming from 1 lane road to, let's say, 6 lanes road won't ever get distributed. They will pick a lane based on the exit (the closest possible) and sticky to that. The only option you have is to force traffic to go straight and keep traffic from different merged sources on separated lanes but at some point you would have to allow it to change lanes so they can exit on wherever they want. I'd like to see some more tips on how to fine tune lane usage as I have never seen a 6 lanes road which wasn't a waste.

If a cim will choose non-vehicular transit given the opportunity, then to what effect does the “free public transit” policy have on their choice? This policy seems to imply it’s not a total given that people will choose their leggos to move around.

[@lukasmax6984]

I love traffic xD

[@YUMBL]

Same ;)

[@plaxci]

Same! I personally feel like it adds a touch of realism and problem solving here and there. :D

[@PanFaworek]

Awesome video explaining a lot of important stuff, but still there is a problem with the traffic mechanic. Citizens very often do dumb stuff which sometimes contradicts the theory of "choosing the shortest/fastest route". Let's say There are 2 lanes for turning left into 2 lanes after the intersection and then they split into left and right turn. A wise thing to do would be to choose the left lane at the first intersection if you want to turn left at the second one. But in my city I observe a complete madness, where the guy that was on the left lane, after the first intersection changes the lane to go right, and the other one that was on the right lane, changes to the left. And they stop in the middle of the road and the intersection is stuck. There is no game mechanic or a mod that allows you to fight that if you want to make a free-flowing right turn from the opposing side, because if you prevent them from changing lanes after the first intersection, cars from the opposing side turning right won't be able to turn left at the second intersection. It doesn't make any sense.

[@zuthalsoraniz6764]

Couldn't you allow the cars from the free-flowing right turn lane to change lanes after the first intersection, but not the ones from the other left turn lane?

Nice video! Keep up the good work!

Both these links are the same. It would be nice to have the actual Road Hierarchy link. Thanks for your videos! Road Hierarchy Explained: kzbin.info/www/bejne/fqGvc5SvfrtorrM City Starts Explained: kzbin.info/www/bejne/fqGvc5SvfrtorrM

At 3:56 what road texture pack is that?

[@YUMBL]

I use “USRP” highways

[@YodaWasSith]

11:00 "Please don't say it's the intersection's fault," and "I know what you're thinking, a roundabout would work here." It is the intersection's fault. I understand you induced the traffic there by diverting a section of highway through the back roads, but say you have a situation where residents and truck traffic are merging together at a 4-way intersection and all trying to cross one another. The solution isn't necessarily a 4-way intersection, it's likely not a roundabout either as there's simply not sufficient traffic from the East-West collector. The solution to this scenario would be a simple overpass, you have through-traffic that needs to get to the highway and you have traffic that needs to join as well as cross that, but at a much smaller volume than that of the through-traffic. So give it a direct route and force the smaller volume to merge with it. Don't smack a roundabout in and call it good, think for a second about the types of traffic you're moving and how it needs to move. If it's just headed straight for the highway, don't impede it in any way if possible. I forgot to also mention, something you accidentally did there at 11:00 was demonstrate how important it is to plan your road network around what you plan on zoning in that area. You've clearly dictated this area is residential and thus light residential and some commercial traffic is expected at the 4-way, not the full industrial and commercial traffic of 4 different districts (I assume) trying to get through the intersection and hogging 1 lane for miles and miles to do so.

great intro. too bad you said that you won't do it again ^^

Hierarchy has an "R" sound in it.

I so do not care 🤣

[@micklogan5489]

Hi beginner here. At 2:07 there’s a pedestrian crossing in the middle of a road nowhere near an intersection. How is that done?

[@YUMBL]

I think I used the mod “node controller”. If you’re not playing on PC you can use a different road type. The walk will happen at the transition imgur.com/a/add-crosswalks-middle-of-roads-SiYJl

[@KubicaMr]

Mostly you are right in theory of road planning etc. But in this particular case you really can`t make traffic use all lanes like in IRL, you just say you got traffic jam, it`s your fault (which mostly is) and build bike lane or make public transport and rebuild roads so you fit in a way cars move in CS. Don`t know why but the traffic AI behave like typical american road user (and far as my typical american driver stereotype is right) THEY DONT LIKE TO CHANGE LANES and ones who change lanes looks like maniac. Like in Europe there is rule that if you arent overtaking or turning left in a moment you must use far right lane so you dont block faster cars so when other vehicle is faster he can overtake you easly and also cars can use all lanes rather then just sit at 1 lane and wait 3-4 light cycles to pass junction.. But in america even on highway you pick any lane and stay on it until your destination. And this game has the same problem, changing lanes is undesirable. Even if you calculate route at spawn once, rather than calculating route constantly game could take into consideration choosing other lane which is empty and follows the same direction and then after crossing junction merge into desirable lane, and we know it can be done because in your example there are like 4 nodes which allow vehicles to change lane. So this game has flaws like no considering other lanes which go in the same direction and then change lane before next juncition and changing lanes is wrong because nodes allow only tight lane changes and when you go 20km/h its fine, but on highway or faster roads cars slow down and make tight lane change to fit inside node when changing lanes, insted just make process smoother and faster but exceeding nodes boundaries.

[@YUMBL]

I’m not sure where you heard that Americans don’t like to change lanes but it’s bizarre and false.

[@mts5201]

I love his videos so much... such great attention to detail and the explanation is on point. And god I love his arterial road asset... i looked through everything in his collection and I failed to locate it. But it really is good road and the info given here is top notch for game and reality. Thank you 🙏🏼

What are these black roads you use? I tried searching through your collections but I can't seem to find it. Thanks!

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

[@xOzymandias]

I need help, I can't find my assets in game. Tried find it. Nothing. I subbed to some commercial stores, the mixed use buildings and they're not appearing in game

[@YUMBL]

Make sure they appear in the “content manager” to make sure theyre really subbed, then look in find it under “growable/rico”

[@xOzymandias]

@@YUMBL yeah they're in content manager. So they appeared after I first subbed, I "add to local" modified workers/homes on realistic pop. Saved left game, when I tried to play again I can't find them at all 😕

Look under the ploppable rico buildings maybe. Icon in the UI

I’m glad to hear it! This was a fun one :)

[@buckrodgers1162]

It's just too bad the 'Road hierarchy' don't work in Transport Fever 2. Because no matter what, most cars use only 1 lane, and stoplights do nothing more than cause major backups.

[@silverczaja]

ye, but if you work with a flawed system, with sims picking roads ahead of time, instead of adjusting, there is no way you can ever win fix the base system paradox

[@YUMBL]

Give them another route. Thats your job. Thats the solution.

[@nickfunkmaster]

My newbie solution has been to eliminate the traffic light, and let them all go at once! haha Is there a big downside to doing that though?

[@YUMBL]

A good traffic light is more satisfying and realistic :)

[@wulphstein]

I like characters from the 1950's.

[@jonm3024]

Ok... but so, if everyone is going to the highway, the only benefit to using higher capacity roads is that they go a little faster, right? Cause they are still gonna only use the one lane.... Would you get higher throughput using 2 little roads instead of one big one? That way you force the traffic into 2 lanes, and use similar space... (2x25=50) > (1x40=40) Or even better, like 3 onramps... (3x80=240)

[@YUMBL]

No. The only reason the traffic was all going to the highway was because I deleted a section of the highway forcing all the traffic through the city. The point overall was that traffic picks lanes based on destination. Design your city so the cars are NOT all going to the same place.

[@herbie_the_hillbillie_goat]

How did you set the default highway speed to 70? Mine is 65 by default.

[@YUMBL]

The USRP highways come that way

[@dominikvincentlatsch3516]
