Aa area's initial branch of a highway is what I always struggle with. So much traffic still has to go through that area. How do you deal with this without placing new off-ramps every five metres?

drat, roads are becoming the bane of my existence. Am I correct that the general pattern I want to follow is 4 or 6-lane spines feeding into lots of 2 lane grid communities, with as many one-way streets as possible to avoid weirdness like trucks and industrial vehicles pathing through residential roads and getting stuck?

Close, but not quite.

You don't want “lots”. You want a freeway, which feeds a handful of 6-lane spines, each of which feeds a handful of 4-lane, each of which feed a handful of 2-lane. If you start adding too many sub-branches, the road clogs up from the traffic volume. If you add branches too close together, the road clogs up from the constant red lights at crossings. If you put in shortcuts that let traffic go from A to B without using the main thoroughfares, everyone will love the shortcut and the road will clog up.

You might spot a reoccurring theme here. :D

Amateur :words:

Roundabouts are a common solution to the clogging up due to road crossings, and they help up to a point. However, even a roundabout is a crossing that vehicles have to slow down for and/or wait for passing traffic to clear. You can solve this to some extent by having proper feeds into the roundabout that reduce the angle of the turn, but you then come across the issue of how C:S assigns turning lanes and how the AI picks what lane to drive it — traffic will still interfere and will still occasionally make very sharp turns that (wait for it) clog the road up. Mods like TrafficManager and Traffic++ can help with these issues by letting you manually assign turning lanes and proper paths through the roundabout, and generally make the AI drive better. Either way, the main point here is that you want to build big. Leave lots of room for traffic to settle between high-traffic crossings; leave lots of room to later let you upgrade with better (read: larger) roundabouts and feeder lanes.

If you want to give people (as opposed to traffic) short-cuts to across these large areas, say to go from a residential area to a commercial one for shopping and/or work, pedestrian/bike paths are very useful. They also let you split up the zone squares in a way that's perhaps more to you liking and creates a bit of natural separation. You could conceivably make use of one-way roads to shape traffic between these areas, but as mentioned, any such shortcut will either be unnecessary or become a favourite and see heavy traffic that you might not want to see. Policies such as Heavy Traffic Ban and Old Town helps a lot more in that case, but even then, your shortcuts will still be popular with vehicles that are allowed. Fire trucks, garbage trucks, hearses and ambulances excel at clogging up these kinds of roads and there's no way to stop them. Well, aside from not building the road…

Personally, I suck too much at building “live” so I make extensive use of the asset editor to make prefab ploppable crossings for highway crossings, offramps, and regional and local roads, but even these will not stand up to heavy use so even then, minding what leads to where is still the best way of ensuring that no stampedes occur in these areas.

For instance, look at the central underpass roundabout in this:


It used to lead to both the industrial zones to the left and the residential and commercial zones to the right, and even though it was early low-density stuff, by 30k population, the whole centre area was solid red from traffic jams. Cutting the road between the offramp and the residential area cleared it up in no-time, and while it's working at the moment, I probably have to rebuild it to create a more direct connection to the on/off ramps. And replacing that T-intersection that connects the industry with the commercial zones on the other side of the freeway will soon become an issue too…

If you mean initially as in the early game, then there's very little to do — just build it with future restructuring and expansion in mind (i.e. lots of space). Later on, it's mainly a matter of ensuring that the connection only really leads to one thing so that it's not being used as a shortcut to get to somewhere else. Depending on what kind of area it is, in my experience it also rather becomes an issue of having enough on-ramps, but luckily, highways aren't as easily disrupted by those as local roads are.

One thing you want to be careful of, though, is cargo. Make sure your industrial areas have straight shots to the city exits and harbours. Run dedicated ground-level trains from your industrial zones to the cargo harbours.

At some point adding more intersections is just going to cause more traffic.





My airport doesn't generate much traffic oddly. I have a bus route dedicated to ferrying them into the city.
Neither does my passenger harbor, just because it's in the heart of the city. Ignore the crazy population numbers too for such a small place. I have a mod that increases numbers but doesn't seem to change the traffic numbers at all. I had the same problems before the mod.

My highway roundabouts aren't great, but they've actually not been clogged since adding the two bridges into the city. The two bridges have highway connections, but they're pretty far away so not all traffic goes through it. Freight usually goes through the highway despite the beauty shot having a freight train right there. I have zero industry inside the city.

My suburbs have virtually no high density too. Only one side has it a little bad, but from what I've seen most of the traffic is highway and not the suburbs. That main road that cuts through everything is what usually clogs up though. From the sounds of it, I don't have it leafy enough in design. So I'm starting to see where I could fix things.

Just for fun, a beauty shot of the city.


One thing I would suggest to folks that I've learned which will cut down on car traffic is mixing the zoning up. The city will look more realistic too I feel. So let's say you usually do this:
=========
RRRRRRRR
RRRRRRRR
=========
OOOOOOO
CCCCCCC
=========

R = Residential, O = Office, C = Commercial, ='s are roads

Do this, and people will walk a lot more.
==========
RCRORROC
OORORCCO
==========

So long as you never zone high density commercial without a buffer of light and offices, residents won't complain about the noise.
You can also get really interesting blocks if you break up the rows with 3x3s and 1x1s in like a 4x16 area or something like that.

My immediate impression is that your two main roads through the city are too close together. You can trace every tailback to two intersections: one down and to the left of the “M” in Marakest City, half-covered by an abandoned-building icon, and another one further down to the left just past the bend in the road and the not-yet-critical dead guy (also covered by an abandoned building).

It looks like the short sections of road that connect the two main thoroughfares at these points are filled up with traffic, presumably waiting for a red light, and that anyone trying to pass those intersection is being interrupted by that crossing traffic. This, in turn, creates queues that block other intersections further down the road(s). I can't quite make it out, but I'm guessing that these are two one-way 2-lane roads acting as your main strip? With that kind of construction, you almost have to make use of some kind of non-blocking crossing — either a sizeable roundabout or just nuking the traffic lights with a mod and hoping that your cims can navigate Parisian traffic. :D

By your description, it doesn't sound like it's a case of bad zoning — cargo trying to make its way between opposite corners — so you probably have to build your way out of it. If you use one of the many traffic query mods, you can poke the vehicles and try to figure out where they're coming from, where they're going, and why, and just build them a better route that doesn't take them straight through the city centre, but that's not as neat a solution.

Yeah, the strip is two one way 2-lane roads.

So more roundabouts instead of intersections along that strip, and it should help smooth things out. I can do that.
I kinda already have had "Parisian traffic" when testing different one way road configurations. Every time I forced traffic to go elsewhere and split up, I just moved the clogs around without fixing them. :cripes:

This helps, believe me. Despite using them to funnel traffic around the outskirts of the city, I never thought to put them inside the city. It just seems unnatural to me as an American.

Edit: Not sure it helps, but the main thoroughfares? It's trees and parking lots in the center. Not sure if that encourages people to walk more or not. But I have several giant parking structures too (I know they don't actually work like a real one, but they do have some spots). I've heard having parking encourages people to walk more.

I don't have any traffic mods. The only one that 'might' cause issues is this one.
https://steamcommunity.com/sharedfiles/filedetails/?id=426163185

Which just fiddles with the numbers without actually causing more traffic. And I can confirm prior to this that my traffic problems were the same. So it's achievable under a default game. The only thing that would be odd would be the higher number of residential I have in the city.

If you really want the save file though, I can do that. It's nothing special as a city. I'm purposely leaving out some uglier bits in pictures though.

I've found this to be a good solution. Extend the highways with 2 lane oneway roads some cells down, around 40 or so (no hard rule on this, I just eyeball it). Then cap them off with T-junction using a regular 2 lane road. Avoid bigger roads since traffic lights will make your life miserable at this stage. Make sure you have at lest 4 cells between the oneway roads, or the close by T-junctions cause the traffic to do this weird stop'n'go dance.


Res & Com side
......|.....
----->|.....
<-----|.....
......|.....
Industry side


The gap between the RC and I sides should be around 40ish cells. This leaves fair margin for the next step. When you get to the city size where highways become available, your traffic should still work kinda OK. Save up some money or take a loan and use the highways & ramps to build a proper service interchange. This design, or a variation of it, is usually what I use as it can handle quite a bit of traffic.



Trick here is that the industrial side is linked with a 6 lane one-way road, that ends into three branching 2 lane one-way roads. This "traffic trident" spreads out the incoming traffic very effectively and causes virtually no jams. Just don't zone any industry on the trident branches or the 6 lane segment! Industry has couple dedicated off-ramps back to the highway and out of the city, and couple direct road connections to the R&C side for goods traffic. This keeps trucks on the highway and industrial side.

This solution does not scale to arbitrary size, so it's a good idea to start planning additional industrial areas once your city is getting to the 30-40k range.

I'm visiting Dusseldorf today, which seems to be a very C:S-ish place. Looking at the harbour though, I'm thinking about the game's somewhat poor coast terraforming tools and how badly roads and buildings interract with water. You can sink tonnes of hours with workshop assets to achieve a similar effect, but it's all hacks, really. I remember a similar issue with SC4, where a realistic urban coastline would also require hours of work and dozens of little hacks. It'd be great if they'd address this one day in Cities: Skylines: Coastlines.

I suppose. I just don't like zoning along 6-lanes to begin with unless it's offices. At most, I use that space for services that provide happiness but that don't generate much in the way of traffic (subways, parks, the occasional unique building).

Maybe a highway where each direction has tons of on- and off-ramps on both sides of the road? That would give you a near-constant merging lane on each side and four lanes for passing through in the middle.
