➤Cities Skylines Industries:
In one of the most in-depth expansions in Cities: Skylines history, Industry becomes a larger and more meaningful part of the game with this expansion. Players can customize their industrial areas with supply chains for the four different resource types and unique factories. Well managed industry areas will level up and become more efficient. Aside from production chains, there is a new city service for handling mail and the cargo airport eases import and export of factory goods. There are FIVE new maps, new policies, new city services, new buildings (including resource extractors, manufacturers, warehouses and unique factories) and more.
Key Features:
MAKE IT HAPPEN
Follow your products from harvesting to processing, storage and production, then transport them to commercial zones or export to other cities.
CAPTAIN YOUR OWN INDUSTRIES
Define an area with the industry area tool and place highly specialized industrial buildings to build and manage the production chain from raw material extraction up to final end product. Industry Areas are divided into four types based on the natural resource they are processing: Farming, Forest, Ore and Oil. These areas can level up upon reaching productions goals and staffing requirements.
BUILD IT UP, BUTTERCUP
New industrial buildings include Extractors, Warehouse Facilities, Processing and Auxiliary Buildings, Industrial Props and Roads. Unique Factories, such as Food, Toy, Furniture, Car and Electronics produce luxury products, and require a large number of workers, water and electricity as well as input from your industries.
GO POSTAL
Boost your citizens’ well-being with mail delivery and collection services. Post sorting facilities handle mail between outside connections and the post offices, and new Post Van and Truck vehicles enable the carriage.

[@evanparker9282]

I started flipping out because in my city there’s this ONE FREAKING bus stop that is so close to the intersection that causes a massive backup in the intersection and people can get no where

[@MephistoDerPudel]

@@evanparker9282 Bus stops at intersections make a lot of sense though. While they may impede traffic flow, they allow easy acces to multiple roads by public transport travellers and also easy transfers between crossing bus routes. Slowing traffic down (not causing jams, but rather make people go slow and wait sometimes) is also a common theme in traffic engineering to reduce speed and therefor the risk of crashes and pollution. This includes having Bus stops on the road instead of bus bay (which also has other reasons like safety for people at the bus stop and a wider gap between bus and bus stop at bus bays). There are a lot of things at play in real cities, that aren't simulated in the game and while there's a lot of ways to improve things in real life, Biffas methods of fixing traffic in CS would fail horribly if used in real life. Especially thanks to a thing called induced demand: fixing traffic creates more traffic.

You know, mods are great and all, but seeing how to build roads wrong and how they ACTUALLY should be built is way more satisfying, even if you hate rebuilding the original roads

[@Vespuchian]

I agree, I'd like to see more videos where Biffa actually changes the road layout and/or builds new roads instead of just using Traffic Manager to jigger with lane access.

[@GusVardas]

This would be great however, it says a lot that so many rely on Traffic Manager to begin with. The game mechanics, AI and vanilla tools just aren't good enough in most cases to accomplish what should actually be happening. That's not to say the mod doesn't just make some things easier (because it truly does), but the game itself is just so horrible at traffic it's pretty much necessary.

[@thecreatorofthedark]

@@GusVardas you want bad traffic try sim city

[@Vespuchian]

@@GusVardas It's so easy to forget just how _old_ the basic programming for Skylines is. Even with patching, the base game is five years old now and was not designed with the sort of fidelity to real traffic patterns people expect these days. That said, the traffic simulation is _good enough_ as long as a creator lays their city out aware of its properties. I personally think a prospective Skylines 2 needs an overhaul of the water engine more than traffic.

[@GusVardas]

@@Vespuchian Oh for sure. I'm aware it's a 5 year old game. That's why the mods are so important and in some cases absolutely necessary. What issues do you have with water? I can without a doubt say that in all my time in Skylines I have never experienced issues with water. Or at least anything game breaking enough to require a mod to fix.

[@bryndenrivers1697]

[@ouzoloves]

What did you do Biffa? So many buildings disappeared between the before and after wipes. Did you solve traffic by reducing the population and thus the amount of cars/lorries on the roads?

[@yigitcanerdogan1596]

he disabled the realistic population mod because it was causing a lag; which is I think what caused the decreasing population. I don't think it made his job easier though, because the game can spawn a finite number of vehicles anyway and I think this city started and remained on the max level of vehicles spawned.

[@peronohaynada]

I would change the end of the highway. Instead of ending in a roundabout, let it continue (merge to 6 lane road) and have a roundabout in a different level

[@peronohaynada]

so I've been using the tips and tricks from the fix your city series. my population plateaued at 87,000~82,000 (used a mod to unlock ALL squares on the map, made use of all of them.) and had an average traffic percentage of 83% mostly due to ONE BRIDGE from the center island being used by everyone in spite of the other three being just as accessible. the people of New Atlantis are thriving and happy over all. thanks for doing these videos.

[@adamcetinkent]

Changing speeds on those bridges might help. The game calculates shortest path by time rather than distance, so if you do some speed nudges, they might choose different routes.

[@RN-du8wr]

I spent 8 hours working on the bridges and came to the time over distance conclusion somewhere at the end. but thanks for feeling so inclined as to put the tip out there, you confirmed what I was thinking. the bridge causing the issue is now set to 50 while the others remain at 80 and I'm considering revising parts of the infrastructure. thanks

[@abfruits]

Heh. I love when I find a 2-3 year old fixit video where there was an update (like the lane connectors here)... it is so fun to see the feature being born!

[@autolykos9822]

Nice demonstration on why classic DDIs don't work in Cities: Skylines. Timing the traffic lights properly is essential, but very hard to do. Luckily, you can get away with replacing the crossings in the middle with bridges and/or tunnels, and then they work even better. Just as efficient as a cloverleaf, with way smaller footprint. (But roundabouts are fine, too, I guess.)

[@youngbeard]

I have made those diverging diamond intersections work, but it takes a timed traffic light and a lot of weird fiddling with lane maths and you go there wiring. It's a PITA, but it's beautiful when it works.

[@sniper6823]

Biffa, I love watching your videos, even if im feeling like garbage watching any of your videos makes me feel better.

[@brickisland6353]

Good to see that you use the TF and tell Cims were they can change lane, it’s really effective on 3 or more lane highway when they start to switch more than one lane in one point, that really slows down traffic

[@seanm7445]

I don’t know why, but the background music around @4:39 gave me serious nostalgia pangs for Rayman Advanced (for Gameboy Advance). I’m not sure if it was the sounds of electronic celeste...

[@whatbrains]

I watch hours of these videos. They are so chill and educational, and make me feel like a civil engineer. Something I've noticed is that the cities never follow the basic principles in Biffa's videos. Their round abouts don't give way, their lane maths are non-existent. It's like they don't even watch the channel. I'd love to see episodes where the submitter has already tried those things and still has traffic. Then Biffa could solve the more fundamental road design issues, which to me is the fascinating puzzle that keeps me watching. Great channel!!

[@BiffaPlaysCitiesSkylines]

I have fixed up some cities where the viewer has already done pretty much all my tips. They were pretty hard to do! 😁

[@rahpower1]

This reminds me of a city I am working on. A main highway through road down the center. I have despawing turned off with proper junctions but the highway still has serious traffic backup because of lane switching. Ive updated the traffic AI with the traffic manager mod. seemed to help a bit but still annoying. The AI is not driving all the way across the road its the single lane switching that causes build up just because of how busy the highway is, a lot of outside traffic just passing through. Also have one of those crazy cross lane junctions that you switched to a round-about. Personally i just kept fiddling with it until it worked by setting the lanes at different heights to reduce cross traffic. I like verity when looking at the city from high above. Thanks for your videos Biffa they are inspiring.

[@Landrassa1]

That crazy cross lane intersection is known as the Diverging Diamond Intersection and it is a real thing. Unfortunately all the things that make it decent in real life are either not applicable in Cities(trucks being much more aware of other traffic for example) or would take forever and a degree to set up (the traffic lights need to be timed perfectly). So yeah, a roundabout setup with traffic manager simply works better in the game. In real life it would probably have a much higher incident rating than the DDI in traffic situations like these.

[@BackSeatJunkie]

Yeah, that junction at 15:30 was bugging the crap out of me from the very start of the video. That was a hot mess of "too much" when what was needed was a "less is more" approach.

For your two new elliptical roundabouts, I think you could have given them two lanes (instead of one) for leaving to the north/south (to the 3+3-lane non-highway roads), because that's where most traffic wanted to go. Now the inner lane is mostly empty.

[@pologolfpolott1096]

My biggest hints for this game are NOT to use highways. Connect straight to a roundabout once and that's it. Have main roads as arteries and place NOTHING on them. Put all services local to each neighbourhood. No buses. No trains. Garbage collection spread out. Metro everywhere.. Lots of paths..85% traffic flow on cities up to 100K is easily done.

[@Larwood.]

Yeah it can be made to work but you have to spend so much time controlling where the lanes are going, it's just not worth it imo.

[@dlwatib]

Those diverging diamond interchanges (DDI) have traffic lights in them. They need to be set up properly for the junction to work efficiently. The other thing you can do is replace the traffic lights with overpasses. This converts the interchange into a double crossover merging interchange (DCMI). en.wikipedia.org/wiki/Diverging_diamond_interchange

[@andreamenta127]

I can't say how much i like watch you fixing traffic, and i use some of your tips in my cities, but, to be honest, when you fix highway exits, there is a little thing you do, with lane "mathematics", usally you dedicate one lane to get in or out the highway and the other two lanes to get straight ahead, and the middle nodes set to go just straight, no switching lanes, so you make not possible to cars to exit in that specific point. I think with all the correction you do, those little mistakes are normal, too much mess around to deal with. Thanks for your videos, keep up with the good fixing!

If a DDI was terrible for traffic, the city I live in wouldn't be building one.

I build them in my cities all the time and they always work properly.

They built one in the city I live in as a sort of experiment a year or two ago and even during the busiest times of day there’s almost no traffic sitting at the lights. It’s incredible how well it works IRL in the right situations. I wouldn’t want to imagine it being a big roundabout instead...

You may need to change your Shift + Ctrl roundabout setups, as the version 11 auto-setups the lines on the lanes to keep motorists in that lane, so they can only switch in the roundabout junction. 1:54

[@jayzo]

With the network extensions, it's worth using Traffic Manager to ban everything but Buses and emergency vehicles (and maybe taxis and city vehicles) in just that lane as cars will sometimes still try to use that lane. Also, it's worth allowing the vehicles in the outer most lane to continue straight ahead so buses can stay in that lane and get back into the bus lane without needing to change lanes twice. I know this isn't good practice, but banning the traffic in the bus lane actually mitigates it.

[@lordfaladar6261]

[@krcprc]

That diamond interchange received kinda undeserved reviews... It just wasn't set up correctly :D These interchanges require timed traffic lights to function properly (the same as roundabouts require yield signs). You just use two steps for each direction, super easy to set up, super easy to control the flow (by adjusting the timing for each direction), and super effective (worked for myself).

First, in game they _require_ TM:PE to set up lane connections, timed traffic lights, and junction restrictions, which hadn't been done. Second, they need more space--the section in the middle, visible between the two overpasses, should be at least twice and preferably three or four times as long. In the middle section of a DDI you have through traffic, traffic turning off onto the freeway, and traffic turn off of the freeway all going through the same section. They need at least one node to change lanes in there. Also, on a really busy interchange you can have problems from weaving (where cars turning off of the freeway and cars turning onto the freeway have to change lanes past each other). In that case, you need to add an additional traffic light on each off ramp, synchronized with the main lights at each end of the interchange, so that traffic turning right off the freeway goes while traffic from the minor street is stopped. Of course all this is much more complicated to set up, so unless you're making an American or French themed city (I'm pretty sure nobody else uses DDIs) the roundabout is the easy solution.

@@marceelino Yeah, i could see that there was no setup. The DDI needs a ton of setup.

[@TheRedBanner]

@@kenhagler7166 I understand the DDI very well. It is my go-to for under/overpasses. I'm also a fan of the RCUT, MUT, and the CFI. The roundabout is basically a crutch in C:S, and the way they are typically used does not provide for a realistic city. I like roundabouts (I'm American, and get excited every time a new one pops up), but I have never seen a roundabout highway exit as is typically used in these videos, and as I say this I am looking at Google images just to see, and almost all of the pics are C:S. From a KZbinr who is known for fixing traffic, I would just like to see a hell of a lot more than roundabouts made out of highway roads.

If they're updating the traffic manager mods, would be neat for them to add a Hugo edition that automatically mapped lanes to matching lanes on either side of a node.

I picked up this game and it's just not my cup of tea. However, I love these videos. They're my go-to entertainment every week, and I can't figure out why. I simply just love watching them. Thanks!

[@thegamersmanifesto3671]

I really like Realistic Population Mod, but I don't use much High Density so it tends to make my overall population lower. Throughout the course of this video as well as the disabling of the mod the City went from 160k to 93k... a 60% reduction in population and you might expect about 60% better traffic flow from that alone. Great to see a LHD city though!

[@ZorenManray]

The Diverging diamond interchange can be powerful but is rarely set up properly with traffic manager.. most critical is the lights allowing entry and exit from the counterflow need to be synchronized or it all just backs up into a horrible mess as seen in this video.

[@samh0191]

Hey Biffa, I am asking if you know any image overlay tools that aren’t broken that I could use as I am wanting to start a project recreating a city. Would you know any at all?

[@gemberkoekje]

The diamond junction can work, but only with timed traffic lights so that cars don't get in each others way constantly. In vanilla they just don't work.

[@epiccollision]

Also diverging diamonds are not bad, you just have to micro manage them, round about are dead simple yes, but if you put the work in a ddx can be perfect.

[@BandanaDrummer95]

The really problematic interchange was an attempt at a diverging diamond interchange, which require synchronized stoplights to really work. It also has the issue that it has vehicles enter immediately before vehicles are removed, which has issues that are sort of mitigated if everything is set up correctly and flowing well. Not to mention that it requires splitting a two-way road into two one-way roads, which you've mentioned the U-turn issues with before, but it also has some of those types of things internally, which just screw with the game if you don't connect everything. Also, its main advantages in the real world are safety-related, which isn't a factor in Cities: Skylines. All in all, it's a difficult interchange to build in game that with vanilla can't be set up properly, doesn't even offer that good of advantages if done perfectly, and can easily cause problems if not done properly.

[@BandanaDrummer95]

Also, with this being the second interchange that I have seen you replace completely because not only was it set up wrong to begin with but you couldn't make sense of it, I might be tempted just to make videos on how to build some of the more complicated interchanges. I'd have to make a setup for making videos, but it might work.

[@sanbo20]

There is one part where the lane mathematics is wrong, on the second diverging diamond thing that you adjusted, you can see it at 19:08 and in the before/after part at 23:42 the road heading from right to left is 4 lane highway, then one goes off and two go straight on, should have been one goes off and three go straight on.

I wonder if Biffa’s house floor is using some form of round about between each room. 😄

Biffa, please stop saying, "choc-a-block" because every time you do I crave a block of choc.

Lol 😁

It's still Valentines there? Would be a perfect time for some.

Missed the opportunity to make this "block a choc".

@@krasnamerah1926 No, the perfect time for a block-a-choc is actually February 15th, when all the unsold Valentine's sweets go on sale.
