Cities Skylines: Can anyone recommend a good industry layout?

[Noth]

I've been struggling with traffic in my industry area! It's painful, but the traffic flow is currently at around 84% because I've managed to make a lot of highway connections and utilise the traffic manager mod. However, I've noticed in YouTube videos that most people have a general idea of an industry flowing one-way rather than having two-way roads. What's the purpose of this? Is there a stock-standard reliable road layout?

I do have one which works really well.

the main trick is you do the 2 big intersections like I show in the picture.

Where the offices are you could put a trainstation, metro, or tram.

Thanks, I’ll give that a try!

I think there's a few reasons:
- It keeps trucks from turning around, which they're not very good at.
- It keeps trucks from turning left to make a delivery, which blocks both lanes.
- It gives a lane for the left side of the street and one for the right side.
- One-way intersections have fewer conflict points, making traffic flow simpler.

Something I've been meaning to try, but don't think I've tested yet:

The idea there is that for every square neighbourhood, traffic enters by small roads on two opposing sides, and leaves by the large roads on the other two sides, and it has full Lane Mathematics so there's minimal conflicts inside.

Also, if you're doing Industries DLC buildings (as opposed to zoned industry), check out this:

It gives much wider sidewalks so that trucks can unload without blocking other traffic on the road.

Akruas built a beautiful (if you can call it that) industrial zone at https://youtu.be/l6IdbqUkDlc

Key takeaways for me:

1. Wide one-way streets, and using Traffic Manager, to prevent delivering trucks from blocking through trucks.

2. Distribution roadways designed to prevent traffic from crossing over each other - trucks margin in from right don't soon exit to left.

3. He doesn't actually say this, but note what direction trucks enter and leave cargo rail terminals, and position them on one-way roads so trucks leaving don't cross the path of trucks entering.

4. Provide passenger trains, (or monorails, or dedicated bus roads) for workers to keep all of their personal cars out of the industrial zone.

Thanks heaps! I'll see what fits best in my city and watch that video for reference as well!

My attempt to get less dense traffic is less dense zoning. So in my industry areas I mark 4x4 tiles, then leave 4 tiles free space whilst marking another 4x4 on the other side of the road. And I mix industry and high density commercial to keep the supply chain short (hoping the company which needs someting is next door or down the street).

I whipped something up quickly for you:

Separating the roads going onto the roundabout is a good idea for traffic speed (it avoids 90-degree angles) and Lane Mathematics (note the dedicated leave-the-roundabout lane on that even without TMPE) anyway.

To avoid bottlenecks I've taken to using Perafilozof's highway change side in combo with roundabouts and one-way roads, but I'm still working on finding the ideal layout.

I'm really not a fan of the direction changer. If you're willing to go 3-levels you don't need traffic to change sides -- you can just raise one side and run whatever road off it you might want.

Changing sides can be useful in a 2-level interchange, though, like

Just put the URL of the screenshot in your post. For example,

ends up looking like this:

Looking at that screenshot, I'm worried that the crossover is pushing you towards very adhoc ramps. It's really easy that way to end up in a situation where there's no good way to get on or off the highway in one of the directions...

To avoid confusion I suggest LHT and RHT: https://en.wikipedia.org/wiki/Left-_and_right-hand_traffic

I agree. No reason to cross over per Perafilozof. Just elevate one side higher than the other. Even leave the other on the ground.

I like this one, which uses one-way streets at the entrance/exit, and uses a separate entrance/exit location to spread out traffic:

I've seen video of that IHT flowing really elegantly. It looks like it's calling out for an update to add some Lane Mathematics to it, though -- it's a real waste to have two 6-lane one-way roads joining into a single 6-lane road. Would be nicer as 2+2+2 -> 6, or 3+3 -> 6 using NExt2 or

Lane Mathematics, however, reminds me of another thing I tried:
https://steamcommunity.com/sharedfiles/filedetails/?id=2111160519
(No workshop item, but it's really easy to build in the intersection editor)

Worked surprisingly well -- the lane math encourages traffic to come in on a lane corresponding to where it's going -- except that I couldn't come up with a good way to get it service coverage. Hopefully someone here can come up with more than I could
