Goods not being delivered - Please help!

[Dabulous]

I guess I must not understand how the supply chain works in this game?

All of my general industry is going out of business because of not enough buyers for products.

All of my commercial buildings are going out of business because of not enough goods to sell.

This is happening city wide, but as you can see in the screenshot it's even happening where the zones are right next to each other and connected by multiple large roadways.

I've been eliminating traffic bottlenecks everywhere and traffic seems to flow pretty smoothly.

I also have an extensive network of above and below ground railroad connecting cargo rail hubs everywhere. I see tons of trains going back and forth and delivery trucks pouring out of the rail stations.

So why does there still seem to be a disconnect between my overproducing factories and the stores with empty shelves?

There are a few reasons for supply chain issues. Because your city is quite big the reason is likely one of the more obscure ones: hitting the game's vehicle limit. Industry and commercial is impacted first because their simulation relies on active agents (vehicles etc.) more than other aspects of the game.

There's a vehicle limit? So what's the mod to override this so high that smoke starts pouring out of my PC?
Edit: It appears also that you are correct. I didn't think My city was THAT big yet. Surely I've seen plenty of screenshots of larger cities than mine. How do people do it?

OK lrts start with the basics again. First question what sort of commercial are you talking about ? the blue zoned generic commercial or office space?

High (and some low) density commercial zones.

Instead of replaying the 20 question game all over again why don't you save everyone a bit of time and share your save. And yes there's a mod to raise the vehicle limit, but you won't like it. a mod to do what you're asking for does NOT exist. Even if it did the game would start smoking long before your computer did. And besides you don't need more than 16k running around anyway. I build cities of 700 - 800k all the time where I broke the 16k limit before the first citizen moved in.
The 16k limit doesn't mean that your city must shut down. It doesn't keep people from moving in or even keep you from zoning more residential. It only means that the people who do will need to walk or find an alternative mode of transportation. Most of them at it turns out seem all to happy to walk about the distance of 1 - 1 1/2 tiles. You can easily cover a twenty-five tile map with a subway grid spaced from 50 - 60 u apart that your citizens and tourists will be happy to use.

Found it. Love it. My hardware can take it and so can my city streets. You didn't need to be a ♥♥♥♥.

That's not what I mean. It says 64K if memory serves which is a lot easier to get to than you might think but the problem is or you may find that that 64k often turns out to be a bit over optimistic. But yes it will get you past 16k and yes your system can surely handle it with no problem. But no it won't set your world on fire. So when you ask "what's the mod to override this so high that smoke starts pouring out of my PC?" I reply that mod does not exist. and for that I get to be a ****.

Thank you Very Much.

You have way too much industry. It is much better to have several small areas spread around the city to ensure fast delivery to commercial areas. You need to get rid of some of it

One thing people do is set up mass transit, trains or subways, to move cims around the city. Others also get people to walk as cims will walk a long way. Give them walking/biking paths so they do not use their cars.

Oh I have a TON of public transit. Very efficient with lots of transfers between bus stops and subway stations. The issue was the vehicle limit. My city is starting to come back to life thanks to More Vehicles mod. Currently approaching double the game limit of 16,383 vehicles and my industrial and commercial areas are about 50% back to life. No major traffic jams yet, on the roads at least. My railways are clogged up and I'm going to have to start looking for railroad assets to handle more traffic.

9.4 GB RAM currently being consumed by the game. Not bad considering...

Almost 50k vehicles on the road and things are just humming along. :D

Had to double available path units with More Path Units mod.

You can also fix this kind of problem by shortening the paths those vehicles must take.

When each trip is shorter you will get more deliveries completed while staying within the default limits. Obviously you cannot put a road directly connecting every industrial building to every commercial building, but you can improve connectivity in that city. Elevate the highways and build regular roads underneath to connect neighborhoods on either side. Make the block lengths shorter so that every trip using those roads can be shorter.

City grids are the best compromise between density and connectivity on a 2D plane. Most cities use rectangular or square blocks because these are simple to build and navigate. In principle a hexagonal grid might be even better (you would need less road to serve the same area), but those almost never happen in the real world.

If you want something more interesting than a simple grid, there are a number of modifications that have been tried over the last century. Lollipops, loops, etc: https://web.archive.org/web/20150225013409/https://www.cmhc-schl.gc.ca/publications/en/rh-pr/tech/socio75.html#Figure7

These compromise the grid, lengthening the average trip length somewhat, but used in moderation they can be nice in residential areas. Your city looks to be using the “warped parallel” style mentioned in that review document, but broken up by the highways. I like the hybrid layouts they propose in figures 4, 5, and 7 in that review.
