[REL] Urban Traffic Overhaul (Formerly "Minor Urban Overhaul") (05/24/2026)

[Quaristice]

This is just something I've been only making for myself for some time, but decided to make public now.

This mod greatly increases traffic density in major urban areas across the map; traffic elsewhere is kept to vanilla levels, which I think is realistic enough.

While this mod is closer to a traffic mod than a map mod, busy areas with increased traffic spawns have to be defined manually in the map editor, requiring map edits, simply modifying definition files to increase traffic spawn rates and limits like a lot of "realistic traffic" mods do would make the whole map busy with traffic, from major cities to unpopulated rural areas, that's why editing the map itself is necessary for decently realistic traffic density.

This mod also widens freeways and urbanizes some areas of Phoenix, just a small touch-up I've done years ago as that area has always bothered me in terms of accuracy. Use the available "Lite" version if you want only the scenery changes in the Phoenix Area and no edits to traffic density in cities.

As this mod has modified sectors in major urban areas throughout the whole map, all map DLC is probably required.

(For compability with traffic spawn mods simply open the mod with a file archiver (7-Zip, WinRAR, ...), open the "def" folder and delete "traffic_data.sii" and "traffic_rules_spawn.sui" inside its "world" folder)

Edited areas in the mod detailed in the map below:

Should be compatible with minor map mods if you put them in higher priority.

Looks great! Did u by chance try it with US Expansion? only mod i would think it may conflict with. I'll try it out and see if it works.

[bobgrey1997]

I LIKE THIS!
I'll be sure to try it out when I get my game working again.
Thank you for not using ShareMods!

[Drive Safely]

Good ideas! I might try this out

Since this mod affects traffic density, is it not compatible with Cipinho’s traffic mod?

[Timbah]

Testing it for compatability with US Expansion... It crashed when i travelled to my garage near San Diego. Trying to drive there now but driving from portland xD Might take a while but i've just gone through Redding and about halfway down towards Sacramento with no issues.

Seems to be a conflict with something upon nearing San Diego:

Crash Log.txt

Everytime i come to this corner it crasehs and the above is in the log.

This is the corner it crashes at in game:

I just ran from San Diego up to Los Angeles. No crashes and the drive was quite nice. No other map mods.

Thanks for this Quaristice.

[TexasWhirlwind]

Instead of posting a worthless crash log try posting the complete game.txt.log with pastebin... It will tell what is going on...

[Timbah]

Apologies i didn't know crash logs were worthless...

Here is the pastebin

https://pastebin.com/dKf4HR5X

This mod is conflicting with something or is causing some kind of error as this area was fine before installation. Should i mention i'm running on DX11 or is that worthless too?
