Real Traffic Density patch for Jazzycat/TrafficMan vehicles for American Truck Simulator

What this mod does

Real Traffic Density patch for Jazzycat/TrafficMan vehicles is an add-on by Erbkaiser for anyone combining Cipus’s Real Traffic Density with the traffic vehicle packs by Jazzycat (TrafficMan).

What it does

• Correct vehicle types: the motorcycles, classic cars and sports cars in those packs get their own type, so Real Traffic Density treats them as what they are instead of regular cars.
• Parking: all of those vehicles, except motorcycles, can show up parked.

Requirements and load order

It needs Real Traffic Density, which Steam lists as a requirement. If you don’t use it, none of those vehicles will appear. The order is: Real Traffic Density at the top, this patch below it and the Jazzycat packs further down. If you use other mods that change Jazzycat vehicles, place them above the patch but below Real Traffic Density; the parking changes aren’t compatible with them.

If you don’t have every pack

You can still use it: missing vehicles are ignored. The game log will show missing-file errors, which is normal, although on a heavily loaded PC it can cause the odd stutter. If Jazzycat adds new vehicles, the author will update the patch. There’s also an ETS2 version.

Requirements

• American Truck Simulator 1.61 (the author doesn't list a version; released in September 2026)
• Real Traffic Density (Steam Workshop, ID 1213282672)
• Jazzycat/TrafficMan traffic packs (whichever you want to use)

How to install it

1. Subscribe to Real Traffic Density and this patch on Steam Workshop.
2. Subscribe to the Jazzycat packs you want to use (motorcycles, classics, sports cars).
3. In the Mod Manager, put Real Traffic Density at the top, the patch below it and the Jazzycat packs further down.
4. Ignore the missing-file warnings in the log if you don't have every pack.
