What this mod does

Advanced SCS Traffic is a mod by Bigyarus that slightly increases the stock traffic density in American Truck Simulator. The author wants to avoid the car overload of other traffic mods and keep the neutral behavior of the SCS AI. It has over 32,000 subscribers.

What changes

  • A little more traffic than the stock game, up to what the author calls “the safe point”.
  • More cars during the morning and evening rush hours, and fewer at night.
  • The goal is to keep the AI from getting stuck during heavy traffic or at roundabouts.
  • Driver behavior is still the SCS one.

Load order and compatibility

If you use mods that change traffic spawn rules, like train mods, the author asks you to give it high priority to avoid game crashes. According to the description, it’s compatible with map mods. One user says it threw an error alongside other traffic mods, so the safest bet is not to combine it with other density mods.

Version

The description says it’s updated for 1.58, and the latest update is from February 11, 2026. Several users are asking for 1.60 and 1.61 with no reply from the author. It’s about 102 KB.
