About this mod

Real Traffic Density sets how many AI vehicles appear using real-life traffic data, tuned to what the game can handle. Big cities and motorways get busy, small towns stay quiet, and night traffic drops off, except on motorways.

It also changes AI behaviour: drivers sometimes speed (by up to 35%, within each vehicle's own limit), emergency vehicles, motorcycles and sports cars get their own speeds, traffic lights run longer cycles on big roads, and AI can overtake on single solid lines on two-lane roads. It's free and works with the base map and all map DLCs.

Features

  • Spawn rates based on real-world traffic charts
  • Fewer spawns at merges to reduce traffic jams
  • Longer signal cycles on large roads, shorter on small ones
  • Less traffic at night, except on motorways
  • Different densities for small and large cities

How to install Real Traffic Density

  1. Open the mod's Steam Workshop page (sign in to Steam if asked) and press Subscribe. Steam downloads it for you.
  2. Start Euro Truck Simulator 2. On the profile screen, open the Mod Manager.
  3. Find Real Traffic Density in the list and move it to Active mods, then press Confirm changes.

Load order: Put it above map mods and any other mods that change traffic density, including graphics mods. It's meant to sit above ProMods and MHA Pro Map.

Notes for this mod

  • Leave the game's traffic density (g_traffic) at 1. You can go lower, but not below 0.5.
  • With many traffic packs at high density the game can crash with "Failed to assign pool segment". The authors' fix is the Steam launch option -mm_pool_size 16384 (about half your RAM in MB).
