What this mod does
RealRoads AI Traffic – Real World AI Traffic Light by snazzyatoms is the light preset of the RealRoads series, whose Medium and Heavy Rush Hour versions are already on Holymod. It lowers traffic pressure, relaxes rush hours and leaves the roads quieter at night, with smoother AI safety, patience and yield timing.
What’s included
- A standalone traffic density and behavior preset (only 41 KB).
- Keeps SCS speed-limit and truck rules; it does not replace map sectors, prefabs or the base traffic_rules.sii.
- Works with ProMods and large map combinations.
Load order and version
Use only one RealRoads density preset at a time (Echo Flow, Light, Medium or Heavy), because they edit the same files, and place it above other traffic-density mods or remove them. When testing, keep g_traffic at 1.0. In Convoy, host and participants must use the same version and mod order. Published May 3, 2026, and updated November 8, 2026; the author does not name a specific ATS version, but uses the base vehicle type to stay compatible with the current version.
Known issue: the AI sometimes hesitates at signals or sits at a green light until you reload; the author attributes it to the base game.
