VTD — Seasonal & Regional Traffic
(REQUIRED: any single “Vanilla+ time zones” mod)
OUTLINE
VTD uses real-world traffic data to give ATS different traffic patterns by season, state, and city.
It also adjusts AI driving behavior to reflect seasonal conditions.
Unlike ordinary traffic density mods, VTD works as an addon to them instead.
You can expect denser traffic in California and lighter traffic in Nevada. Noticeable differences can also be found between Chicago and Springfield in Illinois, or between Houston and Lubbock in Texas—among many other regions.
If you want more realistic American traffic patterns and AI behavior—not simply heavier traffic and lifeless drivers—VTD is the choice for you.
Traffic data sources:
- TomTom — primary source
- Numbeo — secondary source
FEATURES & SCOPE
FEATURES
- Traffic patterns vary across states and cities based on the latest SPRING traffic data.
March – May 2026
- AI driving behavior is adjusted to reflect the SPRING season.
Changes include:
- Overall safety and patience
- Driving-speed variation
- Lane-change distance and duration
- Following distance while driving and idling
- Reflexes and reactions, including smoother braking for escоrt vehicles
- Accident response and hazard awareness
SCOPE
VTD has limited compatibility with ProMods and other map mods.
Regional traffic works in areas covered by the vanilla map, even if parts have been edited or reworked.
However, since city regions were mapped out based on the vanilla map, there may be some inconsistencies when using map combos.
Areas outside the vanilla map are not yet supported.
COMPATIBILITY
Versions: 1.57 onwards
Convoy: Non-optional
