VTD — Seasonal & Regional Traffic

(Please visit here for the complete changelog, as I’m deleting old versions once a new one is released.)

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 FALL traffic data.

September – November 2025

• AI driving behavior is adjusted to reflect the FALL season.

Changes include:
- Overall safety and patience
- Driving-speed variation (speeding may occur)
- 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

• Vanilla map area

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

Please check the images at the top of this page for the correct load order and other requirements.

INCOMPATIBLE

Placing them at a higher priority will prevent my mod from working; you need to choose either mine or others.

• Driver behaviour/traffic flow mods
