Proper Traffic Variety (1.40, 3/21/21, Montana Expansion Support)

March 22, 2021

ATS’s traffic variety is well and all, but could it be more accurate? This mod makes a minor change, but it certainly makes the game more accurate.

I’ve sifted through thousands of Craigslist ads for each vehicle’s year, make, model, and, when applicable, trim, counted every individual vehicle, and factored it into each vehicle’s spawn ratio. For vehicles belonging to a specific department or company, I’ve taken a sample for each state, and factored what vehicles are present in that sample into each vehicle’s spawn ratio.

Resolving incompatibilities:
-You may have to place the mod beneath traffic packs.
-Place beneath Brutal Traffic (maintains in-class traffic variety while allowing Brutal Traffic’s density).
-Place beneath ATS Traffic Behaviour (maintains in-class variety while allowing Traffic Behaviour’s density).
-Place beneath Meatballs Traffic Density Mod (maintains in-class variety while allowing Traffic Density Mod’s density).
-Place above Realistic traffic (allows the spawn of modded traffic vehicles while overriding his edits to spawns).
-Place below Real Traffic Density (allows Traffic Density’s density, while keeping in class variety).
-Place above Island Map to ensure the mod takes effect.

Features include:
-Vastly decreased semi spawn.
-Vastly decreased police spawn.
-Vastly decreased bus spawn.
-Vehicles not sold in the United States no longer spawn.
-Vehicles unrealistic fleet vehicles no longer spawn (some fire trucks, 2012 CHP Charger, etc.).
-Outdated fleet vehicles no longer spawn (MCI MC-12, NHP Crown Victoria, etc.).
-As previously stated, every spawn ratio is grounded in empirical data, at least somewhat accurately portraying the car culture of each state. For example, California has a greater preponderance of electric vehicles, while other states have an increased number of pickups.

Supported maps:
-Island Map
-Montana Expansion

-Utah’s lack of variety and some vehicles being far too prolific has been largely been corrected, but some issues still remain.

Other notes:
-Compatible with all map mods, traffic packs, and DLCs, however, map mod traffic isn’t effected.
-Since traffic pack’s aren’t optimized for this mod, and it may cause issues with traffic spawning. This is especially true for Utah, where spawn ratios have been greatly altered (normal spawn ratios hover around 0.5-1.00, but I’ve had to multiply this by 100 for each vehicle) to combat measures hard-coded into the game.
