Urban Traffic Overhaul v24.2 1.59 ATS

---

Changelog
Emergency hotfix (v24.2)
Broken companies in East St. Louis have been fixed.
Typos for Tucker Boulevard in East St. Louis and St. Louis have been fixed.
The start of rush hour changed from 5 AM to 6 AM.

v24.1
Illinois DLC implementation.
Unrealistic frequency of Hummers in AI traffic fixed.

Maintenance update for 1.59 available (v24). I don’t think v23.1 crashes 1.59, but the introduced map errors have been pruned and whatever small cumulative tweaks made to the map and settings since then are now public.
Running v23.1 with Illinois enabled probably results in broken sectors near St. Louis, too, as those have been edited and in v23.1 are in the same state as they were when Missouri released.

This mod greatly increases traffic density in major urban areas across the map; traffic elsewhere is kept to vanilla levels, which I think is realistic enough. It also widens freeways and urbanizes some areas that are particularly inaccurate in the original map. Use the available “Lite” version if you want only the scenery/signage changes in California and Phoenix Area.
(For compatibility with traffic spawn mods, simply open the mod with a file archiver (7-Zip, WinRAR, …), open the “def” folder and delete “traffic_data.sii” and “traffic_rules_spawn.sui” inside its “world” folder)

All map DLC required
Compatible: 1.59.x
