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 compability 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: 1.55.x

21.0 Changes:
• Multiple sectors bordering Iowa and Illinois refreshed to avoid CTDs due to new dev-side map edits.
• Broken ShopTown stores fixed across the map.
• AI behavior changed so that AI vehicles that crash into each other should immediately recover and resume driving, to minimize merging issues that come with increased traffic.
