I sorry then, take this mod as an addon to Real traffic density, the file included in the Emergency pack is traffic_rules_spawn.sui because I had to add different str_param in order that Ai with hookup sound found at road events won’t spawn on the roads.
you can try my traffic density mod maybe you will even like it and if you don’t and want to keep emergency let me know and I will send to you the spawn file so you can edit it

Unfortunately, I am using my modification on traffic and unfortunately whatever I would not do, it is not compatible with yours. Every time I turn on both mods, the game crashes regardless of the order on the list :(

sorry to hear, normally will work without but still get partially my density from my traffic mod. if you want less traffic, just add in console g_traffic 0.6 or 0.5 and you will get about the default density but with the features for emergency vehicles

these sounds are in my other Steam mod Real Ai Traffic FMOD Sounds ATS forgot to mention it ;)
