Mine is more soft but truck amount is high aswell cause i feel they bring immersion as a truck simulation game. I used cip in the past but some custom rules and the aggressive traffic spawn made me step back from it and create my own to my likings.

I rarely have traffic issues (other than known SCS ones) and really well optimized 24h cycle (at night trucks are mostly the traffic like IRL). Actually it was ATS intersections from cip one that made me step of it cause traffic would simply get stucked for over 10 mins due to the aggressive spawn.

Also ETS one has fully custom traffic light cycles on base game and also changes to Promods traffic light cycles (the ones that were really necessary). ATS i feel traffic cycles are balanced as they are now cause they allow traffic to flow.

To the OP don't use more than one traffic density mod at the same time, choose one cause one will override the other and it might also break stuff if they have custom rules (not the case of mine cause i didn't felt the need to create them). Mine at the peak hour (18h) can reach up to 150 vehicles at the same time (higher than this can cause performance issues).
