"Rebalance" is a great mod, but original XML:
-reduce general traffic in the city.
-life x3 is somewhat slow (there are fewer active cims in city).
-increases too many ambulances in the streets (many sicks).


With option mod "legacy", this is my alternative configuration XML:

With this configuration, traffic returns to vanilla traffic, life x2 is more dynamic, and there are more sicks (but not so many).

Posdata.- I not use "Realistic Population Revisited 1.1.1" mod.
