Real Traffic Density and Ratio 1.36.x

Changelog
Mod updated for 1.36 beta

mod never modifies the country speed limits, the speed limits files are included in my mod because in urban expressways cars speed limit is in most of the EU cities raised to 70 km/h instead of 50 km/h therefore this adjustment is absolutely justified.
In my mod, in the country folders you can find also another speed_limit file called speed_limits.high.sii this file ONLY increases the speed limits for emergency vehicles, motorcycles and sport cars, that are allowed to drive faster than the normal vehicles.
