Example: You sort 100 vehicles ascending according to speed. The speed of the 86th vehicle
corresponds with the value v85. You can therefore see whether the majority of drivers abide by
the speed specified by the StVO (German Road Traffic Regulations).
If 85% of all vehicles adhere to the permissible top speed of e.g. 50 km/h, then this speed is
considered to have been accepted by road traffic. If the value v85 is clearly above the permissible
top speed, traffic planning/traffic calming measures should be taken.
