Austria clarified that this amount is based on the number of kilometres needed to operate according to the schedule including dwell-time, but excluding round-trips to terminal bus stops/garages, rest periods etc. According to Austria, at 21 km per hour Verkehrsverbund Tirol assumed a relatively high number of driven kilometres per hour [15], as the average for Austria is 16-18 km per hour.
Itävallan mukaan Verkehrsverbund Tirolin oletus 21 kilometriä tuntia kohden on suhteellisen korkea [15], sillä Itävallan liikenteessä keskiarvo on 16–18 kilometriä tunnissa.
