Reference

IBC 3008 / ASME A17.1: Occupant Evacuation Elevator Requirements Round Trip Time = 2 x Travel + Door cycles + Load + Unload + Accel/Decel Travel time = (Floors x Floor height) / Speed x 60 Door cycle: ~10 sec per stop Loading: ~1.2 sec/person, Unloading: ~1.0 sec/person Trips/hr = 3600 / Round Trip Time
