Vehicle utilization is described as "total vehicle on-street time divided by total trip duration for all vehicles"
Here's an example of one day of data:

Let's say there are 10 operational hours in this day. Then total vehicle on-street time = 624 vehicles x 10 hrs = 6240 hours
Total trip duration for all vehicles = 22m7s per trip / 60 min per hr * 544 trips = 200 hours
I think there's an error in the description; the numerator and the denominator should be reversed, otherwise you'll always get a utilization of over 100%. But even if I do that, I'd have:
utilization = 200 hours / 6240 hours = 3.2%. Not 34%, like in the example.
I think the calculation has a math error somewhere.
