Definition of utilization A utilization metric can be calculated to estimate the level of parking purchases in a given time interval.

As this utilization calculation is based only on the time at which parking is purchased, it does not represent a good estimation of the occupancy of a particular lot or zone. (Specifically, if someone pays at 8am for four hours of parking, all of that revenue is counted in the 8am-10am slot in this calculation, even though a parking space was paid for through noon.)

The formula used for calculating utilization is
Utilization = (Revenue from parking purchases during time slot) / (Revenue if all spaces are paid for during time slot)

Transient utilization (utilization excluding lease revenue and spaces) would be
(Revenue from parking during time slot) / { (space_count - 0.85×lease_count) × (rate per hour) × (the number of days in the time span where parking is not free) × (duration of time slot in hours) }

Here we assume 85% occupancy of leased spaces as a reasonable estimate. (space_count - 0.85×lease_count) is an effective space count (the number of parking spaces expected to be available for everyday purchase). By adding in the lease utilization, we can calculate the total utilization:
Utilization = ([Transient utilization]×[effective space count] + 0.85×lease_count)/space_count
    = (Revenue from parking purchases during time slot) / { space_count × (rate per hour) × (the number of days in the time span where parking is not free) × (duration of slot in hours) }
      + 0.85×lease_count/space_count
or more concisely:
Utilization = revenue / (space_count × rate × days × hours) + 0.85×lease_count/space_count
