Parking demand accumulation calculator

Calculate occupancy after each interval and peak boundary occupancy with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use occupancy after each interval and peak boundary occupancy to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Occupancy after each interval (JSON)

Boundary occupancy accumulation; arrivals/departures within an interval are netted, so within-interval peaks are not resolved.

Peak boundary occupancy (spaces)

Boundary occupancy accumulation; arrivals/departures within an interval are netted, so within-interval peaks are not resolved.

Peak excess over capacity (spaces)

Boundary occupancy accumulation; arrivals/departures within an interval are netted, so within-interval peaks are not resolved.

Symbols and units
a
Starting occupied spaces (count)
b
Arrivals by interval (counts)
c
Departures by interval (counts)
d
Parking capacity (spaces)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • User-supplied measurements and assumptions; Boundary occupancy accumulation; arrivals/departures within an interval are netted, so within-interval peaks are not resolved. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
