Peak Hour Visitor Flow Congestion Index Calculator
Reconstruct observed interval-boundary visitor inventory from separate arrivals/departures and compare caller comfort occupancy; no hidden Little’s-law steady state, within-interval peak, fire-code approval or crowd safety.
Description
Arrival and departure ledgers reconstruct visitor inventory at interval boundaries.
Arrival and departure ledgers reconstruct visitor inventory at interval boundaries. They cannot reveal a higher peak within an interval.
Reconstruct observed interval-boundary visitor inventory from separate arrivals/departures and compare caller comfort occupancy; no hidden Little’s-law steady state, within-interval peak, fire-code approval or crowd safety.
When to use Peak Hour Visitor Flow Congestion Index Calculator
Use this tool to reconstruct observed interval-boundary visitor inventory from separate arrivals/departures and compare caller comfort occupancy; no hidden Little’s-law steady state, within-interval peak, fire-code approval or crowd safety.
Prepare the collection, exposure, scheduling or financial records required for this calculation. Keep row order and the declared units consistent.
How to use Peak Hour Visitor Flow Congestion Index Calculator and understand its results
- Prepare the collection, exposure, scheduling or financial records required for this calculation. Keep row order and the declared units consistent.
- Enter arrivalsByInterval, departuresByInterval, initialVisitorCount, callerComfortOccupancy using the field table and calculation rules, then run the tool.
- Read visitorCountsAfterIntervals, peakObservedOccupancy, peakToCallerComfortIndex. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| arrivalsByInterval | Arrivals by interval | list of number | Required |
| departuresByInterval | Departures by interval | list of number | Required |
| initialVisitorCount | Initial visitor count | integer | Required |
| callerComfortOccupancy | Caller comfort occupancy | number | Required |
Align nonnegative integer interval counts with nonnegative initial occupancy. Reject negative reconstructed counts, include initial occupancy in the peak and divide by a positive caller comfort capacity.1
Paired lists must be nonempty and have equal lengths.
next occupancy = previous + arrivals − departures Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| visitorCountsAfterIntervals | Visitor counts after intervals | list of number |
| peakObservedOccupancy | Peak observed occupancy | number |
| peakToCallerComfortIndex | Peak to caller comfort index | number |

}Limitations and assumptions
No within-interval peak, fire-code or crowd-safety approval is supplied.
Numbers and computed results must be finite; overflow produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Gallery Route Loop Length Walking Time Calculator: Budget segment-specific walking exposure plus independent stop/queue ledger, rather than one average-speed geometric route; no accessibility, evacuation or visitor timing guarantee. For a complementary task, use Audio Guide Device Charge Cycle Fleet Sizing Calculator: Budget steady continuous tour-device demand plus recharge/reset pipeline and caller ready reserve; assumes stable turnover and enough chargers, not exact peak queue sizing or battery life guarantee.
