Escalator Capacity Calculator
Step throughput with independently observed occupancy/duty, not an equipment passenger safety rating. Caller independently establishes units, regime, calibration and applicability; this does not establish design-code compliance, authenticity, operational safety, treatment efficacy or a validated forecast.
Description
Escalator throughput depends on step speed, step spacing and observed loading.
Escalator throughput depends on step speed, step spacing and observed loading.1
An operating fraction scales the modeled hourly rate without establishing the equipment's allowable passenger capacity. Use Escalator Capacity Calculator to evaluate the supplied inputs under the specific model below.
When to use Escalator Capacity Calculator
Use Escalator Capacity Calculator to evaluate the supplied inputs under the specific model below. Establish the units, measurement scope and applicable model or recipe assumptions before entering values.
How to use Escalator Capacity Calculator and understand its results
- Establish the units, measurement scope and applicable model or recipe assumptions before entering values.
- Enter Observed escalator step speed m second, Observed step pitch m, Caller observed mean passengers per step, Caller operating fraction using the field table and validation rules below, then run the tool.
- Read Modeled observed escalator passengers hour and interpret units, signs, ordering and placeholders as explained below.
- If the tool reports an input error, correct that field and rerun. A successful false result, empty match list or unknown-evidence placeholder has the specific meaning described here; check the limitations before applying the result.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedEscalatorStepSpeedMSecond | Observed escalator step speed m second | number | Required; constraints below |
| observedStepPitchM | Observed step pitch m | number | Required; constraints below |
| callerObservedMeanPassengersPerStep | Caller observed mean passengers per step | number | Required; constraints below |
| callerOperatingFraction | Caller operating fraction | number | Required; constraints below |
Enter a positive step pitch in m, nonnegative step speed in m/s and mean passengers per step, and an operating fraction from 0 to 1. Convert steps per second to steps per hour, multiply by mean loading and scale by the operating fraction. Fractional mean loading is accepted; no load, access or equipment rating is inferred.
passengers/hour = 3600×speed/pitch×meanPassengersPerStep×operatingFraction Field order, units and branch conditions follow the implementation explanation above.
| Output field | Meaning | Value type |
|---|---|---|
| modeledObservedEscalatorPassengersHour | Modeled observed escalator passengers hour | number |

}Limitations and assumptions
An operating fraction scales the modeled hourly rate without establishing the equipment's allowable passenger capacity. Apply the exact scope and assumptions described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are stated above; extremely large inputs or outputs can also be rejected. These errors differ from successful results such as false, no matches or unknown evidence.
