Evacuation Time Calculator
Explicit independently evaluated path travel/exit-service scenarios after detection/premovement, no queue interactions, escape safety or evacuation directive. 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
An evacuation scenario combines detection, premovement, travel and exit-service times.
An evacuation scenario combines detection, premovement, travel and exit-service times.1
Summing supplied components gives a conditional completion time rather than simulating crowd movement or proving evacuation adequacy. Use Evacuation Time Calculator to evaluate the supplied inputs under the specific model below.
When to use Evacuation Time Calculator
Use Evacuation Time 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 Evacuation Time Calculator and understand its results
- Establish the units, measurement scope and applicable model or recipe assumptions before entering values.
- Enter Caller detection seconds, Caller premovement seconds, Caller independent travel seconds, Caller independent exit service seconds using the field table and validation rules below, then run the tool.
- Read Caller scenario exit completion seconds, Maximum caller scenario completion seconds 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 |
|---|---|---|---|
| callerDetectionSeconds | Caller detection seconds | number | Required; constraints below |
| callerPremovementSeconds | Caller premovement seconds | number | Required; constraints below |
| callerIndependentTravelSeconds | Caller independent travel seconds | array of number | Required; constraints below |
| callerIndependentExitServiceSeconds | Caller independent exit service seconds | array of number | Required; constraints below |
Enter nonnegative detection and premovement times in seconds and aligned nonempty arrays of nonnegative travel and exit-service times. For each independent scenario, add all four components, preserve scenario order and return the largest completion time. Exit-service inputs must already embody the adopted scenario; the calculation does not simulate interacting queues or evacuation movement.
completion[i] = detection+premovement+travel[i]+exitService[i]; maximum = max(completion) Field order, units and branch conditions follow the implementation explanation above.
| Output field | Meaning | Value type |
|---|---|---|
| callerScenarioExitCompletionSeconds | Caller scenario exit completion seconds | array of number |
| maximumCallerScenarioCompletionSeconds | Maximum caller scenario completion seconds | number |

}Limitations and assumptions
Summing supplied components gives a conditional completion time rather than simulating crowd movement or proving evacuation adequacy. 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.
