Description
Measure a supplied commute-stop activity's dwell duration.
Geographic activity records depend on location precision, boundary vintage, observation time, population denominator and access-window conventions. A travel-time budget differs from actual accessibility, and rectangular cell area does not establish privacy. Local shares and labels need the original survey and spatial definitions.
Measure a supplied commute-stop activity's dwell duration.
When to use this tool
Use Commute Stop Activity Dwell Time when you already have arrivalTime, departureTime and need to measure a supplied commute-stop activity's dwell duration.
How to use the tool and how it works
- Enter arrivalTime, departureTime. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read dwellTime. Use the output convention below.
Require departureTime>=arrivalTime; return departure-arrival in the same time coordinate.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| arrivalTime | Arrival Time | Required. Finite number. |
| departureTime | Departure Time | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| dwellTime | Dwell Time | Required. Finite number. |

}Limitations and assumptions
- No stop, activity, clock convention or real travel behavior is detected.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use the actual route, service schedule, survey frame and boundary source when assessing mobility or access. Review disclosure across the full spatial dataset and linked records; a location label or cell-size product is not a complete privacy method.
