- Passengers to exit platform
- 500
- Measured effective flow per open exit (people/second)
- 1.5
- Open identical exits
- 3
- Added observed pre-movement delay (seconds)
- 20
- Ideal constant-flow clearing time (seconds)
- 111.111111
- Time including entered delay (seconds)
- 131.111111
Try another scenario
- Passengers to exit platform
- 501
- Measured effective flow per open exit (people/second)
- 1.5
- Open identical exits
- 3
- Added observed pre-movement delay (seconds)
- 20
- Ideal constant-flow clearing time (seconds)
- 111.333333
- Time including entered delay (seconds)
- 131.333333
Calculation method
Calculation method
Ideal constant-flow clearing time (seconds)
Flow time=people/(perExitFlow×exits); add user measured delay.
Time including entered delay (seconds)
Flow time=people/(perExitFlow×exits); add user measured delay.

Assumptions & limits
Assumptions & limits
- Illustrative homogeneous flow only; no crowd dynamics, queue interactions or evacuation safety certification. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Illustrative homogeneous flow only; no crowd dynamics, queue interactions or evacuation safety certification.
