No. 03 · Crowd safety
Stampede pre-emption,
at the scale of a Kumbh.
SAFER reads density, flow and behaviour across the world's largest gatherings — and pre-empts the cascades that turn a crowd into a casualty count. Validated in field at Mahakumbh, Hajj corridor and metro interchanges.
Capabilities
What SAFER reads, in real time.
01
Density mapping
Persons-per-sq-m heatmap, refreshed sub-second across thousands of square metres.
02
Flow forecasting
Where the crowd is going next — and where the bottlenecks will form.
03
Stampede pre-emption
Pressure-wave detection. Alerts fire before a cascade reaches critical density.
04
Field dispatch
Closest patrol routed automatically, with the alert reasoning attached.
05
PA orchestration
Targeted announcements per zone, multilingual.
06
Post-event review
Replay any minute of the event with full sensor context for learning.
