Incident ModelTransit Capacity & Flow

Crowd Surge Analytics.

Stairwell bottlenecks and platform crushing build in seconds. DHI continuously reads human density per square meter and the speed crowds are moving, giving transit control rooms the warning they need to divert traffic before a landing reaches a dangerous load.

Logic Validation

Crowd Surge Analytics requires precise computer vision engineering.

Verify the specific neural thresholds and VMS integration triggers used to automate this safety protocol.

Density Mapping

Real-Time

Stairwell bottlenecks and platform crushing build in seconds. DHI continuously reads human density per square meter and the speed crowds are moving, giving transit control rooms the warning they need to divert traffic before a landing reaches a dangerous load.

Edge Inference

On-Prem

Square-Meter Thresholding: Warns control rooms instantly if an escalator landing exceeds safe occupation limits.

Integration fit

Gate Control & PA Automation

When localized crushing is detected below ground, the system triggers VMS alerts that allow operators to pause upper-level ticket turnstiles and deploy automated PA announcements immediately.

Failure mode coverage

Transit Capacity & Flow

Flow Velocity: Measures the average speed of mass movement. A sudden drop to zero inside a tunnel triggers a blockage alarm.

Use-case fit

100%

Zero Facial Retention: DHI only processes structural mass and velocity, maintaining total commuter privacy.

Direct answer

What should a crowd-surge AI system detect first?

A crowd-surge AI system should detect pressure building at choke points before it becomes a visible incident. DHI reads density, flow slowdown, queue spillback, and stoppage from approved cameras, then routes events to operators who can redirect movement.

Choke-point fit

The best first cameras cover escalator landings, stairwells, platform entries, fare gates, tunnel mouths, and concourse pinch points.

Operational action

A useful crowd alert supports a concrete action, such as opening overflow paths, pausing gates, changing escalator direction, dispatching staff, or issuing a targeted PA message.

Privacy fit

The system should measure structure, density, and flow. It should not depend on identifying commuters.

Pilot proof

The pilot should measure density thresholds, flow slowdown, false alarms, and whether operators act before crowd pressure reaches the platform edge.

Pilot assumptions to validate

  • Camera views show the full choke point and not only a cropped queue segment.
  • Operations defines which density or flow conditions require action before pilot review.
  • Alerts are tested during peak periods, disruptions, or event release when crowd pressure is real.

Passenger-flow fit

Crowd analytics is about pressure building at choke points, not counting people for a dashboard.

This use case is written for transit environments where density, flow velocity, and sudden stoppage indicate a safety condition before anyone has fallen or crossed a platform edge.

Primary scene

Best camera positions cover escalator landings, platform entrances, concourses, tunnel mouths, fare gates, and stairwells where density changes quickly during service disruption or event release.

Operator action

Alerts should support operational moves such as pausing gates, changing escalator direction, opening overflow routes, dispatching staff, or making a targeted PA announcement.

Pilot measure

A crowd pilot should measure density thresholds, flow slowdown, queue spillback, and how often operators act before a choke point turns into platform-edge pressure.

Detection Logic

  • Square-Meter Thresholding: Warns control rooms instantly if an escalator landing exceeds safe occupation limits.
  • Flow Velocity: Measures the average speed of mass movement. A sudden drop to zero inside a tunnel triggers a blockage alarm.
  • Zero Facial Retention: DHI only processes structural mass and velocity, maintaining total commuter privacy.

Industrial Privacy & Sovereignty

DHI's models do not stream raw video to the public cloud. All safety inferencing occurs on-premise within your local network, supporting privacy review and tighter control for critical infrastructure environments.
