🚇 SD.31.05 • Underground Transport Observability

Underground Transport Observability

Make underground transport AI explainable. Every pod navigation decision, every ventilation action, every emergency response—observable, queryable, and auditable.

"Why did the pod stop in the tunnel?"

Finally, an answer that takes seconds instead of hours.

Structured EventIDs make system-wide incident investigation possible

🛑 Pod Stoppage Investigation

Reconstruct every decision during an unplanned stop

SELECT * FROM events
WHERE event_id LIKE 'vehicle.pod.%'
AND pod_id = 'POD-2803'
AND timestamp BETWEEN
  '2026-01-30T14:00:00Z' AND
  '2026-01-30T14:05:00Z'
ORDER BY timestamp;

🌬️ Ventilation Analysis

Track all environmental control decisions

SELECT tunnel_section, event_id,
  air_quality_ppm, fan_speed
FROM events
WHERE event_id LIKE
  'tunnel.ventilation.%'
AND date = '2026-01-30';

🚨 Emergency Response Audit

Review all emergency system activations

SELECT event_id, trigger_reason,
  response_time_ms, outcome
FROM events
WHERE event_id LIKE
  'tunnel.emergency.%'
AND severity = 'CRITICAL';

📊 Throughput Analysis

Measure passenger flow and system efficiency

SELECT station_id,
  COUNT(*) as boardings,
  AVG(wait_time_sec) as avg_wait
FROM events
WHERE event_id =
  'vehicle.pod.passenger_loaded:1'
GROUP BY station_id;

Incident Investigation: Before vs. After

How structured observability transforms tunnel incident analysis

Without Event Model

1

Incident Reported

Pod stopped in tunnel, passengers waiting

2

Log Collection

Gather data from vehicle, tunnel, control systems

3

Manual Correlation

Engineers piece together timeline from disparate logs

4

Root Cause Analysis

Why did the pod stop? Sensor? Software? Obstruction?

5

Report Generation

Compile findings for DOT / NTSB if required

4-8 Hours

Immediate structured query on pod events

2

Auto-Timeline

Complete sequence reconstructed automatically

3

AI Analysis

Pattern match against historical incidents

4

Root Cause Found

Sensor false positive from tunnel lighting change

Why Underground Transport Observability Matters

Structured events enable capabilities impossible with traditional logging

Passenger Safety Audit

Every stop, every emergency response, every evacuation decision—traceable and explainable.

Fleet-Wide Patterns

Identify systemic issues across all pods and tunnels. Detect anomalies before they cascade.

Regulatory Compliance

Automated reporting for DOT, NTSB, and state transportation authority requirements.

Real-Time Anomaly Detection

ML models trained on structured events identify deviations across the network instantly.

Environmental Monitoring

Track air quality, temperature, and ventilation across all tunnel sections continuously.

Passenger Flow Optimization

Understand boarding patterns, wait times, and capacity utilization across all stations.

Transportation Safety Compliance

DOT, NTSB, and State Requirements

Underground passenger transport systems require comprehensive safety documentation. Event Model provides the structured audit trail needed for DOT compliance, NTSB incident investigation, and state-level transportation authority requirements. Every pod movement, every safety system activation—documented and queryable.
