MARS — Region-Aware Multimodal Railway Safety

Interactive Gradio demo for the MARS railway safety system. Users can change track sensor telemetry, weather hazards, video/security anomaly signals, and Indian Railway zone/division context to see how the system fuses multiple modalities into an operational risk decision.

What You Can Try

• Select an Indian Railway zone such as CR, WR, ER, SR, NR, NFR, or NWR.
• Change division-specific context and see the regional operating profile.
• Adjust track inputs: speed, vibration, curvature, temperature, age, maintenance score.
• Adjust weather inputs: rainfall, visibility, wind, heat, flood, fog.
• Adjust video/security inputs: trespasser, obstruction, crowding, camera visibility.
• Run a multimodal assessment and inspect the individual track, weather, and security scores.

Modalities

• Track risk: speed, acceleration, vibration, temperature, geometry, maintenance.
• Weather fusion: rainfall, visibility, wind, ambient temperature, hazard flags.
• Video/security signal: detection confidence for trespassers, obstructions, platform crowding, and low-visibility camera conditions.
• Regional operations: zone-specific factors for terrain, weather, maintenance difficulty, and permitted speed behavior.

Risk Levels

• 🟢 Normal (score < 0.35): Standard operations
• 🟡 Caution (0.35 ≤ score < 0.68): Reduced speed advisory
• 🔴 High Risk (score ≥ 0.68): Speed restriction required
