| # 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 | |
