Delhi Metro operates advanced driverless trains (Unattended Train Operation - UTO) on lines like the Magenta and Pink Lines. Without a driver inside the cab, real-time safety, obstacle detection, crowd management, and passenger emergency response become critical. Build an open-source tool, web dashboard, or AI prototype that addresses autonomous metro challenges—such as real-time platform obstacle detection alerts, an AI chatbot for offline metro route/first-aid assistance, platform edge door (PED) monitoring simulation, or an automated passenger density tracking system.
