69A3551747111The goals of this project include building Digital Twin city models, implementing real-time traffic overlays, and rendering mobility scenarios in extreme conditions. We have built digital twin models of downtown Pittsburgh, the UPMC STAT MedEvac helicopter launchpad, and the EMS commanding center. These models were based on 3D scanning of real-world scenes and rendered in Unity (a cross-platform computer game engine) and C++ environments. We have overlaid ambulance routing sample data on Digital Twins via the MQTT protocol, and we have tested it on our 3D visualization platform. We tested the helicopter launchpad model with normal pre-flight checklist procedures, and in extreme situations such as escaping fire incidents and deploying the fire-extinguishing-cannon. Small affordable IMU (Inertial Measurement Unit) based 6-DOF sensor modules attached to the user\u2019s foot are used to implement realistic gait detection and avatar motion in the VR simulator
