This is a video of the first iteration of the 3D simulation of Gotthard Tunnel station that Simudyne is building to support the EU funded SAVEME project. SAVE ME aims to develop a system that detects disaster events in public transport terminals / vehicles and critical infrastructures (i.e. tunnels and bridges) and supports quick and optimal mass evacuation guidance, to save the lives of the general public and the rescuers, giving particular emphasis to the most vulnerable travellers.
