Tunnels are critical to the transportation infrastructure for the simple reason that traffic cannot get around it

The rerouting of traffic requires an assessment of the impacts to the neighborhoods and communities along the detour, if available. Emergencies originate from accidents, fires, fuel spills, hazardous material releases, earthquakes, floods, rock slides, landslides, severe weather and can happen daily

The safety in tunnels rely on computerized systems and digital interconnected networks to manage incidents. Many lives depend on it and how quick and good the personnel react to emergencies: it’s a must to have the IT equipment always working and protected from cyber attacks. A tunnel security and safety system must be fully operational 24/7, every day of the year
