Transportation Systems

The Transportation Systems critical infrastructure sector includes the people, assets, networks, and supporting services that move passengers and freight across the United States, spanning aviation, rail, maritime, mass transit, highways/motor carriers, and pipelines, along with intermodal hubs like ports, airports, rail yards, and transit centers. It depends on tightly integrated physical infrastructure and digital systems (dispatch, signaling, industrial control systems, logistics platforms, GPS and communications) to keep commerce, emergency response, and daily mobility functioning. Because transportation is so interconnected, disruptions, cyber incidents, or physical damage in one mode or region can cascade quickly into supply-chain delays, fuel and goods shortages, and reduced access to medical care and public services, making resilience, redundancy, and rapid restoration essential to national security and economic stability.
