What We Do
TSA's Office of Security Policy and Industry Engagement leads the unified national effort to protect and secure our nation's intermodal transportation systems. We will ensure the safe movement of passengers and promote the free flow of commerce by building a resilient, robust, and sustainable network with our public and private sector partners.
Transportation Systems Sector-Specific Plan
The Transportation Systems Sector—a sector that comprises all modes of transportation (Aviation, Maritime, Mass Transit, Highway, Freight Rail, and Pipeline)—is a vast, open, interdependent networked system that moves millions of passengers and millions of tons of goods.
The transportation network is critical to the Nation's way of life and economic vitality.
Ensuring its security is the mission charged to all sector partners, including government (Federal, State, regional, local, and tribal) and private industry stakeholders.
Every day, the transportation network connects cities, manufacturers, and retailers, moving large volumes of goods and individuals through a complex network of approximately 4 million miles of roadways, more than 140,000 miles of active rail, 600,000 bridges and tunnels, more than 350 maritime ports, hundreds of thousands of pipeline, nearly 30 million trips using mass transit and passenger rail, and more than 450 U.S. commercial airports.
