Transportation Systems Sector
Sector Overview
The nation's
transportation system quickly, safely, and securely moves people and goods
through the country and overseas. The Transportation Systems Sector consists
of seven key subsectors, or modes:
·
Aviation includes aircraft, air traffic control
systems, and approximately 450 commercial airports and 19,000 additional
airports, heliports, and landing strips. This mode includes civil and joint use
military airports, heliports, short takeoff and landing ports, and seaplane
bases.
·
Highway
Infrastructure and Motor Carrier encompasses nearly 4 million miles of roadway, almost 600,000
bridges, and some 400 tunnels in 35 states. Vehicles include automobiles,
motorcycles, trucks carrying hazardous materials, other commercial freight
vehicles, motorcoaches, and school buses.
·
Maritime
Transportation System consists of about
95,000 miles of coastline, 361 ports, 25,000 miles of waterways, 3.4 million
square miles of Exclusive Economic Zone, and intermodal landside connections,
which allow the various modes of transportation to move people and goods to,
from, and on the water.
·
Mass
Transit and Passenger Rail includes
service by buses, rail transit (commuter rail, heavy rail--also known as
subways or metros--and light rail, including trolleys and streetcars),
long-distance rail--namely Amtrak and Alaska Railroad--and other, less common
types of service (cable cars, inclined planes, funiculars, and automated
guideway systems).
·
Pipeline
Systems consist of vast networks
of pipeline that traverse hundreds of thousands of miles throughout the
country, carrying nearly all of the nation's natural gas and about 65 percent
of hazardous liquids, as well as various chemicals. These include approximately
2.2 million miles of natural gas distribution pipelines, about 168,900 miles of
hazardous liquid pipelines, and more than 109 liquefied natural gas processing
and storage facilities.
·
Freight
Rail consists of seven major
carriers, hundreds of smaller railroads, over 140,000 miles of active railroad,
over 1.3 million freight cars, and roughly 20,000 locomotives. Further, over 12,000
trains operate daily. The Department of Defense has designated 30,000 miles of
track and structure as critical to mobilization and resupply of U.S. forces.
·
Postal
and Shipping moves over 574
million messages, products, and financial transactions each day. Postal
and shipping activity is differentiated from general cargo operations by its
focus on letter or flat mail, publications, or small- and medium-size packages
and by service from millions of senders to nearly 152 million destinations.
Sector-Specific Plan
The Transportation Systems Sector-Specific Plan (PDF,
346 pages – 7.61 MB) details how the National Infrastructure Protection Plan
risk management framework is implemented within the context of the unique
characteristics and risk landscape of the sector. Each Sector-Specific Agency
develops a sector-specific plan through a coordinated effort involving its
public and private sector partners. The Postal and Shipping Sector was
consolidated within the Transportation Systems Sector in 2013 under
Presidential Policy Directive 21. The Department of Homeland Security and
the Department of Transportation are designated as the Co-Sector-Specific
Agencies for the Transportation Systems Sector.
