RESPONSE
TRANSPORTATION SYSTEMS
• Provide an essential function to
society by moving people and
goods from point “A” to point “B”
• Represent a substantial share of a
country’s GDP (11% for USA.)
TRANSPORTATION SYSTEMS
• Types: Roads, railroads, mass
transit, water-borne and air
transport systems, and
pipelines
• Scales: urban, regional,
national, and international.
ELEMENTS OF
TRANSPORTATION SYSTEMS
• Built infrastructure
• roads, runways,
airports, terminals,
railways, stations,
canals, ports, traffic
control centers,
maintenance and
operation facilities,
pipelines, etc.
• Operations side
• vehicles, traffic
safety and control,
power, communications and
signaling,
maintenance,
transportation
operators, etc.
FEATURES THAT AFFECT
RESILIENCY
Extend over broad geographical
areas
Large number of components that
are subject to either POINT or
AREA failure.
FEATURES THAT AFFECT
RESILIENCY (Continued)
Roadways and railways frequently
follow river valleys (easier and
cheaper to build)
Utilities, including pipelines, often
follow right-of-ways (reduces legal
problems and costs)
FEATURES THAT AFFECT
RESILIENCY (Continued)
Multiple entities have
responsibility for or oversight
of the system
Typically owned by public
entities and publicly funded
Usually self insured
FEATURES THAT AFFECT
RESILIENCY (Continued)
Different modes of transportation are interconnected
They interact with each other
and other elements of a
community’s built environment; hence, the name,
Lifeline systems”.
 HIGHWAY SYSTEMS
Flooding from tropical storms,
hurricanes, and typhoons,
Landslides (rock falls, spreads,
slides, flows)
Earthquakes (ground shaking)
