STRATEGIES FOR BECOMING DISASTER RESILIENT

DURING 2013

PART 4: MAKE CRITICAL INFRASTRUCTURE

DISASTER RESILIENT

STRATEGY: “CONCENTRATE YOUR POLITICAL AND TECHNICAL RESOURCES ON ACHIEVING ONE

BIG OBJECTIVE -- SUCH AS DISASTER RESILIENT

TRANSPORTATION SYSTEMS”

WHAT HISTORY TEACHES WHAT HISTORY TEACHES

• THE FRAGILITY OF A CITY’S LIFELINES (I.E, INFRASTRUCTURE) WILL PREVENT THE CITY FROM BECOMING DISASTER RESILIENT.

• THE FRAGILITY OF A CITY’S LIFELINES (I.E, INFRASTRUCTURE) WILL PREVENT THE CITY FROM BECOMING DISASTER RESILIENT.

LOSS OF FUNCTION OF A TRANSPORTATION SYSTEM

CAN PARALYZE LOCAL, REGIONAL, AND

INTERNATIONAL EMERGENCY RESPONSE

TRANSPORTATION SYSTEMS

• Provide an essential functionessential function to society by moving people and goods from point “A” to point “B”

• Represent a substantial share of a substantial share of a country’s GDPcountry’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 infrastructureBuilt infrastructure• roads, runways,

airports, terminals, railways, stations, canals, ports, traffic control centers, maintenance and operation facilities, pipelines, etc.

• Operations sideOperations side

• vehicles, traffic safety and control, power, commun-ications and signaling, maintenance, transportation operators, etc.

FEATURES THAT AFFECT RESILIENCY

They extend over broad geographical areas

They have large numbers of components that are subject to either POINT or AREA failures.

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 trans-portation interact with each other and other elements of the city’s built environment (hence, the name, Lifeline Systems”).
