-
Warning Response Research
Started in the 1950’sDriven by the shadow of nuclear warIf we sound the sirens, what will people do?Series of studies - tornado, hurricane, flood, explosion, air raid sirens, alien invasionsMajor findings People seek more information People converge on event
-
Warning Response Process

Alternative Responses to Natural and Technological Hazards
Do nothing/ denialConfirm warning/ seek informationEvacuate/ temporary relocationSeek protective shelter/ stay home/ isolationRespiratory protectionDecontaminateSeek medical attentionHelp others
-
Modeling Diffusion of Warning
-
Intelligent Consequence Management
New sensor networks or links to existing sensor networks designed to detect and monitor the threats of concernHigh-speed communications and data exchangeReal-time simulation models running on high-speed machinesFaster than real-time predictive capabilitiesAdvanced decision support tools that can process data and simulation outputs into a format useful to decision-makers
-
ORNL LDRD
Dynamic evacuation modelingUtilize deployable road sensor tape or existing monitorsFirst evacuation model with dynamic traffic assignmentCan update simulations using real time dataLinked to GIS

Major Questions
How will warnings be issued to publics once a bio event is identified?To what degree will human behavior in a bio event be similar to other hazards?Will bio events elicit a different types of human response than observed for other hazards?What are the relevant parameters to model in a bio event?
