$600M/year in trucking costs, 150K gallons of fuel/day
 Disaster Mitigation (natural and otherwise)
 $100B-$200B loss in “Big One”, 5K to 10K deaths
 Monitor buildings, bridges, lifeline systems to assess damage after disaster
 Provide efficient, personalized responses
 Must function at maximum performance under very difficult circumstances
Initial CITRIS Applications (2)
