Evidence-Based Highway Safety Strategies: Turning Knowledge into Action Governors Highway Safety Association Annual Meeting Scottsdale, AZ September 9, 2008 Adrian K. Lund, Ph.D. President IIHS vehicle research center IIHS Outside car companies, few facilities in the world are equipped to conduct the range of crash tests and other research the Vehicle Research Center can accommodate. 40 mph frontal offset crash test of Smart Fortwo IIHS Overview Research on turning knowledge into action? – Hope (hypotheses) into policy Dr. Susan Ferguson Dr. Robyn Robertson – Specific examples of research now being conducted to turn hopes into results Emphasize other areas where already we know what works – – Just waiting for the politically astute – or clever – among you to put them into action IIHS IIHS mission is to use research to identify ways to reduce deaths, injuries, and property damage from motor vehicle crashes Focus is on applied research – Define problems – Identify countermeasures – Evaluate countermeasures – Understand why effective countermeasures are not widely used IIHS Funded entirely by U.S. auto insurers The Insurance Institute for Highway Safety is an independent, nonprofit, scientific and educational organization dedicated to reducing the losses — deaths, injuries, and property damage — from crashes on the nation's highways. founded in 1959 The Highway Loss Data Institute shares and supports this mission through scientific studies of insurance data representing the human and economic losses resulting from the ownership and operation of different types of vehicles and by publishing insurance loss results by vehicle make and model. founded in 1972 IIHS Where are we?
