Mary Aitken, Professor of Pediatrics with the Injury Prevention Center, Arkansas Children's Hospital, University of Arkansas for Medical Sciences, presented this at CPSC's ATV Safety Summit Oct. 12, 2012. Education for parents and youth riders of all-terrain vehicles (ATVs) has focused on increasing rider use of helmets and other safety equipment, along with reducing other risky behaviors on the vehicles (passengers, road use). Recent focus group and survey data collected by the University of Arkansas for Medical Sciences ATV research group has led to educational material that is clearer and more practical. Users requested information that demonstrated consequences of risky ATV use and targeted both parents and youth riders. The focus group data also indicated that many users have a very inaccurate perception of ATV risk and stability, thereby reducing the perceived need for use of personal safety equipment. We are therefore working with engineers to develop validated computer models of ATVs to simulate performance with child riders and passengers. Recent speed, inclination and surface simulation models are compelling regarding risk to child riders and riders with passengers, showing ejection and ATV instability even at low speeds (10 mph) in some scenarios. When fully validated, these models may inform educational interventions to provide users with more realistic ATV safety images and motivate individual behavior change. The computer simulations can also highlight where ATV stability and performance may be improved.
