Abstract

This study estimated how the presence of an airbag may effect severity indices (SI's) for crashes with roadside objects. HSIS data from Illinois, North Carolina, and Utah were used in the analysis. In summary, airbags reduce the severity index by 10 to 30 percent for point objects, 40 to 50 percent for guardrails, and 10 to 20 percent for other longitudinal barriers.
