| Abstract |
In the study, the Longitudinal Barrier Special Studies (LBSS) file was cleaned for use in examining the real-world performance of longitudinal barriers. Given that impact speeds were mostly missing from the LBSS file, impact speeds were reconstructed for several accidents. An examination of the accuracy of reconstructed impact speeds was also performed using input from three experts in barrier accident reconstruction. Descriptive and statistical analyses were performed to compare one barrier type vs. another in terms of driver injury. Where appropriate, logistical models were developed that utilized impact speed, impact angle, and vehicle curb weight as covariates. Another comparison involved severity of impacts to ends vs. length of need (LON). Nearly 1,200 cases were available for analysis. Two-thirds of the cases involved a LON and one-third involved an end impact. Two-thirds of the cases involved guardrail accidents; the remainder were median barrier accidents. Clinical analysis of barrier performance was also undertaken to learn more about length-of-need segment failures and barrier-ends. |
