Abstract: This paper describes an investigation of traffic barrier performance in New York State. A one-year sample of all traffic-barrier accidents in the state was obtained from Department of Motor Vehicle files. Field investigations were completed on more than 3000 accidents to identify barrier and roadway features. This information was combined with vehicle and injury data, and accident descriptions. Barrier performance is discussed in terms of several evaluation criteria, including occupant injuries, barrier penetration, and secondary collisions. The effects of several variables are examined, including impact conditions, vehicle size and weight, and highway and barrier parameters.
