Evaluating the Performance of Longitudinal Barriers on Curved, Superelevated Roadway Sections

The objectives of this research were to (1) evaluate the crash performance of standard longitudinal barriers installed on superelevated, curved roadways; (2) determine if the curvature and superelevation details used by the state DOTs degrade the performance of the barriers to the extent that they will no longer meet the crash test criteria for MASH TL-3; and (3) develop a plan for possible future research to study barrier modifications, changes to roadway geometrics, or both, in response to any identified problems.
