This report summarizes the analysis procedures and concepts used by the highway research community to design roadside safety appurtenances. The concepts of momentum, kinetic energy and work are presented. Applications to the design of impact attenuators, breakaway hardware, and longitudinal barriers are discussed. The objective of the report is to present the state of the practice in applying mechanics to the design of roadside safety appurtenances.
This report documents the full-scale side impact test of a 1980 Plymouth Champ impacting into a breakaway luminaire support. The impact speed was 30 m...
