Abstract

National Cooperative Highway Research Program (NCHRP) Report 350 contains recommended test matrices and impact conditions for evaluating the impact performance of roadside safety features. This paper focuses on related issues that may warrant consideration in future updates of these guidelines. Specific areas discussed are, for impact conditions, impact speed, impact angle, energy considerations, accident data, and lateral offset relationship, and for test matrices, terminals/crash cushions (tests 30, 32, 33, and 39), terminals/crash cushions transition, truck mounted attenuators (tests 3-50, 52 and 53), optional tests, and side impact testing.
