The crash performance of roadside safety hardware, such as guardrails, is typically evaluated using full-scale crash tests with vehicles striking the device in representative worst-case impact scenarios. Each test is evaluated based on vehicle response, device response, and potential for injury to vehicle occupants.

NCHRP Research Report 1095: Evaluation and Comparison of Roadside Crash Injury Metrics, a pre-publication draft from TRB's National Cooperative Highway Research Program, evaluates existing roadside crash injury metrics and proposes enhanced crash injury metrics that better reflect the occupant characteristics and vehicle fleet of the 2020s.
