Predicting Occupant Injury with Vehicle-Based Injury Criteria in Roadside Crashes
This dissertation presents the results of a research effort aimed at improving the current occupant injury criteria typically used to assess occupant injury risk in crashes involving roadside hardware such as guardrail. These metrics attempt to derive the risk of injury based solely on the response …

Applications of Event Data Recorder Derived Crash Severity Metrics to Injury Prevention
… occupant risk assessment methods in MASH is the flail space model (FSM), which was introduced in 1981 and models an occupant as an unrestrained point mass. The FSM is comprised of two crash severity metrics that can be calculated using acceleration data from the test vehicle. Each metric is …
