From page 1...
... The safety performance of roadside features is evaluated primarily through full-scale crash testing. The purpose of this testing is to observe and evaluate the performance of safety features under impact conditions that are either similar or more severe than those associated with real-world crashes resulting in serious injuries and fatalities.
From page 2...
... The first objective pertains to the collection of detailed information on serious injury and fatal crashes involving roadside features and safety devices. The data were then analyzed to identify the vehicle types, impact conditions, and site characteristics associated with these crashes.
From page 3...
