Crashworthiness is the ability of a structure to protect its occupants during an impact. This is commonly tested when investigating the safety of aircraft and vehicles. Depending on the nature of the impact and the vehicle involved, different criteria are used to determine the crashworthiness of the structure. Crashworthiness may be assessed either prospectively, using computer models (e.g., LS-DYNA, MSC Dytran, MADYMO) or experiments, or retrospectively by analyzing crash outcomes. Several criteria are used to assess crashworthiness prospectively, including the deformation patterns of the vehicle structure, the acceleration experienced by the vehicle during an impact, and the probability of injury predicted by human body models. Injury probability is defined using criteria, which are mechanical parameters (e.g., force, acceleration, or deformation) that correlate with injury risk. A common injury criterion is the Head impact criterion (HIC). Crashworthiness is assessed retrospectively by analyzing injury risk in real-world crashes, often using regression or other statistical techniques to control for the myriad of confounders that are present in crashes.
During my two-year tenure as chairman of the Chrysler Safety Leadership Team (1992-1994) I was required to make numerous safety recommendations to upper management. Included in that group was Francois J. Castaing, Executive Vice President of Engineering. At this time Castaing was also Product Executive assigned to all Jeep products and Jeep business planning. In severe injury product litigation (Tenaglia v. Chrysler) the crashworthiness of a Jeep product was examined. During the deposition of March 14, 1996, plaintiff attorney Larry Coben asks Castaing, executive of all Chrysler vehicle engineering, to define the term 'crash-worthiness' for the jury. The relevant Castaing testimony appears on Page 11 of the transcript and beginning at five-minutes-forty-seconds on the attached video: ...
IIHS evaluates a vehicle's crashworthiness with the help of five tests: moderate overlap front, small overlap front, side, roof strength and head restraints & seats. For front crash prevention ratings, the Institute conducts low- and moderate-speed track tests of vehicles with automatic braking systems. The descriptions below explain how each test is conducted and how the results translate into ratings.

On May 13th, 2013 Attorney Todd Tracy sent a 2010 Chevrolet Traverse out to California at an Automotive teting facility to conduct a rollover dolly test. The vehicle was fitted with ATD (crash dummies) test devices. There was one in each of the seven seats in the vehicle. The class is presented as recent information involving crashworthiness aspects as it relates to modern vehicles and their ability to keep us safe in a rollover accident.

The U.S. Federal Railroad Administration (FRA), through its Office of Safety, is engaged in a program to assess overall collision safety for new major high-speed passenger rail corridors. This assessment covered both collision avoidance and collision survivability for one existing and proposed major US high-speed passenger rail corridor. In this research study, the focus was to determine, for a wide range of collision scenarios, the crashworthiness and occupant survivability of the two rail systems.
