Crashworthiness is a research area that focuses on designing and optimizing vehicles to minimize the effects of crashes on occupants and ensure they are as safe as possible in the event of a collision. This includes studying and improving the structural integrity of vehicles, their restraints systems (such as seat belts and airbags), and other safety features to reduce the risk of injury and increase the chances of survival for occupants. Crashworthiness research aims to enhance the overall safety and survivability of vehicles in various crash scenarios, including frontal, side, and rear impacts.
