“…While this study illustrates the potential for serious injuries resulting from collisions with reversing cars, the study cohort was limited to those patients admitted to the department of pediatric surgery and therefore prevents the extrapolation of these findings to the general population. (Mayr et al, 2001) With a better understanding of injury patterns resulting from collisions with reversing vehicles and their severity, clinicians including rescue workers and emergency department personnel will be better prepared to quickly triage patients without underestimation of injuries, ultimately improving care (Davidson et al, 2014;Mckay, 2005;Stefanopoulos et al, 2003).…”

“…The passenger compartment deformation and the driver transmitted acceleration are significant factors affecting occupants' injuries and consequently the appropriate triage. It would be particularly useful to have the type of the cars and height of the struck truck under-ride guard, allowing the hospital to organize the rescue teams, plan triage in advance and provide the emergency medical personnel with all necessary information before their arrival at the scene of the accident [15].…”

In car/large truck collisions, the size, weight, and stiffness mismatch results in a much larger structural deformation of the car compared to that of the truck, and larger potential for car occupants injuries. This is further aggravated when the passenger vehicle trends beneath the rear or side of the taller truck. In the US, under-ride guards are required only for the rears of large trucks, although the review of fatal truck-car crashes in the NCSS/CDS indicates that fatal underride crashes involving the sides of large trucks are almost as common as fatal rear under-ride crashes. A methodology using validated finite element models of a passenger car and a truck is utilized in this study to quantify the influence of a side guard attached to a large truck in reducing the intrusion of the car and thus reducing the injury sustained by the occupants of a car in a side crash. A formulation is proposed based on a normalized passenger compartment intrusion and its relation to the occupant injury potential. The transmitted deceleration severity and the occupant compartment intrusion are evaluated for the car impacting a rigid under-ride guard. A NHTSA under-ride test is simulated first for model validation. Once model validation is conducted for a specific guard design, further simulations are conducted at the speed range of 30 to 50 mph and for 90 and 45-degree impact angles. The results from a parametric study are used to identify the critical guard height resulting in severe cabin deceleration and compartment intrusion of the small car. This study quantifies the vulnerability of car occupants in truck side under-ride crashes and the effectiveness of side guard at different ground heights in reducing the injury potential to car occupants.

“…Intrusion of the occupant compartment has been related to occupant injury (Coimbra et al 2008;Conroy et al 2008;Stefanopoulos et al 2003). Blum et al (2008) suggested that the front stiffness of vehicles should be increased to reduce intrusion; however, there is a need to balance vehicle structures for compatibility in vehicle-to-vehicle collisions.…”
