This paper examines NASS/CDS 1995 to 2001 in order to evaluate rollover crash severity metrics and to recommend additional data elements to assist in determining rollover severity. For belted occupants and unbelted ejected occupants in single vehicle crashes, the number of roof impacts is an appropriate severity indicator. For ejected occupants, the ejection risk generally increases with the nu...

A model of lending is presented where loans are established in matches between banks (lenders) and entrepreneurs (borrowers) who meet in a search process. Projects turn out randomly a quick payoff or a long-term payoff that requires a rollover of the loan. The model generates, under proper parameter conditions, two steady states without or with rollover, and rollover is socially inefficient. Un...

In the roadside safety community, there has been debate over the influence of vehicle and barrier type on rollover rates in traffic barrier crashes. This study investigated rollover rates between sport utility vehicles (SUVs), pickup trucks, and cars in vehicle-traffic barrier crashes and has examined the effect of barrier type on rollover risk for concrete barrier and metal barrier impacts. Th...

Vibrator, as a crucial vehicle of oil and gas exploration, is challenged by the complex terrains. The probability of rollover accident is therefore high in bumpy terrain in which the drivers’ life is seriously threatened. Finite element numerical analysis was used to study the injury of the driver’s head, neck and chest in the rollover accidents of domestic KZ-28 type vibrator on different cond...

Earlier studies by the authors have examined factors that contribute to rollover crash severity. These factors include: (1) belt use, (2) the number of quarter-turns aggregated according to number of vehicle inversions, and (3) the damage severity from planar impacts with fixed and non-fixed objects that occur before or during the rollover. Further research indicated that rollovers with severe ...

Recent analyses have established that 4WD vehicles are aggressive in crashes, causing comparatively more harm than other passenger vehicles when in collision with other road users, and have a high risk of rollover crashes. To assess the safety of these vehicles more completely, this study produced two analyses of risk: firstly, estimates of crash risk and injury rates using NZ data; and, second...

This study investigated the effects of shoe heel height on the rollover characteristics of the biologic ankle-foot system. Ten nondisabled adult female volunteers walked using three pairs of shoes with varying heel heights and at three walking speeds with each pair of shoes. Kinematic and kinetic data needed to calculate the rollover shapes of the ankle-foot systems of the participants were col...

Two different rollover crash scenarios were simulated with the software Madymo. The vehicle kinematics in the numerical simulation were prescribed by the use of sensor signals of real crash tests. The Madymo 50% Hybrid III dummy model as well as the Madymo human model was applied to these simulations and the model kinematics were analysed and compared. Differences in the kinematics of human and...
