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 ...

Background A void in real-world rollover data compilation was fi lled in 2002 with the release of “Characteristics of Fatal Rollover Crashes” (DOT HS 809 438.) Using the Fatality Analysis Reporting System (FARS), DOT HS 809 438 examined an important segment of the rollover population. It was shown in the referenced report that, generally, those without restraint and subject to ejection are the ...

The analysis updates and expands previous research in which rollover critical events were classified based on a detailed review of approximately 500 police-reported single-vehicle rollover crashes of ESC-equipped vehicles. In order to compare the rollover performance of vehicles with and without ESC for the present study, an additional sample of more than 300 police reports on non-ESC single-ve...

Rollover crashes (ROCs) are responsible for almost a third of all highway vehicle occupant fatalities. Although ROCs are common and serious mechanism of injury, ROCs are under-reported. To analyze the causes, mechanism, impact and prevention of ROCs, we reviewed the literature between 1984 and 2013. By utilizing the search engines PubMed, MEDLINE and EMBASE by using key words "ROCs" "Ejection" ...

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...

Rollover is not the most common type of accident, but the consequences may be serious. Understanding of the injury mechanisms during the complex rollover movement is limited and requires further investigation. ln-depth investigations of 21 Volvo cars involved in rollover crashes were analysed with regards to cause and outcome. Detailed information was examined about the crash scenario, the road...

Motor vehicle crashes are the second leading cause of death for on-duty firefighters. Firetruck crashes, occurring at a rate of approximately 30,000 crashes per year, have potentially dire consequences for the vehicle occupants and for the community if the firetruck was traveling to provide emergency services. Data from the United States Fire Administration and the National Highway Traffic Safe...

Rollover risk for passenger vehicles is studied using data from six states. The metric that is used is the number of rollovers per single vehicle accident. The analysis is performed with logistic regression and relevant factors such as weather and driver age are controlled for in the model. The use of categorical analysis permits the data to be used on the observation level, preventing the loss...

Earlier studies by the authors have proposed separating rollover crashes according to belt use, ejection status, and single vs. multiple harmful events. These different classifications were associated with differences that could substantially alter the risk of serious injury. For each classification, metrics to characterize rollover severity were presented. For most single vehicle crashes, the ...
