Background: Road traffic accidents (RTAs) are the main public health problems in Iran. The seat belts, which are vehicle safety devices, are imperative to reduce the risk of severe injuries and mortality. Objectives: The aim of the study was to evaluate injury patterns, severity and outcome among belted and unbelted car occupants who were injured in car accidents. Patients and Methods: This cro...

Rollover detection and prevention are among the most critical aspects affecting stability safety assessment of heavy vehicles, especially for off-road driving applications. This topic has been studied in past analyzed depth terms vehicle modelling control algorithms design able to prevent rollover risk. However, it still represents a serious problem automotive carmakers due huge counts main cau...

A study pointed out that the delay time of driver's nervous system has a significant effect on roll stability vehicle. However, existing researches vehicle rollover prevention control rarely consider influence driver factors stability. Aiming at this problem, and path tracking strategy considering in loop is proposed to assist different types drivers. It includes supervisory decision layer exec...

The objective of this paper is to develop an analytical framework to representing the ankle-foot kinematics by modelling the foot as a rollover rocker, which cannot only be used as a generic tool for general gait simulation but also allows for case-specific modelling if required. Previously, the rollover models used in gait simulation have often been based on specific functions that have usuall...

Occupant kinematics during rollover inverted impacts has been the subject of significant research. Controlled experiments have utilized complete vehicles, partial vehicles and seat/restraint systems attached to various platforms. The Deformable Occupant Compartment Impact Tester (DOCIT) was developed to incorporate functions similar to previous methods, but has added a roof capable of deforming...

As product life cycles become shortened, companies frequently launch new products and discontinue existing ones. Companies with large and complete product lines do not have the extra resources to extend them, so they must plan successful product rollover schemes that launch new products and discard existing ones simultaneously. In previous studies, new product launch schemes and existing produc...

Using payday-lender administrative data matched to borrower credit attributes from a national credit bureau, I find that borrowers who engage in protracted refinancing (“rollover”) activity have better financial outcomes (measured by changes in credit scores) than consumers whose borrowing is limited to shorter periods. These results are robust to an alternative definition of a “rollover” that ...

Roadside safety barriers are designed to deflect errant vehicles back onto the carriageway, preventing them from encountering potentially dangerous off-road hazards or crossing into the opposing carriageway on dual carriageways. However, there are concerns that SUVs and MPVs, by virtue of their greater mass and height, may not be well catered for by the current design of safety barrier, which i...
