BACKGROUND In Japan, introduction of severe drunk-driving penalties and a lower blood alcohol concentration (BAC) limit in June 2002 was followed by a substantial reduction in fatal alcohol-related crashes. However, previous research suggests that this reduction started before the legal amendments. The causes of the decrease have not been studied in detail. METHODS Monthly police data on fata...

Several studies have shown that European police crash reports provide different detail degrees of work zone crash-related data. In this sense, the present study aims to verify possibility identifying significant risk factors involved in occurrence road crashes with casualties, based on official data usually available, through a descriptive, binary logistic, and probit regression statistical ana...

Road crash injuries have emerged as a significant public health issue in many low and middle-income countries recent years. In India, motorized two-wheelers comprise 70% of the vehicle population are considered most vulnerable road users. injury is common among young-aged leading to premature deaths. It essential understand risky riding behaviors develop accurate, evidence-based risk reduction ...

The association of helmet use with death in a motorcycle crash can be estimated using matched-pair cohort methods. By estimating effects among naturally matched pairs on the same motorcycle, one can account for potential confounding by motorcycle characteristics, crash characteristics, and other factors that may influence the outcome. The authors used Fatality Analysis Reporting System data, fr...

Oblique impacts of the helmet against ground are most frequent scenarios in real-world motorcycle crashes. The combination two factors that largely affect results oblique impact tests discussed this work. This study aims to quantify effect friction at interface between headform and interior a different magnitudes tangential velocity. helmeted headform, with low high surface was dropped three an...
