BACKGROUND Few studies have looked at how obesity affects injury outcomes among vehicle occupants involved in traffic collisions. OBJECTIVE To estimate the association of obesity with death risk among drivers of passenger vehicles aged ≥16 and to examine effect modification by driver sex, driver seat belt use, vehicle type and collision type. METHODS We conducted a matched-pair cohort study...

BACKGROUND There are reports that the incidence of alcohol-involved crashes has remained stable among fatally injured drivers while drug involvement has increased in recent years. METHODS Data from the Fatality Analysis Reporting System (FARS) from 2010 to 2013 were used to examine drug and alcohol status of drivers (N = 10 864) of 4-wheeled passenger vehicles involved in a fatal crash while ...

We examine the effect of introduction ridehailing in US cities on fatal traffic accidents. The arrival is associated with an approximately 3% increase number accidents, for both vehicle occupants and pedestrians. Consistent increasing road usage, we find that its increases proxies congestion new car registrations. a driver quality channel, accident are concentrated ridehailing-eligible vehicles...

The Driver Behaviour Questionnaire (DBQ) is widely used around the world to investigate driving behaviours. However, it has several different versions extracted from the 50-items Manchester driver behaviour questionnaire for variety of societies. This study aims to calibrate the DBQ for the Iranian driver population and explore their aberrant driver behaviour. In total, 524 participants (325 me...

This paper reports the results of a preliminary analysis of daily fatal crashes in New South Wales, Australia, between July 1975 and December 1986. The analysis unexpectedly uncovered a small but statistically significant decline in crashes coinciding with the introduction of a law lowering the legal blood alcohol concentration (BAC) from .08 to .05 g%. The original aim of the analysis was to d...

A study of fatal traffic crashes in Florida examined contributing factors among crashes in which younger (under age 25) drivers were found to be at fault. A case-based analysis was used to improve the accuracy and completeness of the data from the original crash reports. Results were presented using over-representation factors (ORB), a simplified but statistically significant approach to freque...

Graduated driver licensing (GDL) is a critical policy tool for potentially improving teenage driving while reducing teen accident exposure. While previous studies demonstrated that GDL reduces teenage involvement in fatal crashes, much remains unanswered. We explore the mechanisms through which GDL influences accident rates as well as its long term effectiveness on teen driving. In particular, ...

BACKGROUND Road traffic accidents (RTAs) are an important public health problem and the collection of local information is central to successful accident initiatives in a district. As the local coroner is responsible for investigating accidental deaths, the coroner's inquest files are a potentially useful source of information in developing a district strategy to reduce accidents. METHODS A c...

In this work, the design and analysis of new Level Shifter with Gate Driver for Li-Ion battery charger is proposed for high speed and low area in 180nm CMOS technology. The new proposed level shifter is used to raise the voltage level and significantly reduces transfer delay 1.3ns (transfer delay of conventional level shifter) to 0.15ns with the same input signal. Also, the level shifter with g...
