road accident severity may be influenced by a number of various systematic causal factors. the weather and road accidents have a close relationship with each other and a number of methods have been proposed for measuring the risk of a road accident with rainy, foggy, and snowy weather and high winds. recent studies indicate that road collision rates increase during precipitation. the weather wa...
OBJECTIVES To investigate the relation between out of hours activity of general practice and accident and emergency services with deprivation and distance from accident and emergency department. DESIGN Six month longitudinal study. SETTING Six general practices and the sole accident and emergency department in Nottingham. SUBJECTS 4745 out of hours contacts generated by 45,182 patients fr...
Children's fear of a car accident occurring to parents or themselves has been used as a concrete example to illustrate one of the symptoms of anxiety disorders such as separation anxiety and generalized anxiety. However, its usage across countries may be questionable where the prevalence of this specific type of injury differs. This cross-sectional study compares samples from seven diverse Euro...
THIS report presents a graphic expression of the accident-volume relation at divided highway intersections. The expression was produced by averaging the past accident experience at 150 intersections. A total of 1, 811 accidents was tabulated in developing the chart. Uses of the chart include: (1) estimating the probable number of accidents which wil l occur in a future period and (2) correcting...
To examine the relationship of ramp design to truck accident rates, this paper presents an analysis of truck accidents in Washington State, plus a comparison to limited data from Colorado and California. We group freeway truck accidents by ramp type, accident type, and by four conflict areas of each merge or diverge ramp. We then compare these groups on the basis of truck accidents per location...
Relatively recent research has illustrated the potential that tobit regression has in studying factors that affect vehicle accident rates (accidents per distance traveled) on specific roadway segments. Tobit regression has been used because accident rates on specific roadway segments are continuous data that are left-censored at zero (they are censored because accidents may not be observed on a...

Background: Safety of contractors is one of the key safety challenges at construction. Safety training, as an essential prerequisite for achieving safety qualification certificates by contractors, could decrease accident rates in the construction. This study aims to evaluate the effectiveness of training construction contractors in safety issues in minimizing occupational accidents in a five-ye...
Traffic accidents are one of the leading causes of fatalities in the world. An important indicator of survival rates after an accident is the time between the accident and when emergency medical personnel are dispatched to the scene. Eliminating the time between when an accident occurs and when first responders are dispatched to the scene decreases mortality rates by 6%.. By combining smart pho...
