background: injuries and deaths from road traffic crashes are one of the main public health problems throughout the world. this study aimed to identify determinants of fatality traffic accident in iran for the twenty-span year from 1991 to 2011. methods: a time series analysis (1991-2011) was used to examine the effects of some of the key explanatory factors (gdp per capita, number of doctors p...

The results of an extensive literature review of the safety performances of lowand intermediate-traffic-volume, two-lane rural highways are presented. The effects on traffic safety, as measured by accident rates, of pavement width, radius of curve/degree of curve, gradient, sight distance, traffic volume, and design speed on curved sections of two-lane rural highways are covered. The following ...

islamic republic of iran, considering specified guidelines in the horizon of the perspective, as pays attention to annually reducing the maximum number of traffic deaths, tries to minimize the rate of traffic fatalities until 2025 horizon. in order to reduce traffic injuries, iranian traffic police ,through preparing resources, inter-organizational coordinations, using modern technologies, usin...

This study aims to evaluate the impact of pavement physical characteristics on the frequency of single-vehicle run-off-road (ROR) crashes in two-lane separated rural highways. In order to achieve this goal and to introduce the most accurate crash prediction model (CPM), authors have tried to develop generalized linear models, including the Poisson regression (PR), negative binomial regression (...

In-depth studies of behavioural factors in road accidents using conventional methods are often inconclusive and costly. In a series of studies exploring alternative approaches, 200 cross-flow junction road accidents were sampled from the files of Nottinghamshire Constabulary, UK, coded for computer analysis using a specially devised Traffic Related Action Analysis Language, and then examined us...

The aims of this study were: i) to analyze age-related declines in swimming, cycling, and running performances for road-based and off-road triathlons, and ii) to compare age-related changes in these three disciplines between road-based and off-road triathlons. Swimming, cycling, running and total time performances of the top 5 males between 20 and 70 years of age (in 5 year intervals) were anal...

We evaluated the road traffic accidents and drinking habits in all 47 prefectures of Japan by ecological study. Data on traffic accidents were obtained from Ministry of Internal Affairs and Communications, Japan. Drinking habits were also obtained from Ministry of Health Labour and Welfare and The General Insurance Association of Japan. The effect of drinking on road traffic accidents was evalu...

Road traffic accidents are a major cause of premature death and disabilities. Every year the lives of almost 1.24 million people are cut short as a result of a road traffic crash. Between 20 to 50 million more people suffer non-fatal injuries, with many incurring a disability as a result of their injury. Road traffic injuries cause considerable economic losses to victims, their families, and to...
