This paper revisits the question of the relationship between rural road geometric characteristics, accident rates and their prediction, using a rigorous non-parametric statistical methodology known as hierarchical tree-based regression. The goal of this paper is twofold: first, it develops a methodology that quantitatively assesses the effects of various highway geometric characteristics on acc...

In recent years, there has been an abundance of research that has used Poisson models and its variants (negative binomial and zero-inflated models) to improve our understanding of the factors that affect accident frequencies on roadway segments. This study explores the application of an alternate method, tobit regression, by viewing vehicle accident rates directly (instead of frequencies) as a ...

The accidents at work of 4482 employees in a car engine machining and assembly plant in south east England were studied retrospectively over a 12 month period. The study population was composed of Asian (22%), white (66%), and West Indian employees (12%). The crude accident rates differed among the groups, the means being Asians 1.58, white 1.23, and West Indians 1.28. There was, however, no co...

Accident rates of heavy truck-tractors are modelled using log-linear methods. The accident data used are a census of truck-tractor involvements in Michigan from May 1987 to April 1988. Travel data used to calculate the rates were produced by a survey of truck-tractors in Michigan covering the same time period. Both the accident and travel data were limited to Michigan-registered tractors operat...

W ith the advent of the automobile as a mode of transportation late in the nineteenth century, a new phenomenon, the motor vehicle acci­ dent, appeared on the American scene. While the motor vehicle was in its early stages of development, the problem was not serious. How­ ever, as the volume of cars on the highways increased, the number of accidents increased also; the problem began to assume g...

The recent series of railway accidents raised questions about the safety of British Railways. We have studied trends in accidents to railway staff over a 33-year period, 1954-86, which time has covered the pre- and post-modernization of the railways, in conjunction with large reductions in both staffing and traffic volume. The Railway Inspectorate, which has the duty of investigating and report...

BACKGROUND The British merchant fleet has expanded in recent years but it is not known whether this expansion has led to proportionate changes in mortality. AIMS To investigate mortality from accidents and injuries in British merchant shipping, to determine whether this has increased in recent years, to compare fatal accident rates across British industries and to review fatal accident rates ...

  Purpose: Cardiopulmonary resuscitation (CPR) is an important step for patient survival inside   and outside the hospital. Therefore, the results of CPR can be effective in modifying the structure   of this operation and in eliminating its shortcomings. The purpose of this study was to evaluate   the success rate of CPR in intensive care unit of an Iran’s Army Air Force hospital in 2012.   Mat...
