Work Accident Analysis with Accident Rates Calculations

Ethnic differences in accident rates at work.

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...

Assessing Heavy - Vehicle Accident Rates for Marginal Cost Calculations

An Analysis of High Accident Rates

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...

A multivariate tobit analysis of highway accident-injury-severity rates.

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...

A Tobit Model of Vehicle Accident Rates

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 ...
