fuzzy logic is one of the concepts that has created different scientific attitudes by entering into various professional fields nowadays and in some cases has made remarkable effects on the results of the practical researches. however, the existence of stochastic and uncertain situations in risk and accident field, affects the possibility of the forecasting and preventing the occurrence of the ...

Logistic regression was applied to accident-related data collected from traffic police records in order to examine the contribution of several variables to accident severity. A total of 560 subjects involved in serious accidents were sampled. Accident severity (the dependent variable) in this study is a dichotomous variable with two categories, fatal and non-fatal. Therefore, each of the subjec...

Data from the Oxford Record Linkage Study have been used to describe rates of accident repetition for children aged under 5 years. As reflected by hospital admissions, accident rates for children who have already had one accident were approximately twice those of children of the same age and sex who had previously been accident free.

Numerous evaluation studies have reported large accident reductions when road accident blackspots are treated. A critical examination of these studies reveals that many of them do not account for the effects of well known confounding factors, like the regression-to-the-mean effect that is likely to occur at road accident blackspots. This paper shows that the more confounding factors evaluation ...

Log-linear modeling is advanced as a procedure to identify factors that underlie the relative frequency of occurrence of various accident characteristics, such as accident type, location, and severity. The method is centered on the estimation of saturated log-linear models for pairs of accident variables and determination of indices of association between categories of the variables. Using data...

INTRODUCTION Models of external exposure for the population living in contaminated areas developed before the Chernobyl accident (1) were improved by taking into account post-Chernobyl data in Russia (2) and in Ukraine (3). Later, within the framework of the joint international EU-FSU research project JSP-5 «Pathway analysis and dose distributions», a general model (JSP-5 model) applicable to t...
