Abstract

The second part of the paper elaborates further on the quantification of road safety. It explains the issue of confounding variables, in particular regression-to-the-mean, as well as difference between recorded and expected accidents. The solution lies in the modelling of expected accident frequency, using traffic volume and other characteristics as explanatory variables. Accident prediction model is to be applied by empirical Bayes method. The paper also suggests possible use in the Czech environment together with the current transition of the European Directive on road infrastructure safety management.
