Resumen
Roundabout is a popular and safe type of road intersection, which has become widely used around the world, including Central European countries. To conduct statistical comparative study of traffic safety on roundabouts, accident prediction models (safety performance functions) have to be developed. With this aim accident, traffic and geometry data for samples of rural roundabouts in four Central European countries (Czech Republic, Hungary, Poland, Slovakia) were collected and used in statistical modelling, using state-of-the-art generalized linear modelling framework. Both individual and combined models were developed, which enabled insight into relationships between explanatory variables and accidents, as well as comparison with models from international studies. In the end study limitations are summarized and further improvements outlined.
