Traffic accidents are among the most frequently analysed negative aspects of transport, and tend to concentrate in certain locations, or road sections. Tools of spatial analysis applied to localized data on traffic accidents allow a quick location of specific segments and intersections with an above-average incidence of traffic accidents. However, traffic accidents are a specific type of point data mostly due to the limited space in which they occur. For this reason it was necessary to use an adjusted version of the traditional methods for the assessment of their spatial distribution. The paper presents selected approaches for evaluating the spatial distribution of traffic accidents in the Czech Republic for the period 2009 to 2013. Road sections have not been completely analysed, but the network is divided separately for road sections and for intersections. Subsequently, the most problematic road sections and intersections were identified using the City of Ostrava as an example. Traffic accidents are also assessed in relation to the volume of traffic for elimination of causality between the traffic volume and intensity of traffic accidents. The specific segments with increased accident rates without the influence of traffic volume were also identified.
