Abstract:

This paper presents a modified spatial statistical method for identifying road accident hot spots. Our suggested method is based on the Getis-Ord G* index. It differs from the standard method, because in addition to the number of accidents and their consequences, we also consider traffic at the locations of these accidents. The method was tested on the Slovene motorway network. The results are presented with and without considering traffic volumes and are compared with both Kernel density method and Anselin-Moran local index method.
