The analysis of road accident data was carried out to explore the impact of local factors on the values of accident hazard indicators and to identify some reasons for the territorial diversity in the accident hazard observed in various regions of Poland. In particular, the objective of this work was to find the causative factors and the reasons for the occurrence of excessive numbers of road accidents in some regions and to show the possible ways of reducing this hazard. Within this study, the impact of the demographic factor and of the diversity in road infrastructure and in the numbers of vehicles in specific regions was examined. Based on a relevant and adequate dataset collected, the values of several characteristic indicators were calculated and variations in these data recorded in the years 2010-2016 were shown. The relations between this hazard and the population size, total road length, and total number of vehicles in individual regions were assessed. The territorial distribution of this hazard in Poland was shown, with using special indicators that made it possible to eliminate to a considerable extent the significant influence of the region size on the result of assessment of the accident hazard. The calculation results became a basis for establishing a multidimensional space of hazard indicators in which consideration is given to diverse features of individual regions. This made it possible to select the regions for which the values of the accident hazard indicators were particularly high and low.
