The article discusses selected aspects of the analysis on road accidents data and the possibility of their use in order to create a background for further, more exhaustive study of specific problems of road safety. These problems may result from such analyzes by their breakdown through specific comparisons and drawing appropriate conclusions. Attention was paid to the manner of data presentation and important problem of their systematic collection. In this paper the results of particular analyses as well as selected aspects concerning the causes of road accidents are discussed. Attention was paid to the possibilities of conducting detailed analysis on this research area. Occurrence of road accidents does not have to be connected with relationships directly between motor vehicles, and it seems obvious that the influence of environment should be included. Also an important issue of systematic and consistent data collection about accidents is mentioned.
