Abstract
A survey concerning international harmonisation of accident reporting was carried out. The items of investigation were: whether an international computer file on fatal and nonfatal accidents would contribute to understanding of traffic safety and in research on human factors, accident causation and in determining dangerous sections in the road network; what should be sources of data for the files;-which are the most important variables for both fatal and non-fatal-accident-files. Results of the survey are presented in the shape of tables.
