Within the framework of a safety measure of the netherlands national traffic safety plan, to stimulate the approach to relative hazardous situations, experiences with the use of a regional traffic accident concentration list in the provinces of friesland and drenthe are presented. Emphasis is laid on the efficiency of such a list for the combined approach in a region. Suggested improvements not yet carried out are presented. The relationship between such a regional list and a national traffic accident concentration list are mentioned.
