The Automobile Technique Research Association at Frankfurt, the Institute for Forensic Medicine at Mainz, the Federal Highway Research Institute at Bergisch-Gladbach, and the German Workman's Compensation at St. Augustin have completed a common research project dealing with injury costs due to automobile accidents. The data for this social cost analysis was based on costs for administrative expenses, medical treatment, rehabilitation measures, social security payment, and loss of income which were all paid by Workman's compensation for single, well-documented injuries to the working population in West Germany (15 to 65 years old). The data base used included 15,407 injured and 1,026 fatal road accident victims. Tables are presented which show the costs associated with various injury levels. The result is an injury cost scale (ICS) which might be a base for establishing priorities of safety measures. The ICS has to be seen as supplemental to the AIS.
