The federal highway administration and the university of north carolina highway safety research center have acquired state data for a new highway safety data base - the highway safety information system (hsis). Five states have been included in the hsis. The data files are described as well as the data file processing, and the hsis data guide book. Hsis provides the flexibility to analyze a large number of safety problems, ranging from basic problem identification issues to multivariate modeling efforts to predict future accidents from roadway characteristics and traffic factors. A computerized multi-state data base of accident roadway inventory and traffic information, the hsis is user friendly in terms of formating, and flexible in terms of the numerous ways in which its files can be manipulated andmerged for a specific analysis.
