This report offers the methodology and findings of the first project to develop Accident Reduction Factors (ARFs) and Severity Reduction Ratios (SRRs) for the state of South Dakota. The ARFs and SRRs of this project focused on Hazard Elimination and Safety (HES) projects located within the state of South Dakota. A literature search for information relating to ARFs was performed at the beginning of the study. Department researchers used project plans and accident data from each of the HES projects, from 1986 to 1994, in developing ARFs and SRRs. The technical panel for SD98-13 developed a Severity Reduction Formula which was used to compute SRRs. A benefit/cost analysis was performed on each project to determine the project's cost effectiveness. Recommendations were made to use the ARFs and SRRs to aid in determining the effectiveness of HES projects. The recommendations were based on the literature review and the results from this project.
