• Abstract:
  This report offers the methodology and findings of the updates to the South Dakota Accident Reduction Factors (ARFs) and Severity Reduction Ratios (SRRs). The ARFs and SRRs focused on Roadway Safety Improvement (RSI) projects located in the State of South Dakota. A literature search was conducted at the beginning of the project. The researcher used accident data gathered from RSI projects from 1994 to 2000 to calculate the ARFs and SRRs. The researcher updated the Severity Reduction Ratio formula with the most recent FHWA accident severity values. A benefit/cost analysis was performed on the RSI locations to determine their cost effectiveness. Recommendations were made as to the use of the ARFs, SRRs, and the benefit/cost analysis. The recommendations were based on the results of the SDDOT research project, SD2004-06.
