• Abstract:
  The design of highway curves has significant impact on traffic safety. More than 25% of fatal crashes in the United States occur on horizontal curves, and the crash rate for curves is approximately three times higher than other highway sections. This research focuses on a detailed analysis of curves where vehicle crashes occur in South Carolina. Eight years of crash data and an inventory of circular curves are analyzed to identify trends and the effectiveness of countermeasures. The research achieved several objectives including identifying potential locations of compliance issues related to curve signage and also identifying curve locations of highest crash frequency that can benefit from potential countermeasures.
