Abstract: RCUTs, also known as RCIs, superstreets, or Jturns, are a popular alternative intersection design. RCUTs redirect left-turn and through movements from the minor road into right turns, followed by downstream U-turns to complete the maneuver. There are more than 500 RCUTs in the United States, with safety performance varying across states. Previous studies have reported crash reductions ranging from 20% to 70%. In Mississippi, 16 unsignalized RCUTs were constructed between 2012 and 2021, primarily on high-speed multilane highways. This research evaluates their safety performance using an Empirical Bayes (EB) before-and-after approach.
