About RCUT intersections
Used on high-speed, rural, four-lane divided highways, a Restricted Crossing U-Turn (RCUT) is a non-traditional intersection that can ease traffic movements and enhance safety. In an RCUT, side-street (minor cross street) traffic is prohibited from turning left or traveling straight through the mainline intersection. Instead, motorists on the side street will turn right onto the mainline and do a legal U-turn at a nearby crossover. In addition to allowing for a more efficient movement of traffic, RCUT intersections reduce the total number of conflict points, thereby limiting collision opportunities and, most typically, the severity of such collisions.
Benefits of RCUT intersections
Also known as J-turns, RCUT crossings are cost-effective measures that reduce the number of vehicle-vehicle conflict points, reduce the number of turning and angle crashes, and simplify driver decisions. In comparison to signalized intersections and interchanges, construction and maintenance of RCUTs are less costly, easier to maintain and provide a more efficient movement of traffic on the mainline route.
As a proven countermeasure, RCUTs have shown to reduce injury crashes by more than 40% and fatal crashes are reduced by 70% compared to traditional intersections. The safety benefit of the RCUT is that the number of conflict points at the intersection is reduced from 32 to 16.
