Improved safety: DDIs have been shown to reduce the number of potential conflict points for drivers, which can lead to fewer accidents and injuries.
Better traffic flow: DDIs can improve the efficiency of left turns, which can reduce congestion and delay for drivers.
More efficient use of space: Because DDIs eliminate the need for dedicated left-turn lanes and traffic signals, they can be a more compact and space-efficient design for intersections.
Lower construction costs: DDIs can be less expensive to build than traditional interchanges, which may require more land and more complex engineering.
