Also known as a continuous flow interchange (CFI) or crossover displaced left-turn (XDLT), this signalized intersection type relocates one or more left-turn movements on an approach to the other side of the opposing traffic flow. Signals are placed at crossover intersections upstream of the main intersection and left-turn movements run simultaneously with the through movement, eliminating the need for a left-turn phase for that approach. When analyzing operations or safety of a DLT intersection, the analysis typically includes the core intersection as well as the satellite intersections. See

Figure 10-6

for the basic features and flow patterns of a DLT. This intersection type requires restriction of access within the influence area of the layout. Right-in and right-right access may be permitted but not close to the cross-over areas
