Abstract:

Diverging Diamond Interchanges (DDIs) are characterized by crossover intersections at the ramp termini where cross-street traffic crosses over to the left-hand side of the roadway between the ramps to allow unopposed left turns to and from the ramps. DDIs are used in situations with grade-separated interchanges.
