The diverging diamond interchange (DDI), or the double crossover diamond, is a simple yet effective road design that optimizes the mobility and safety of every road user. They are far better than conventional interchanges in many aspects–including effectiveness and cost. However, the appearance of these two is seemingly identical. If you are in the United States, you can see them regularly.
Diverging diamond interchange has efficient management of left turns. Furthermore, drivers can do right turns in a DDI in a way that is similar to when they are making right turns in the conventional diamond interchange.
The difference between the DDIs and standard interchanges is the crossover intersection. By far, it is undeniable the crossover intersections of DDIs are quite intuitive for drivers. Specifically, the crossover allows gentle transition of traffic from the right side of the road to the left side, and then return to the flow again.
