What is the main advantage of using roundabouts in traffic engineering?

Step 1: Understand what a roundabout is. A roundabout is a circular intersection where traffic flows in one direction around a central island.
Step 2: Learn about conflict points. Conflict points are places where vehicles might collide, such as where cars cross paths.
Step 3: Realize that roundabouts reduce conflict points. In a roundabout, cars do not cross paths as much as they do in traditional intersections.
Step 4: Know that fewer conflict points mean fewer chances for accidents. This makes roundabouts safer for drivers, cyclists, and pedestrians.
Step 5: Understand that roundabouts also help to keep traffic moving smoothly, which can reduce frustration and delays.
