R60 / Generalization

Intersection Entrance Lane is an Angular Intersection Entrance Lane or Circular Intersection Entrance Lane

---

In an Angular Intersection, the incoming lanes connect to exit lanes elsewhere in the intersection. But in a Circular Intersection the incoming lanes connect to lanes in an interior, circular Road Segment before leading out of the intersection. This distinction then, is necessary since it allows us to specify the different kinds of pathways through the intersection.
