Intersection

Usually we think of an intersection as a simple square where two streets cross one another controlled by stop signs or traffic lights. That is, unless you live in a European country where you may think primarily in terms of roundabouts. In fact, there is a wide variety of intersection shapes based primarily on circular or angular geometries scattered throughout the world.

Regardless of geometry and signaling rules, the essential characteristic of an Intersection is that one or more Roads meet at some location where traffic from one of the Roads can transfer to a different Road. It is the Roads that are intersecting one another via some usually well defined system.

It would be folly to attempt to enumerate or classify every possible arrangement or geometry of intersecting roads as there would be quite a large number classifications necessary to be exhaustive. Rather we can try to identify a handful of building blocks that can be assembled in various ways to account for all possible, or at least likely, intersections.
