Origami Tessellation: Traffic Plan
There are some octagons, some squares and some two way arrows. This kind of tess has a lot of flexibility though. You can fold the overlaps in any number of different variations.
Corners/points are also easy to switch between. You can have them stick out or you can tuck them in. How you choose to arrange these variables determines your finished pattern.
I find square grid patterns, for the most part, much easier to fold, than triangle grid based designs. The results though, are no less impressive. .
