Origami Tessellation: Traffic Plan

This is just a random idea that I had for a square grid tessellation. It's building off of several common shapes and techniques. 

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. .
