Street Network Orientation of Major Cities

This amazing chart by urban planning professor Geoff Boeing examines street network orientation in 100 cities around the world.

Each radial graph on the image represent every street in the given city. The length of the bar from the center represents how many streets in that city run on that compass direction. So a graph that is only blue on the north/south axis and east/west axis means that this city’s layout is a very tight grid. A graph that is all colored means that the given city is a rats nest of streets running in every direction.

Here is another version of the same image, re-sorted from most-ordered/gridded city (Chicago) to most-disordered (Charlotte):
