Projections, Transit maps

map from projections project
I've been reading a book about the graphic design of urban rail and subway system maps. There was a gas shortage so all the libraries were closed one weekend, so I had to go to the bookstore, and I saw it and thought wow, how interesting.

Anyway, it's totally counterintuitive. The less accurate and topographical these maps become, the clearer. The book talks about 45 degree angles a lot. all the angles in a particular subway schematic might be only 45 degrees or 90 degrees. This is of course very different from the actual angles in real life.

I particularly like the Chicago one. Here's a copy.

incidentally, when I googled chicago mta, I found a link to the image which was left by its own designer. wow! His words are here on cartotalk:
