I'm working on a new transit map aimed at visitors to downtown Chicago. One of the things I'm trying to clarify is how to get out of the train station where you've arrived and find the right bus stop. For a city built on a flat site, Chicago is amazingly three-dimensional, and these need to show walkways through buildings, below streets (even if you haven't changed levels), and above streets. Here are drafts of a couple of the maps. I'm interested in whether folks think these clearly show the different levels and places where you have to change levels.
