Subway Maps

After the discussion of subway maps in class on Sunday I have been thinking about my own experience with them around the world. I don't travel as much as he does, but my boss is out of the office at least 2 weeks out of every month, if not 3. I sometimes have to help guide him through these new cities using their subways. Although the maps are similar (almost all have color coded lines) some can be really confusing just because they offer more stops than DC, thus crowding the map. Below are some examples.

Washington, D.C.

Paris, France
Vienna, Austria
Moscow, Russia
