TITLE: Exceptional books on real world applications of graph theory.
QUESTION [27 upvotes]: What are some exceptional graph theory books geared explicitly towards real-world applications?

I would be interested in both general books on the subject (essentially surveys of applied graph theory as a discipline) as well as books about specific applications.  
One may assume up to a year-ish of graph theoretic background.  I am not looking for an introductory graph theory book, nor am I interested in pure graph theory books containing only a few canonical applications (e.g. Bondy & Murty's GTWA).  The book should contain as much exposition connecting the mathematics to the real world as possible, as well as exercises and concrete examples related to applications themselves (e.g. "design a traffic network given the following constraints").
Please mention in your answer what the book does well which sets it apart from others, e.g. "Book X has a great section on graph theory in computational geometry."

REPLY [2 votes]: I would like to mention another nice book about the applications of graph theory, which though I don't think it has all of the virtues of Fred Roberts' book Graph Theory and its Applications to Society, already mentioned, is none-the-less worth a look. The book is: Applications of Graph Theory, editors, Robin Wilson and Lowell Beineke. The book was published by Academic Press in 1979. Its age makes it somewhat "dated" but it still has some rather nice things. Chapters include Graph Theory and Communications Networks (definitely dated), Graph Theory and Electrical Networks, Chemical Applications of Graph Theory, Graph Theory and Operations Research, Graph Theory and Geography, Graph Theory and the Social Sciences (written by Fred Roberts), Architectural Applications of Graph Theory, Graph Theory and Lingistics, etc. (There are total of 13 independent chapters.)
