Note: Some of the popular press for this paper was somewhat misleading, unintentionally. For instance, the New Scientist article begins with the question "Say you are in a hurry to catch a flight. Should you take the moving walkway or bypass it?". My article has exactly nothing to say about this question. My article only discusses the possible behavior of people not in a hurry. On the other hand, Seth Young's Ph.D. thesis addresses some effects of congestion on moving walkways, and might be relevant in this context.
