Several years ago I saw a list of unusual words and definitions. 
Included was a word that represented the act of walking through the
maze set up to manage a queue (such as at an amusement park) to get
from point A to point B, even though there are no people in the queue.
 I thought it was interesting that there was a word for that, but I've
never been able to remember what it was and it has nagged me ever
since.  What is the word?

You need to look in queuing theory - I did a quick check but can't do
indepth research for this question so all I know are some equations
with symbols for what you are referring to. Good luck.

Thanks! I looked into queuing theory briefly.  Very interesting, but
it seems to apply more to communications and/or computing.  I'm not
sure if the word I'm looking for applies to queuing in this general
sense or only to queuing by people.
