Page redirects will work even if the page that is forwarded has category information.
So you can write a page for AATA with content like this:
#REDIRECT [[Ann Arbor Transportation Authority]]
[[Category:Acronyms]]
Which will auto forward the user to the correct explanatory page.
The bonus is you get a nice listing of everything categorized as an acronym (ArborWiki example)

Good find, thanks for the tip. Will use this on the Richmond Wiki.
However for SEO purposes I like direct linking to the page but using the acronym as the anchor text. In your example it would be:
[[Ann Arbor Transportation Authority|AATA]]
