You might also want to at least look at RISA. I know that RISA can do a
"moving" load, of which some of the built-in "moving" loads are for AASHTO
loadings. This would be essentially be similar to doing the influence
lines for the AASHTO.
What I don't recall is if the steel design checks can be done per AASHTO,
which I believe varies slightly in some cases from AISC specifications.
Still worth looking into...good analysis package with really good product
