New option for AATA trip planning
You won't find a link to it on the AATA site but Google maps has added Ann Arbor to the list of cities for which you can get transit directions as well as driving directions. It's also pretty hard to tell by looking at the page that you're there but this seems to be where you start: Google Transit Ann Arbor
Perhaps one reason AATA isn't really promoting this is that it has its own trip planning site. In not-very-extensive testing, each site seems to have its own quirks, but they definitely have advantages over using the printed route maps and timetables. Even experienced transit users can find it a little daunting to figure out a new route with them; for people who are considering taking the bus for the first time, trying to make sense of them can be a big barrier. Any new options that help potential transit users become actual transit users can't hurt efforts to increase ridership.
