If you ride the Circulator, a new map tool for the web and smartphones by Jim Blakeslee from Geocentric can help you track buses and get arrival predictions.

The home page shows each line, including which ones are seasonally inactive (the Mall loop, right now). Clicking on any individual line gives you a screen with a link to a live map for that line, or the real-time predictions for every stop in one or the other direction.

There’s also a full map (shown above), which gives a nice overall view of the system. For most individual riders’ needs when taking a specific trip, the individual line pages and maps will most likely be the most useful.
