I'm not really sure how useful this will end up being, but I was in a proof-of-concept mood yesterday and created a
Transit Options in Near Southeast page, taking advantage of the new and existing live status options for
Metrorail,
Circulator, and
Metrobus. You'll see boxes displaying the next trains at the Navy Yard station, the next Circulator arriving at New Jersey and M (though I'm not sure how handy this one is--aren't there pretty much always buses sitting there?), and the upcoming Metrobuses arriving at New Jersey and M.
There's also links to the live status updates for all the Circulator stops in Near Southeast and all the Metrobuses that run through the neighborhood (including the ones that stop at South Capitol and M). I even added links to the timetables to the two Maryland Transit Authority commuter buses that stop near the Navy Yard.
There's also a lightweight
mobile version, if you're so inclined. The link to the full page is now at the top of the JDLand home page ("Bus/Rail Info") and in the right margin on the interior pages.
UPDATE: Thanks to the idea from commenter JT, you can now also click on the little tiny "M"s (if your eyes are good enough to see them!) on the map at right to get to the transit page.
