A cheat sheet for Bay Area 511 GTFS-rt feeds.

511.org in the (California) Bay Area provides GTFS and GTFS-Realtime for many of the agencies in the region, including VTA, Caltrain, SF Muni, AC Transit, and a whole lot more.

The docs are available here, but I find the PDF a little dense (and there are some peculiarities), so this is a cheat sheet.

First you need a token sent to your email address.

The first note: API parameters are inconsistent. “Operator ID” and “agency” are used interchangeably to request a particular agency’s feed. A complete list is listed at the foot of this post.

Static GTFS are available at: http://api.511.org/transit/datafeeds?api_key=…&operator_id=SC
NOTE: the GTFS-rt feeds match *these* GTFS files, and are not guaranteed to work with the agency’s original GTFS feed.
