I think this is a good idea, but there isn't much in the way of API access or documentation for SFMTA systems. Beyond Nextbus, there is no API to poll for data.

I think this is a good idea, but there isn't much in the way of API access or documentation for SFMTA systems. Beyond Nextbus, there is no API to poll for data. Nearly everything requires a request for information or Sunshine request, where a staff member stops what they are doing, goes to an internal system (Trapeze, for example), does a C&P, removes HR info, and passes it along. That being said, some of the newer SFMTA projects do have a data stream to at least scrape, like road construction schedules, Muni Forward, and Vision Zero collision data. There is a whole lot more data available, most of it released quarterly, I could help get access too as well.
