Hi Max, thanks for reaching out. Sorry for the delayed response — this autumn we changed our internal process for responding to inquiries like this (including onboarding a new team member), and we're now getting up to speed.
There may be some of the data you're looking for in the
MBTA Open Data Portal, but I think your best bet would be to reach out to the Office of Performance Management and Innovation (they own this data) at
op...@mbta.com.
For context,
deve...@mbta.com reaches the T's Transit Data (aka Realtime) team. We manage the T's v3 API and GTFS data, which contains forward-looking, rider-facing schedule and operations information. For performance metrics, or anything historical really, that falls in the realm of OPMI.
I hope that's helpful! If you have more questions about this data source wayfinding, we'll do our best to help.
Warmly,
Developer@MBTA
