Is your feature request related to a problem? Please describe.
An a transit accessibility activist, I'd love a way to expose agencies to the accessibility information that is contained in their GTFS.
Describe the solution you'd like
Make a site similar either to https://accessibility.bayareatransit.org/ or add to our report like the output from https://validator.blinktag.com/

Describe alternatives you've considered
Open to ideas.

Additionally we may be able to make a query on RT accessibility metrics, whether they are a part of the GTFS or not.
