Project overview
The challenge
Accessibility information can be incomplete or hard to evaluate across a transit feed. Agencies and developers need a repeatable way to identify gaps.
Our work
Using the California Transit Data Guidelines, we built web and command-line tools to evaluate accessibility data in GTFS feeds, including wheelchair information, text-to-speech fields, route-color contrast, and station accessibility information. These checks assess the published data; they do not certify the physical accessibility of stops, stations, or vehicles, or the accessibility of an entire website.
The result
Web and command-line reports identify passing and failing checks. We also created a public website showing current accessibility-data issues for more than 40 Bay Area transit agencies, updated daily.
