Daily, plain-language GTFS quality scorecards for small transit agencies: see the current grade, the three things to fix, and why each one matters. GTFS Scorecard is a daily data-quality service for small transit agencies and the program staff, maintainers, and vendors who support them. It publishes dated grades, prioritized fixes, history, program views, practitioner tools, and open data. It does not implement a competing GTFS validator. Correctness findings come from MobilityData's canonical validator.
