Grade C · 74.3 / 100

What this grade measures
The quality of the schedule data in the feed scored here for trip-planning apps: whether riders using Google Maps, Apple Maps, or Transit see current, correct, and complete information. It measures the data feed, not service quality or operations.
Progress this period
No newly cleared items this period. The score and trend above reflect where the feed stands today.
What needs attention next
Three improvements, in priority order, each sized so the board can see what it is approving:
Add feed_info.txt with feed_start_date and feed_end_date to your export.
feed_info.txt is missing its start/end dates (the file itself is absent) Apps and this scorecard can't warn anyone before the feed goes stale without stated validity dates.
Estimated effort: Two fields, set once in export settings.
Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.
1741 of 4924 stops don't say whether a wheelchair user can board there. Riders who use wheelchairs can't plan a trip when accessibility is marked 'unknown'; apps show no information at all.
Estimated effort: A column in stops.txt; your scheduling software likely has it.
Set timepoint=1 on stops that are real time checks and 0 on the rest. If every published time is a scheduled one, mark them all 1.
Some rows in stop_times.txt leave the timepoint column blank. That column says whether a time is a real checkpoint or an estimate. Blank leaves apps guessing, and they may show your estimates as promises.
Estimated effort: Usually one export setting.
