Philly PHLASH
Grade A · 90.6 / 100
Unchanged since 2026-08-01.
What this grade measures
The quality of the schedule data this agency publishes 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:
Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip.
645 of 661 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.
Estimated effort: A default or per-trip field in your export.
Remove past service periods the next time you export the feed.
Some service calendars in the feed have already ended. Expired calendars are dead weight and can hide real schedule problems from your staff and vendors.
Estimated effort: One setting in most export tools.
Trim past service periods the next time you export.
Many of the feed's trips don't run at all in the next 7 days. It usually means old service periods are still in the export, making the feed bigger and harder to check.
Estimated effort: One setting in most export tools.
This feed is published from a code repository, so whoever maintains that repository regenerates the zip — often planning staff or a consultant. The fix happens in the source data, then a fresh export is committed.
