BWI Thurgood Marshall Airport (BWI) Shuttle

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.

What needs attention next

Three improvements, in priority order, each sized so the board can see what it is approving:

1. Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change.

   Service data ended 1309 day(s) ago. When the calendar runs out, trip planners stop showing this agency even though the buses are still running. Riders are told the service does not exist.

   Estimated effort: Usually one export setting; export on a schedule so it never lapses again.

2. Review the rule documentation for 'stop_time_timepoint_without_times' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

   Stop time timepoint without times (flagged by the MobilityData validator). See the linked rule for what this affects.

   Estimated effort: Varies.

3. Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip.

   10 of 10 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.

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.
