Marin Transit

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

   Trip distance exceeds shape distance (flagged by the MobilityData validator). See the linked rule for what this affects.

   Estimated effort: Varies.

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

   Missing required column (flagged by the MobilityData validator). See the linked rule for what this affects.

   Estimated effort: Varies.

3. Set wheelchair_accessible on every trip (most small-agency fleets are 100% accessible, so this is often a single default).

   532 of 1612 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: Often one default setting in your export.

   Agencies here usually clear this within about 1 week (based on 5 observed fixes).
