McGill's Buses

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:

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

   Duplicate key (flagged by the MobilityData validator). See the linked rule for what this affects.

   Estimated effort: Varies.

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

   Block trips with overlapping stop times (flagged by the MobilityData validator). See the linked rule for what this affects.

   Estimated effort: Varies.

3. Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.

   2518 of 2518 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.
