Toronto Transit Commission (TTC)

Grade D · 63.0 / 100

First check for this agency, so there is no trend yet.

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. 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.

  2. Add fare_attributes.txt (or Fares v2 files) with your fare structure. If your service is fare-free, ask to have it marked fare-free instead.

    The feed contains no fare information. Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.

    Estimated effort: A small file for most flat-fare systems.

  3. Check the flagged stops' shape_dist_traveled against the route shape, and re-generate it on export if they disagree.

    Some stops sit far from the route line, going by the feed's own distance values. Trip planners may draw the route down the wrong path or point riders to the wrong boarding location.

    Estimated effort: Usually an export-tool fix, not hand editing.
