Grade C · 77.4 / 100

What this grade measures

The quality of the schedule data in the feed scored here 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 the destination, direction, or 'via' label riders actually see to trip_headsign. Do not copy the route name. If the label changes during the trip, use stop_headsign.

    1649 of 1649 trips have no headsign, the text that tells riders where the vessel is going. A trip counts when it has trip_headsign or a stop_headsign at every terminal. When a route has multiple directions or patterns, the route name alone may not tell riders which service is coming.

    Fixing this covers all 1,649 trips in the feed.

    Estimated effort: Usually one value per route pattern in your scheduling source.

  2. 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.

    This one is about the feed as a whole, so there is no share of it to count.

    Estimated effort: Two fields, set once in export settings.

  3. 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.

    This one is about the feed as a whole, so there is no share of it to count.

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

Riders and need behind these fixes

  • Rider-trip figures come from the United States National Transit Database, which does not cover this feed's country.
  • The served-area need overlays cover the United States and Canada, so none of them applies to this feed.

These describe this feed only. They do not rank agencies, and they do not change the grade or the order of the fixes.
