Metropolitan Atlanta Rapid Transit Authority (MARTA)

What changed since the last check

• Correctness no change
• Freshness down 1.7
• Rider experience no change
• Realtime quality no change

Top three things to fix

1. Check the service alerts endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request.

   The service alerts realtime feed failed during sampling. When this feed is down, riders see scheduled times presented as if they were live.

   Effort: Usually a vendor support ticket.

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.

   Effort: A small file for most flat-fare systems.

3. 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.

   Effort: Two fields, set once in export settings.

NTD GTFS readiness: Ready

This feed looks ready for your NTD certification: published at a public URL, valid, and current. The official check is still your D-10 certification.

Published Ready

Published at a public URL.

Valid Ready

Passes validation with no errors.

Current Ready

Service data covers the next 52 days.

agency_id and NTD ID: Not checked yet. Setting your GTFS agency_id to your five-digit NTD ID is an optional way to line a feed up with its National Transit Database record. FTA links the two on your P-50 form, so it is not a required feed change. We don't have your NTD ID on file, so this is not checked yet.
