How we measured this
Confidence in this measurement: high.
- All four score categories were measured this run.
- Realtime was sampled in one bounded window of 6 snapshots.
- The feed was downloaded from the official feed URL on file.
Confidence describes how much the pipeline could measure this run, not the feed itself. It never changes the grade.
About this feed
Réseau urbain et scolaire Guingamp-Paimpol Mobilité’s published feed lists 6 bus routes, 285 scheduled trips and 118 stops. Its service dates run from 2026-08-28 through 2028-07-03. It publishes realtime trip updates and vehicle positions; when we checked, all of them answered. The published file has not changed since our first check on 2026-09-01.
Top things to fix
Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.Likely your team
118 of 118 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.
Fixing this covers all 118 stops in the feed.
⏱ A column in stops.txt; your scheduling software likely has it.worth about +25 points in its category
Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip.Likely your export tool
285 of 285 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.
Fixing this covers all 285 trips in the feed.
⏱ A default or per-trip field in your export.worth about +15 points in its category
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.

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.

Rider view: what this feed publishes
A quick read of rider-facing information in this feed.
- Schedule visibility
- The feed's last published service date is in 626 days.
- Published accessibility data
- Accessibility information is stated for 0% of stops and 0% of trips. This measures published data, not whether stops or vehicles are physically usable.
- Fare information
- No fare information is published in the feed.
- Realtime information
- Live-arrival data covered 100% of scheduled trips in the sampled window.
Important: This does not rate service reliability. Riders should confirm current service alerts, fares, and accessibility accommodations with the transit operator before traveling.

285 of 285 trips don't say whether the vehicle is wheelchair accessible.
Even with accessible stops, riders need to know the bus itself can take them.
Fix: Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip. (A default or per-trip field in your export.)

Some service calendars in the feed have already ended.
Expired calendars are dead weight and can hide real schedule problems from your staff and vendors.
Fix: Remove past service periods the next time you export the feed. (One setting in most export tools.)

Some stops exist in the feed but no trip ever stops at them.
Riders may walk to a stop where no bus is scheduled to arrive.
Fix: Remove retired stops from the export, or add them back to the trips that should serve them. (A review pass in your scheduling software.)

feed_info.txt lists no contact email and no contact URL.
Without a contact, apps like Google Maps can't reach you when they find a problem in the feed.

Some files leave out fields that GTFS asks for but does not require.
Recommended fields like agency_phone or stop descriptions make the feed more useful to riders and trip planners.
Fix: Review the flagged fields and fill in the ones your riders would use. (A field at a time; not urgent.)

Trip with shape dist traveled but no shape distances (flagged by the MobilityData validator).
See the linked rule for what this affects.
Fix: Review the rule documentation for 'trip_with_shape_dist_traveled_but_no_shape_distances' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

The feed has a stretch of two weeks or more with no service running.
A long gap can mean dates were left out of the calendar. Apps then show no trips on those days.
Fix: Check whether the gap is real, like a seasonal break; if not, add the missing dates to the calendar. (A review of your calendar dates.)

feed_info.txt has no technical contact (feed_contact_email or feed_contact_url).
App makers and state data programs have nobody to email when they spot a problem. Small errors then sit in the feed for months.

Conformance mark Not yet
One requirement remains for this feed to earn the conformance mark. States wheelchair access on 0% of stops and 0% of trips; the mark needs 90% of each.
- Valid Met
- Passes validation with no errors.
- Current Met
- Service data covers the next 626 days.
- Accessible Not yet
- States wheelchair access on 0% of stops and 0% of trips; the mark needs 90% of each.
In plain words: earn this mark when your feed passes validation, has not expired, and says whether nearly every stop and trip is wheelchair accessible.
A pass credential for a feed that is valid, current, and states wheelchair access on nearly every stop and trip. Accessibility here measures what the feed publishes, not whether a stop is physically usable. How the conformance mark works.
Can riders use it?
Checks beyond structural validation: places where the feed is valid but a rider still could not travel.
- 2 of 118 boardable stops are never served by any trip. Riders see these stops in apps and on the map but can never catch anything there, which erodes trust in the data. Remove stops no route serves, or add the trips that should call at them.
These do not change the grade. They catch trips with no rideable leg and stops no trip serves, the kind of gap a trip planner trips over.
Realtime reliability
The realtime feed responded on 99.5% of 200 checks in the 25 days to 2026-10-16, with 22s median lag.
Sampled on a schedule between full scores, so this tracks uptime and freshness over time rather than at a single moment. The window ends at the newest observation, which is not always today: if the monitor stops, this window stops with it.
Live predictions vs schedule
Arrival predictions ran a median 70s late versus the schedule, and stayed within 285s nine times in ten. They were on time (about a minute early to five late) 87.0% of the time. 100.0% of reported vehicle positions sat on or near the published route shape.
From the last full realtime sample: how far live arrival predictions sat from the schedule, and whether vehicle positions fell on the route. These feed the realtime score; they change no other category.
Clears the Google and Apple Maps four-week coverage bar. This feed has 626 days of service ahead, clearing the four-week (28-day) window Maps asks for. No validator errors either, so riders keep seeing this agency in their trip planners; warnings lower the grade here but do not remove a feed from Maps.
How this agency maps to the standards
The scorecard is a data-quality lens, not a compliance determination. Its universal references describe good GTFS and useful rider information. Useful references here are GTFS Schedule Best Practices, GTFS-Realtime Best Practices, MobilityData grading scheme, Google Transit publication guidance. Read the full standards crosswalk.
- Correctness 82 / 100
- GTFS Schedule best practices, checked by the MobilityData validator. MobilityData grading covers stop locations, route names, and colors. Google Transit requires a feed to pass validation for publication.
- Freshness 100 / 100
- GTFS Schedule best practices call for a dataset that stays current. An expired calendar can remove service from Google Transit and other rider trip planners.
- Rider experience 38 / 100
- GTFS Best Practices for rider-facing fields. MobilityData grading covers stop names and headsigns.
- Realtime quality 100 / 100
