First scorecard for this agency
Catalogued in Auvergne-Rhône-Alpes, France.
A data-quality and completeness lens to help an agency improve its GTFS feed. Not an official compliance determination from any transit program. New to this? How to read your scorecard. Interactive view of this scorecard. Rubric v1.3, validator 8.0.1.
Checked for changes 1 hours ago; last changed 1 hours ago.
Measured 4 of 4 score categories from the official feed URL on file.
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 3 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.
Top things to fix

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 304 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 75% 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.

You may not control the GTFS export yourself. Copy this and send it to whoever runs your scheduling software export. It names each fix with the validator notice and a guide link.
Score by category
The MobilityData validator flagged 4 kinds of issue across 104 instances (41 error, 63 warning, 0 informational).
Service data covers the next 304 days.
0% of stops state wheelchair accessibility (0% marked accessible, 0% marked not accessible). This measures what the feed publishes, not whether a stop is physically usable. Fare data is not published.
0% of stops state accessibility (0% marked accessible). Reflects what the feed states, not verified physical usability.
2 accessibility depth signals
1 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (LC).
Consider: Adjust route_color or route_text_color so each pair clears 4.5:1. Often switching the text between black and white is enough.
4 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("GARE DE ST MAURICE DE BEYNOST", "ST MAURICE DE BEYNOST MAIRIE", "GARE DE ST MAURICE DE BEYNOST", and more).
Consider: Add tts_stop_name with the spoken form, e.g. 'Main Street and Second Avenue', for the affected stops.
Opportunities to strengthen the data, not deductions from the sub-score above. States what the second accessibility lens can check from the feed, not verified physical usability.
Sampled 3 times: 1 of 1 configured feed healthy; 75.0% of scheduled trips had live predictions; predictions ran a median of 460s behind schedule.
Routes and stops
Each route is drawn once, using the longest shape its trips follow; stops are the dots.
This feed has 67 stops.

Over time
This is the first scorecard for this agency. A trend and a "what changed" summary appear here once it has been checked more than once.
Everything we checked
11 findings, ordered by severity.
Show every finding
- Error41 instances
Some trips have stop times whose distances along the route go backwards.
Apps can show buses jumping backwards or mis-order stops.
Fix: Re-generate shape distances in your export; flag to your vendor if it persists. (Usually an export-tool fix, not hand editing.)
Finding code: decreasing_or_equal_stop_time_distance · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning120 instances
Some live predictions are more than 30 minutes away from the schedule.
Differences that large usually mean predictions are keyed to the wrong trips, not that buses are that late.
Fix: Spot-check the flagged predictions against what buses actually did; raise trip-matching with your AVL vendor. (A vendor data-mapping question.)
Finding code: scorecard_rt_predictions_implausible
- Warning67 instances
67 of 67 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.
Fix: Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops. (A column in stops.txt; your scheduling software likely has it.)
Finding code: scorecard_wheelchair_boarding_unknown · Read the fix guide · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)
- Warning64 instances
64 of 64 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.)
Finding code: scorecard_wheelchair_accessible_unknown · Read the fix guide · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)
- Warning51 instances
Some rider-facing names are in ALL CAPS or all lowercase.
ALL-CAPS stop and headsign names are harder to read in apps and are read awkwardly by screen readers.
Fix: Use mixed case for stop names and headsigns (e.g. 'Main St & 2nd Ave', not 'MAIN ST & 2ND AVE'). (Often a bulk fix in your scheduling software.)
Finding code: mixed_case_recommended_field · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning11 instances
On some trips the stop distances run a little past the end of the route line.
The stop and shape distance values don't quite line up, so any math that uses them can drift.
Fix: Re-generate shape_dist_traveled on export so stop and shape distances use the same units. (Usually an export-tool fix, not hand editing.)
Finding code: trip_distance_exceeds_shape_distance_below_threshold · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
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.
Fix: Add feed_contact_email or feed_contact_url to feed_info.txt. (One field, set once in export settings.)
Finding code: missing_feed_contact_email_and_url · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
The feed contains no fare information.
Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.
Fix: 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. (A small file for most flat-fare systems.)
Finding code: scorecard_no_fare_data · Read the fix guide · See GTFS Best Practices (opens GTFS Best Practices on an external site)
- Warning1 instance
1 of 4 trips scheduled during the sampling window had no live predictions.
Riders on those trips get schedule times labeled as live. Caltrans asks that every trip you run shows up in TripUpdates.
Fix: Ask your AVL vendor to check that every vehicle assignment reaches TripUpdates. School-day and tripper runs are the ones most often left out. (A vendor data-mapping question.)
Finding code: scorecard_rt_trip_coverage · Read the fix guide · See GTFS-Realtime reference (opens the GTFS-Realtime reference on an external site)
- Info67 instances
About 67 stop names are written in ALL CAPS.
Mixed-case names are easier to read in apps and are read more naturally by screen readers.
Fix: Rename stops to mixed case where the language has letter case (for example, 'Central Station'). (Often a bulk fix in your scheduling software.)
Finding code: scorecard_stop_names_all_caps · Read the fix guide · See GTFS Best Practices (opens GTFS Best Practices on an external site)
- Info1 instance
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.
Fix: Add feed_contact_email to feed_info.txt. (One field.)
Finding code: scorecard_no_feed_contact · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
Conformance mark Not yet
Two requirements remain for this feed to earn the conformance mark. 1 validator error to resolve. States wheelchair access on 0% of stops and 0% of trips; the mark needs 90% of each.
- Valid Not yet
- 1 validator error to resolve.
- Current Met
- Service data covers the next 304 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.
Realtime reliability
The realtime feed responded on 100.0% of 5 checks over the last 1 day, with 0s median lag.
Sampled on a schedule between full scores, so this tracks uptime and freshness over time rather than at a single moment.
Live predictions vs schedule
Arrival predictions ran a median 460s late versus the schedule, and stayed within 7270s nine times in ten. They were on time (about a minute early to five late) 24.2% of the time.
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 304 days of service ahead, clearing the four-week (28-day) window Maps asks for. The feed also carries 41 validator errors, the other thing Maps checks at onboarding; the findings below name each fix.
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 64 / 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 22 / 100
- GTFS Best Practices for rider-facing fields. MobilityData grading covers stop names and headsigns.
- Realtime quality 90 / 100
- GTFS-Realtime best practices: a stable URL, high uptime, and frequent updates.
