Service mode Bus + Trolleybus
First scorecard for this agency
Catalogued in Pomorskie, Poland.
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 v1.2, validator 8.0.1.
Measured 3 of 4 score categories from the agency's own feed.
How we measured this
Confidence in this measurement: medium.
- Realtime quality was not measured this run. It does not count against the grade.
- The feed was downloaded from the agency's own URL.
Confidence describes how much the pipeline could measure this run, not the feed itself. It never changes the grade.
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
1153 of 1153 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.
⏱ A column in stops.txt; your scheduling software likely has it.worth about +25 points in its category
Add feed_info.txt with feed_start_date and feed_end_date to your export.Likely your export tool
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.
⏱ Two fields, set once in export settings.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.
⏱ A small file for most flat-fare systems.worth about +15 points in its category
How to make and check these changes

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 67 days.
- Published accessibility data
- Accessibility information is stated for 0% of stops and 100% 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
- Realtime-feed availability and live-arrival coverage are not known from this scorecard.
Important: This does not rate service reliability. Riders should confirm current service alerts, fares, and accessibility accommodations with the transit operator before traveling.

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
9 findings, ordered by severity.
Show every finding
- Warning2542 instances
The feed contains route shapes no trip uses.
Harmless to riders, but it bloats the feed and suggests stale export data.
Fix: Turn on 'remove unused shapes' (or the like) in your export tool. (One setting.)
Validator rule: unused_shape · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1153 instances
1153 of 1153 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.)
Validator rule: scorecard_wheelchair_boarding_unknown · Read the fix guide · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)
- Warning99 instances
Unexpected enum value (flagged by the MobilityData validator).
See the linked rule for what this affects.
Fix: Review the rule documentation for 'unexpected_enum_value' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

These IDs are valid UTF-8 data. This warning is only about support in older apps. It does not mean that names in other languages are wrong.
Fix: Only change the flagged IDs if an app needs basic ASCII values. Update each place that uses the ID. Keep all names and headsigns in their original language. (A planned ID change, not a quick text cleanup.)

A file GTFS asks for (usually feed_info.txt) is missing.
feed_info.txt tells apps who publishes the feed and when it expires; without it nobody is warned before data goes stale.
Fix: Add feed_info.txt with publisher name, URL, language, and feed_start_date/feed_end_date. (One small file, set once in export settings.)

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.
Fix: Add feed_info.txt with feed_start_date and feed_end_date to your export. (Two fields, set once in export settings.)

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.)

Unsorted stop times (flagged by the MobilityData validator).
See the linked rule for what this affects.
Fix: Review the rule documentation for 'unsorted_stop_times' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

- Info1 instance
feed_info.txt has no technical contact (feed_contact_email or feed_contact_url).
Trip-planning apps and regional data coordinators have nobody to email when they spot a problem with your feed, so problems linger.
Fix: Add feed_contact_email to feed_info.txt. (One field.)

Conformance mark Not yet
This feed is close to the conformance mark. States wheelchair access on 0% of stops and 100% of trips; the mark needs 90% of each.
- Valid Met
- Passes validation with no errors.
- Current Met
- Service data covers the next 67 days.
- Accessible Not yet
- States wheelchair access on 0% of stops and 100% 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.
Clears the Google and Apple Maps four-week coverage bar. This feed has 67 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 71 / 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 85 / 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 52 / 100
- GTFS Best Practices for rider-facing fields. MobilityData grading covers stop names and headsigns.
- Realtime quality Not yet published
- GTFS-Realtime best practices: a stable URL, high uptime, and frequent updates.

This page updates on every check. The record below does not: it is the dated file this grade came from, published at https://gtfsscorecard.org/data/artifacts/zkm-gdynia/2026-07-18.json and never overwritten, pinning the grade, category scores, rubric version, validator version, reader archive profile, and the scored feed's sha256 as they stood on 2026-07-18. Use it in a board packet, a regulatory filing, or a research citation instead of linking the live page, whose content will differ on your next visit.
