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 v1.1, validator 8.0.1.
Checked for changes 18 minutes ago; last changed 3 hours ago.
Measured 4 of 4 score categories from the agency's own feed.
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 9 snapshots.
- 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
Check the trip updates endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request.
The trip updates realtime feed failed during sampling. When this feed is down, riders see scheduled times presented as if they were live.
⏱ Usually a vendor support ticket.worth about +8 points
Agencies here usually clear this within about 1 week (based on 11 observed fixes).
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
1314 of 1314 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
Set wheelchair_accessible on every trip (most small-agency fleets are 100% accessible, so this is often a single default).Likely your export tool
1345 of 1345 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.
⏱ Often one default setting in your export.worth about +15 points
Agencies here usually clear this within about 1 week (based on 5 observed fixes).

Score by category
The MobilityData validator flagged 5 kinds of issue across 2544 instances (0 error, 2543 warning, 1 informational).
Service data covers the next 30 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.
3 accessibility depth signals
2 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (5, 7).
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.
1224 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("WESTBROOK ST + UPPER COACH RD", "WESTBROOK ST + LOWER COACH RD", "COTTAGE RD + SOULE ST", and more).
Consider: Add tts_stop_name with the spoken form, e.g. 'Main Street and Second Avenue', for the affected stops.
This feed models stations or entrances but has no pathways.txt and levels.txt.
Consider: Add pathways.txt connecting entrances, platforms, and elevators, and levels.txt for each floor, so the step-free route is described.
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 9 times outside service hours: 2 of 3 feeds healthy; 0.0% of vehicles on their route.

Everything we checked
- Error1 instance
The trip updates realtime feed failed during sampling.
When this feed is down, riders see scheduled times presented as if they were live.
Fix: Check the trip updates endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request. (Usually a vendor support ticket.)
Agencies here usually clear this within about 1 week (based on 11 observed fixes).
Validator rule: scorecard_rt_trip_updates_unreachable · Read the fix guide · See GTFS-Realtime reference (opens the GTFS-Realtime reference on an external site)
- Warning2356 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.)
Validator rule: mixed_case_recommended_field · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1345 instances
1345 of 1345 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 (most small-agency fleets are 100% accessible, so this is often a single default). (Often one default setting in your export.)
Agencies here usually clear this within about 1 week (based on 5 observed fixes).
Validator rule: scorecard_wheelchair_accessible_unknown · Read the fix guide · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)
- Warning1314 instances
1314 of 1314 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)
- Warning196 instances
196 of 1345 trips have no headsign.
Riders at the stop can't tell which direction a bus is going.
Fix: Populate trip_headsign to match what the bus displays. (Usually a bulk edit in your scheduling software.)
Validator rule: scorecard_missing_headsigns · Read the fix guide · See GTFS Best Practices (opens GTFS Best Practices on an external site)
- Warning185 instances
Equal shape distance diff coordinates distance below threshold (flagged by the MobilityData validator).
See the linked rule for what this affects.
Fix: Review the rule documentation for 'equal_shape_distance_diff_coordinates_distance_below_threshold' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)
Validator rule: equal_shape_distance_diff_coordinates_distance_below_threshold · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning2 instances
2 of 2 sampled vehicle positions were far from their assigned route (worst: 1951 m).
A bus shown off its route usually means a wrong trip assignment; riders watch their bus drive the wrong streets.
Fix: Ask your AVL vendor to check vehicle-to-trip assignments for the flagged trips. (A vendor support ticket with the trip ids attached.)
Agencies here usually clear this within about 1 week (based on 31 observed fixes).
Validator rule: scorecard_rt_vehicles_off_route
- Warning1 instance
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.)
Agencies here usually clear this within about 1 week (based on 13 observed fixes).
Validator rule: missing_recommended_file · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
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.)
Agencies here usually clear this within about 1 week (based on 11 observed fixes).
Validator rule: stop_without_stop_time · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
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.)
Agencies here usually clear this within about 1 week (based on 16 observed fixes).
Validator rule: scorecard_missing_feed_info_dates · 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.)
Validator rule: scorecard_no_fare_data · Read the fix guide · See GTFS Best Practices (opens GTFS Best Practices on an external site)
- Warning1 instance
This feed models stations or entrances but has no pathways.txt.
Trip planners can't guide riders through the station, and there is no step-free route information for wheelchair users.
Fix: Add pathways.txt connecting entrances, platforms, and any elevators, with a level for each. (Worth it for multi-level or large stations; flat stops don't need it.)
Validator rule: scorecard_station_no_pathways · Read the fix guide · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)
- Info1280 instances
About 1280 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 (e.g. 'Main St & 2nd Ave'). (Often a bulk fix in your scheduling software.)
Validator rule: scorecard_stop_names_all_caps · Read the fix guide · See GTFS Best Practices (opens GTFS Best Practices on an external site)
- Info1 instance
Some files contain columns that are not part of the GTFS spec.
Harmless to riders, but apps ignore these columns and they can hide typos in real column names.
Fix: Check the flagged column names for misspellings of standard GTFS fields; remove them if they are vendor extras. (A quick look at the flagged files.)
Validator rule: unknown_column · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules 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 with your feed, so problems linger.
Fix: Add feed_contact_email to feed_info.txt. (One field.)
Agencies here usually clear this within about 1 week (based on 10 observed fixes).

NTD certification readiness Needs attention
This feed is close to NTD-ready. Service data runs out in 30 days; renew before you certify.
- Published Ready
- Published at a public URL.
- Valid Ready
- Passes validation with no errors.
- Current Needs attention
- Service data runs out in 30 days; renew before you certify.
- agency_id matches your 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.
- shapes.txt covers your trips Ready
- All 1345 trips have a shape in shapes.txt.
In plain words: if you report to the federal transit database, you have to publish a working, up-to-date feed and confirm it once a year. This box is a heads-up on whether yours looks ready; it is not the official sign-off.
A readiness signal mapping this feed to the FTA National Transit Database GTFS requirement (Report Year 2023 onward: a public, valid, current feed, certified annually on the D-10). Aligning agency_id with your NTD ID lets the feed line up with your NTD record; the July 2025 final rule links the two on the P-50 form rather than requiring that feed change, and requires shapes.txt in the published GTFS: Full Reporters from Report Year 2025, and Reduced, Rural, and Tribal Reporters from Report Year 2026. Not an official determination; your certification is the official check.
Conformance mark Not yet
This feed is close to the conformance mark. Service data runs out in 30 days; renew to qualify. 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 Not yet
- Service data runs out in 30 days; renew to qualify.
- 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.
- 1 of 657 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 100.0% of 106 checks over the last 16 days, with 3s median lag.
Sampled on a schedule between full scores, so this tracks uptime and freshness over time rather than at a single moment.
Prediction accuracy
0.0% 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 30 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
A data-quality lens, not a compliance determination. Each category shows this feed's score and the standards it relates to: the FTA National Transit Database GTFS requirement, the MobilityData grading scheme, and the Google Transit gate. Read the full standards crosswalk.
- Correctness 76 / 100
- GTFS Schedule best practices, checked by the MobilityData validator. MobilityData grading: stop locations, route names and colors. Google Transit: a feed must pass validation to stay in Maps.
- Freshness 35 / 100
- The FTA National Transit Database expectation of a valid, current feed. Google Transit: an expired calendar drops the agency from Maps.
- Rider experience 21 / 100
- GTFS Best Practices for rider-facing fields. MobilityData grading: stop names and headsigns.
- Realtime quality 64 / 100
- GTFS-Realtime best practices: a stable URL, high uptime, and frequent updates.
Cite this record
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/greater-portland-metro-bus-2642/2026-07-09.json and never overwritten, pinning the grade, category scores, rubric version, validator version, and the scored feed's sha256 as they stood on 2026-07-09. Use it in a board packet, an NTD narrative, or a research citation instead of linking the live page, whose content will differ on your next visit.
