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 v1.4, validator 8.0.1.
Checked for changes 4 hours ago; last changed 12 days 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 9 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
Hiroshima Bus (広島バス)’s published feed lists 29 bus routes, 3,427 scheduled trips and 635 stops. Its service dates run from 2026-10-09 through 2027-04-09. It publishes realtime trip updates, vehicle positions and service alerts; when we checked, all of them answered. The published file last changed on 2026-10-08.
Top things to fix
Add the required column named in the finding to the flagged file.Likely your export tool
A file is missing a column that GTFS requires. Apps may reject the whole file, so riders could lose the affected routes or stops.
This is a validator notice, and the validator decides what each instance covers, so no share of the network can be read from it here.
⏱ Often an export setting; ask your vendor if it recurs.worth about +12 points in its category
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
635 of 635 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 635 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
3427 of 3427 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 3,427 trips in the feed.
⏱ A default or per-trip field in your export.worth about +15 points in its category
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 171 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
- Fare information is published using GTFS Fares v1.
- 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.

Score by category
The MobilityData validator flagged 9 kinds of issue across 87684 instances (3 error, 87586 warning, 95 informational).
Service data covers the next 171 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 published.
0% of stops state accessibility (0% marked accessible). Reflects what the feed states, not verified physical usability.
Fares are applied to trips.
Sampled 9 times: 3 of 3 configured feeds healthy; 100.0% of scheduled trips had live predictions; 100.0% of vehicles on their route; predictions ran a median of 0s behind schedule.

Everything we checked
13 findings, ordered by severity.
Show every finding
- Error3 instances
A file is missing a column that GTFS requires.
Apps may reject the whole file, so riders could lose the affected routes or stops.
Fix: Add the required column named in the finding to the flagged file. (Often an export setting; ask your vendor if it recurs.)
Finding code: missing_required_column · Read the fix guide for missing_required_column · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning83941 instances
Some rows in stop_times.txt leave the timepoint column blank.
That column says whether a time is a real checkpoint or an estimate. Blank leaves apps guessing, and they may show your estimates as promises.
Fix: Set timepoint=1 on stops that are real time checks and 0 on the rest. If every published time is a scheduled one, mark them all 1. (Usually one export setting.)
Finding code: missing_timepoint_value · Read the fix guide for missing_timepoint_value · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning3472 instances
Some internal IDs use characters outside the basic text set.
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.)
Finding code: non_ascii_or_non_printable_char · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning3427 instances
3427 of 3427 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 for scorecard_wheelchair_accessible_unknown · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)
- Warning635 instances
635 of 635 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 for scorecard_wheelchair_boarding_unknown · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)
- Warning155 instances
155 of 3427 trips have no headsign, the text that tells riders where the bus is going. A trip counts when it has trip_headsign or a stop_headsign at every stop.
When a route has multiple directions or patterns, the route name alone may not tell riders which service is coming.
Fix: Add the destination, direction, or 'via' label riders actually see to trip_headsign. Do not copy the route name. If the label changes during the trip, use stop_headsign. (Usually one value per route pattern in your scheduling source.)
Finding code: scorecard_missing_headsigns · Read the fix guide for scorecard_missing_headsigns · See GTFS Best Practices (opens GTFS Best Practices on an external site)
- Warning140 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 for mixed_case_recommended_field · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning32 instances
Some stops sit far from the route line they belong to.
Trip planners may draw the bus route through the wrong streets or point riders to the wrong corner.
Fix: Check the flagged stops' coordinates and the route shape in your scheduling software; re-snap whichever is misplaced. (A few minutes per flagged stop.)
Finding code: stop_too_far_from_shape · Read the fix guide for stop_too_far_from_shape · 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 for missing_feed_contact_email_and_url · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Info82 instances
Platform without parent station (flagged by the MobilityData validator).
See the linked rule for what this affects.
Fix: Review the rule documentation for 'platform_without_parent_station' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)
Finding code: platform_without_parent_station · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Info11 instances
The feed includes a file that is not part of the GTFS spec.
Apps ignore files they don't know, and a stray file can hide a misspelled standard file name.
Fix: Check the flagged file name for a typo of a standard GTFS file. Remove it if it is a vendor extra. (A quick look at the flagged file.)
Finding code: unknown_file · Read the fix guide for unknown_file · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Info2 instances
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.)
Finding code: unknown_column · Read the fix guide for unknown_column · 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. Small errors then sit in the feed for months.
Fix: Add feed_contact_email to feed_info.txt. (One field.)

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 171 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 200 checks in the 25 days to 2026-10-20, with 21s 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 right on the schedule, and stayed within 0s nine times in ten. They were on time (about a minute early to five late) 96.2% 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 170 days of service ahead, clearing the four-week (28-day) window Maps asks for. The feed also carries 3 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 52 / 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 52 / 100
- GTFS Best Practices for rider-facing fields. MobilityData grading covers stop names and headsigns.
- Realtime quality 100 / 100
- GTFS-Realtime best practices: a stable URL, high uptime, and frequent updates.
