Source feed: https://bus-vision.jp/gtfs_v2/ikasabus/gtfsFeed

Ikasa Bus Company is based in Kasaoka, Okayama, and most of its 680 stops sit in the Kasaoka and Ibara area, so the record is filed under Okayama. Some routes cross into Fukuyama in Hiroshima, which is why the feed is published on the Hiroshima Bus Association site.

Heads-up: Days until the service window ends dropped by 22 between 2026-10-19 and 2026-10-20, but only 1 day(s) passed. The feed's calendar appears to have moved backward, which can happen when an older export is republished. Worth confirming the latest export is the one being served. (checked 2026-10-20). This can be a brief vendor export glitch; watch the next update before acting.

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

Ikasa Bus Company (井笠バスカンパニー)’s published feed lists 22 bus routes, 380 scheduled trips and 699 stops. Its service dates run from 2026-10-01 through 2026-12-31. It publishes realtime trip updates, vehicle positions and service alerts; when we checked, all of them answered. The published file last changed on 2026-10-20.

Top things to fix

Fix 01

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

699 of 699 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 699 stops in the feed.

⏱ A column in stops.txt; your scheduling software likely has it.worth about +25 points in its category

Fix 02

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

380 of 380 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 380 trips in the feed.

⏱ A default or per-trip field in your export.worth about +15 points in its category

Fix 03

Ask your AVL vendor to check that every vehicle assignment reaches TripUpdates. School-day and tripper runs are the ones most often left out.

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.

This was measured over a realtime sampling window, so it has no feed-wide share.

⏱ A vendor data-mapping question.worth about +10 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.

How to make and check these changes

Check the result on the published feed. Read the guide, make the change in your tool, and use the next comparable run to see whether the finding is still reported. Only an action or ticket record can attribute who made the change.

  1. Fix 01 · Read the fix guide for scorecard_wheelchair_boarding_unknown

    Make the change. Make this change in whatever tool produces your feed, then re-export.

    Check the result. The next scorecard run checks this finding again. If a comparable check no longer reports it, the feed's clearance log records that result. This confirms feed state, not who made the change. See this feed's finding-clearance log.

  2. Fix 02 · Read the fix guide for scorecard_wheelchair_accessible_unknown

    Make the change. Make this change in whatever tool produces your feed, then re-export.

    Check the result. The next scorecard run checks this finding again. If a comparable check no longer reports it, the feed's clearance log records that result. This confirms feed state, not who made the change. See this feed's finding-clearance log.

  3. Fix 03 · Read the fix guide for scorecard_rt_trip_coverage

    Make the change. Make this change in whatever tool produces your feed, then re-export.

    Check the result. The next scorecard run checks this finding again. If a comparable check no longer reports it, the feed's clearance log records that result. This confirms feed state, not who made the change. See this feed's finding-clearance log.

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 72 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 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.

Show every finding
  • Warning699 instances

    699 of 699 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)

  • Warning547 instances

    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.)

    Finding code: missing_recommended_field · Read the fix guide for missing_recommended_field · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning380 instances

    380 of 380 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.)

  • Warning53 instances

    Same name and description for stop (flagged by the MobilityData validator).

    See the linked rule for what this affects.

    Fix: Review the rule documentation for 'same_name_and_description_for_stop' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

    Finding code: same_name_and_description_for_stop · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning32 instances

    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.)

    Finding code: stop_without_stop_time · Read the fix guide for stop_without_stop_time · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning26 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)

  • Warning1 instance

    Two or more routes share the same name.

    Riders can't tell the routes apart in apps.

    Fix: Give each route a distinct short or long name. (One field per route.)

    Finding code: duplicate_route_name · 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)

  • Warning1 instance

    Many of the feed's trips don't run at all in the next 7 days.

    It usually means old service periods are still in the export, making the feed bigger and harder to check.

    Fix: Trim past service periods the next time you export. (One setting in most export tools.)

    Finding code: trip_coverage_not_active_for_next7_days · Read the fix guide for trip_coverage_not_active_for_next7_days · See MobilityData GTFS Validator rules (opens the validator rules 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 for scorecard_rt_trip_coverage · See GTFS-Realtime reference (opens the GTFS-Realtime reference on an external site)

  • Info4 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)

  • Info3 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

    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.)

    Finding code: big_gap_in_service · Read the fix guide for big_gap_in_service · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Info1 instance

    Feed valid beyond total service window (flagged by the MobilityData validator).

    See the linked rule for what this affects.

    Fix: Review the rule documentation for 'feed_valid_beyond_total_service_window' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

    Finding code: feed_valid_beyond_total_service_window · 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

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 72 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.

  • 32 of 699 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 200 checks in the 25 days to 2026-10-20, with 48s 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 84s late versus the schedule, and stayed within 89s nine times in ten. They were on time (about a minute early to five late) 100.0% 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 71 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 58 / 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 90 / 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/ikasa-bus/2026-10-20.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 2026-10-20. 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.
