Trinity Metro

5820 of 5820 trips don't say whether the vehicle is wheelchair accessible.

Even with accessible stops, riders need to know the transit vehicle 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.)

1611 of 1611 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.)

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.)

Some scheduled trips move faster between stops than a transit vehicle can.

Usually a typo'd stop time; riders get arrival times no transit vehicle can meet.

Fix: Check the flagged stop times for transposed minutes. (A few minutes per flagged trip.)

Some route long names repeat the route's short name inside them.

Apps show both names together, so riders see the number twice, like '5 5 Downtown'.

Fix: Drop the short name from route_long_name and keep the long name descriptive, like 'Downtown via 5th Ave'. (One field per flagged route.)

Some route colors don't contrast with their text color.

Route badges get hard to read, most of all for riders with low vision.

Fix: Pick a darker/lighter route_text_color for the flagged routes. (One field per route.)

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.)

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.)

Some stops sit far from the route line, going by the feed's own distance values.

Trip planners may draw the route down the wrong path or point riders to the wrong boarding location.

Fix: Check the flagged stops' shape_dist_traveled against the route shape, and re-generate it on export if they disagree. (Usually an export-tool fix, not hand editing.)

On some trips the stops fall along the route line in a different order than the schedule lists.

Trip planners can draw the transit vehicle doubling back or skipping ahead, which confuses riders reading the map.

Fix: Check the stop order and the shape direction in your scheduling software; the shape is often drawn backwards. (A few minutes per flagged trip.)

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.)

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.)

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.)
