Get GTFS-Schedule validation report for feeds or datasets

Extract validation report summary from feed/dataset results. MobilityData runs all GTFS Schedule feeds through the canonical GTFS validator, and this function surfaces that validation data to help assess feed quality before downloading.

Note: This function does not support GBFS validation reports at this time as GBFS validation reports are located at a different endpoint and have a different validation criteria.

Usage

get_validation_report(data)

Arguments

data

A tibble from feeds(), mobdb_datasets(), or mobdb_search().

Value

A tibble with validation summary information:

• feed_id or dataset_id - Identifier

• provider - Provider name (if available)

• total_error - Number of validation errors

• total_warning - Number of validation warnings

• total_info - Number of informational notices

• html_report - URL to full HTML validation report

• json_report - URL to JSON validation report

Examples

if (FALSE) { # \dontrun{
# Get validation report for feeds from search
bart_feeds <- feeds(provider = "Bay Area Rapid Transit")
datasets <- mobdb_datasets(bart_feeds$id[1])
validation <- get_validation_report(datasets)
print(validation)

# Check TransLink Vancouver's validation (has known warnings)
# Per TransLink's GTFS page "We pass our data through Google's Transit Feed
# Validator at the error level, but the data may have warnings left unfixed
# in order to conform to TransLink's business rules, such as duplicate stops
# with no distance between them."
vancouver <- feeds(provider = "TransLink", country_code = "CA", data_type = "gtfs")
vancouver_datasets <- mobdb_datasets(vancouver$id[1])
validation <- get_validation_report(vancouver_datasets)
# Shows: 100,076 errors, 14,322,543 warnings
