gtfs-rt-parser

This script parses GTFS RT protobufs into newline-delimited JSON for querying via BigQuery external tables. This script aggregates data hourly, so we can fit within BigQuery external table file count limits.

Running automated tests

1. Install uv dependencies for airflow:

$ uv sync

2. Run gtfs-rt-parser tests:

GTFS-RT Validator JAR file

The gtfs-realtime-validator-lib-x.y.z-yyyymmdd.HHMMss-v.jar is an old snapshot of the GTFS Realtime validator that now lives under MobilityData. We've vendored an old version to help make our builds less dependent on external services. We should begin using the officially-published packages at some point in the future.
