| # South Australia public transport |
|
|
| The Adelaide Metro General Transit Feed (buses, trains and trams in metropolitan Adelaide, plus the regional coach operators |
| the same feed carries, such as Stateliner) as GeoParquet, JSON and vector tiles, rebuilt weekly by |
| [milleleaf/sa-transit](https://github.com/milleleaf/sa-transit), with a snapshot of the GTFS-realtime feeds (vehicle |
| positions, trip updates and service alerts) every 15 minutes. Every table, row and field of the source is kept. |
|
|
| | File | Holds | |
| |---|---| |
| | `gtfs/<table>.parquet` | Every table of the feed (`agency`, `routes`, `trips`, `stop_times`, `stops`, `shapes`, `calendar`, `calendar_dates`, `transfers`, `booking_rules`, `feed_info`, and any table added later), every column as text, exactly as published | |
| | `release-notes.txt` | The feed's own release notes | |
| | `stops.parquet` | GeoParquet: every stop, every column, with a point geometry | |
| | `route-shapes.parquet` | GeoParquet: one row per route and shape a trip uses: every route column, `shape_id`, `trips`, `points`, `shape_dist_traveled`, and the shape as a line | |
| | `stops.json` | GeoJSON of every stop, every field | |
| | `routes.json` | Every route, every field, with its `shape_ids` and `trips` | |
| | `transit.pmtiles` | Vector tiles, layers `routes` and `stops`, zooms 4 to 14; every feature is in every zoom | |
| | `index.json` | Row counts, the tables, and the feed's `feed_info` (version and validity dates) | |
|
|
| ## Live feeds (bucket only) |
|
|
| On the [bucket](https://huggingface.co/buckets/milleleaf/sa-transit), refreshed every 15 minutes (GitHub may start a run |
| late or skip one, so the history has gaps). Three GTFS-realtime feeds, each as `<feed>`: |
|
|
| | `<feed>` | Feed | Daily Parquet: one row per | |
| |---|---|---| |
| | `vehicles` | vehicle positions | vehicle per snapshot (GeoParquet, a point per vehicle) | |
| | `trip_updates` | trip updates (predicted arrivals and departures) | trip per snapshot; `stop_time_updates` counts its stop predictions, which are in `entity` | |
| | `alerts` | service alerts (disruptions, stop changes) | alert per snapshot | |
|
|
| | File | Holds | |
| |---|---| |
| | `live/<feed>.json` | The latest feed decoded to JSON, every field, including the feed's own vehicle extension (`air_conditioned`, `wheelchair_accessible` as `tfnsw_vehicle_descriptor` on every vehicle descriptor) | |
| | `live/<feed>.pb` | The same feed as received (protobuf) | |
| | `live/<feed>-YYYY-MM-DD.parquet` | Every entity in every snapshot of that UTC day, with the main fields as columns and `entity`, the full entity as JSON | |
|
|
| `snapshot` is the feed's own header timestamp, kept as published. The service alerts feed's header is Adelaide local time |
| written as if it were UTC (10.5 hours ahead during daylight saving; seen 2026-10-11 and measured again 2026-10-23), while the |
| other two feeds are in true UTC. So since 2026-10-23 every row also has `ingested_at`, the UTC time this pipeline fetched the |
| feed, and the day file is taken from `ingested_at`: **use `ingested_at` for alerts.** Earlier alert files were named by the |
| shifted header, so an alert day file before 2026-10-23 can hold the evening of the day before. |
| |
| The bucket keeps the current month (plus the previous one until it is archived). **The full history is on Kaggle**, one |
| dataset per feed and month, never changed once created: `helenkwok/sa-transit-vehicles-YYYY-MM`, |
| `helenkwok/sa-transit-trip-updates-YYYY-MM` and `helenkwok/sa-transit-alerts-YYYY-MM` |
| (e.g. https://www.kaggle.com/datasets/helenkwok/sa-transit-vehicles-2026-10). |
| |
| `manifest.json` lists every file's sha256, the counts and the sources of the latest bake. Coordinates are WGS 84 as |
| published in the feed. |
