Python tools

Geographic information

• Entur GTFS to GeoParquet Python script to download Entur GTFS and convert to (Geo)Parquet. Run with uv run python/entur_gtfs_to_geoparquet.py.
• AIS to single day feather Python script to download hugging face AIS data for one day and save as arrow (feather). Run with uv run python/fetch_ais_to_arrow.py
• Estimate Vehicle Positions (DuckDB) Python script to estimate real-time vehicle positions from SIRI ET data using DuckDB for interpolation. Run with uv run python/estimate_vehicle_positions_duckdb.py.

Entur pipelines

• Entur fetch Estimated Timetable into duckdb Fetch real time Estimated Timetable data from Entur and store in duckdb table (both EstimatedCalls and RecordedCalls) uv run python/fetch_et_to_duckdb.py --dataset-id=RUT
• Entur interpolate Estimated Timetable between stop pointsFinds where vehicle by interpolating between last and next stop. Uses straight line between stops. (uv run python/interpolate_vehicle_positions.py)

Backend

FastAPI backend Simple backend for services needing that. Currently serving Entur interpolated vehicle positions.
