I'm building a traffic-noise model of the Gürtel corridor for the City of Vienna and need the surrounding network as a single GeoPackage. Can you pull every highway from the current Geofabrik Austria PBF (https://download.geofabrik.de/europe/austria-latest.osm.pbf) that intersects a 500 m buffer around Vienna's Gürtel, defined as the highway ways whose name ends in 'Gürtel'? I also need every public-transport route relation (bus, tram, subway, train, trolleybus, light_rail) that crosses the same buffer, with each route as a single feature. Keep the OSM attributes full and untruncated: name, highway, maxspeed, lanes, surface, and oneway on highways; ref, name, operator, and route on the PT routes. Please write both layers to vienna_network.gpkg, with the highways layer as LineString and the pt_routes layer as MultiLineString, in Austria's standard projected coordinate system.
