tomtom-flow-austin-12-935-1686.pbf — one real TomTom traffic-flow vector
tile (Mapbox Vector Tile protobuf, layer "Traffic flow"), downtown Austin
z12 x935 y1686, captured 2026-07-16 from
api.tomtom.com/traffic/map/4/tile/flow/relative/12/935/1686.pbf
(22,980 bytes). Used by offline decode/source tests and the explicit qa-traffic --fixtures
browser mode — it is a point-in-time congestion snapshot, not a bundled
data layer, and is never loaded by ordinary application startup. © TomTom.

adsb-austin-frames.txt — 112 raw Mode S frames (*<hex>;, one per line,
in receive order) received over Austin, TX, and
adsb-austin-dump1090-aircraft.json — dump1090-fa's aircraft.json decode
of the same frames, trimmed to the fields the tests assert on. Used by the
Local ADS-B decoder and record-adapter tests; never loaded at runtime.
-
adsb-austin-capture-timed.json — a second ~90 s receive over Austin, TX:
846 extended squitters from six aircraft (frames: [ms, hex]), with
dump1090-fa's decoded positions and emitter categories for the same
interval (dump1090: per ICAO flight, category and fixes as
[ms, lat, lon]). The capture has no per-frame timestamps; each frame's
time is interpolated between the frames whose decoded position equals a
dump1090 fix, timed as dump1090's now − seen_pos. Used by the decoder's
category, speed-check and track-accuracy tests; never loaded at runtime.
