TranStar's `dir` field is the side of the freeway a camera sits on, not the way it faces. TranStar's own map script (translateCameraDirection) shows it as "Traffic closest to the camera is traveling": South is eastbound, North westbound, West southbound and anything else northbound. The live catalog agrees: I-10 cameras are North/South and I-45 cameras East/West. Treating `dir` as a high-confidence facing pointed most Houston cameras across or away from the road they watch, and dropped the "estimated" marking. Map it to the travel direction instead (S 90, N 270, W 180, E 0) as a low-confidence prior with the low-confidence pose, and keep the id-hash fallback for None or unknown values.
