# Cyclist Behavior 2D Keypoints V5

Version 2.0.0 is a complete replacement of the earlier intersection release. It contains
de-identified cyclist skeleton scene clips for bus-stop/road behavior prediction.

## Summary

- 32 participants, 559 scene clips, 99,734 frames
- 33 two-dimensional pose landmarks (66 coordinates)
- Stage1 labels: head look, upper-limb rotation, and pedaling intervals
- Stage2 labels: `straight`, `yield`, and `overtake`
- canonical Fold 1 participant-disjoint train/validation/test split
- all five participant folds in `participant_folds.parquet`

| Split | Sequences | Frames |
|---|---:|---:|
| Train | 369 | 65,235 |
| Validation | 103 | 18,491 |
| Test | 87 | 16,008 |

`annotations.parquet` contains sanitized Stage1 gesture intervals and exclusion flags.
`sequences.csv` contains clip-level maneuver labels, route anchors, FPS, and Stage2 eligibility.

## Privacy

Raw video, original filenames, calendar dates, session IDs, direct participant numbers,
and source paths are excluded. Release-scoped HMAC identifiers preserve grouping without
publishing the source mapping. Pose trajectories can retain behavioral signatures; users
must not attempt re-identification or linkage with external identity data.

## Intended use and limitations

Intended for cyclist behavior, temporal pose, and participant-independent evaluation research.
The simulator domain and variable source frame rate (12.690–19.423 FPS)
limit direct real-world generalization. This dataset must not be used for biometric identification,
surveillance, or safety-critical control without independent validation.
