# Person2Drive Dataset Details

This document provides additional details about the organization, content, and release status of the Person2Drive dataset.

## Dataset Overview

Person2Drive is a closed-loop personalized end-to-end autonomous driving dataset collected in the CARLA simulator. The dataset is designed to support research on human driving style modeling, driver-level personalization, and closed-loop autonomous driving evaluation.

The dataset contains human driving records collected from anonymized drivers under controlled CARLA driving environments. Each driver is represented by an anonymized identifier, such as `driver01`, `driver02`, and so on.

## Dataset Scale

The full Person2Drive dataset contains:

* **50 anonymized human drivers**
* **4 driving routes**
* **multiple repeated drives for each driver-route setting**
* **driver-level metadata and route-level driving records**

The dataset is being progressively uploaded to this Hugging Face repository. Please refer to [`RELEASE_MANIFEST.md`](./RELEASE_MANIFEST.md) for the current upload status.

## Data Organization

The released dataset is organized by driver. Each driver folder contains compressed route-level driving record archives and a corresponding metadata file.

The current repository structure is:

```text
Person2Drive/
├── drivers/
│   ├── driver01/
│   │   ├── Town04_drive_1.tar.zst
│   │   ├── Town04_drive_2.tar.zst
│   │   ├── ...
│   │   ├── Town05_drive_8.tar.zst
│   │   └── b2d_infos_train.pkl
│   ├── driver02/
│   │   ├── Town04_drive_1.tar.zst
│   │   ├── ...
│   │   ├── Town05_drive_8.tar.zst
│   │   └── b2d_infos_train.pkl
│   └── ...
├── b2d_map_infos.pkl
├── RELEASE_MANIFEST.md
├── DATASET_DETAILS.md
└── README.md
```

Each `driverXX/` folder corresponds to one anonymized human driver.

## Route-Level Archives

The `.tar.zst` files are compressed route-level driving record packages. Each archive contains data collected from a specific driver under a specific route or driving setting in CARLA.

Examples include:

```text
Town04_drive_1.tar.zst
Town04_drive_2.tar.zst
Town05_drive_1.tar.zst
Town05_drive_2.tar.zst
```

The file names indicate the CARLA town and drive index used in the released data organization.

## Data Content

Depending on the released archive, the dataset may include:

* ego-vehicle states
* control signals, such as steering, throttle, and brake
* ego trajectories
* route and navigation information
* selected sensor data used by end-to-end driving models
* metadata for driver-level and route-level organization

The exact internal structure of each archive will be further documented as the release is completed.

## Metadata Files

Each driver folder contains a metadata file:

```text
b2d_infos_train.pkl
```

This file stores driver-specific metadata used for data loading and organization.

The root directory contains:

```text
b2d_map_infos.pkl
```

This file stores map-level metadata used by the dataset and benchmark pipeline.

## Anonymization

Driver identities are anonymized. Public driver folders use identifiers such as `driver01`, `driver02`, and so on. No real driver names are used in the released dataset structure.

## Release Status

The dataset is currently being uploaded and organized. Files already available in this Hugging Face repository are part of the public release.

The release status of uploaded and in-progress driver folders is tracked in:

```text
RELEASE_MANIFEST.md
```

## Notes

This document focuses on the dataset organization and released data files. Benchmark protocols, evaluation metrics, and code-level usage instructions will be documented separately.
