|
|
| This dataset contains driving recorded in CARLA under three explicit style instructions, **normal (neutral)**, **aggressive** and **conservative**. It forms the per-style retrieval databases and the style fine-tuning data of [PersonaDrive](https://huggingface.co/PervasiveAutonomyLab/PersonaDrive). |
|
|
| PersonaDrive retrieves frames of the selected style as in-context demonstrations, so switching style only means searching a different part of this dataset. |
|
|
| > **Style names.** The folders use the code's names. |
| > - **`default` is normal, everyday driving** (the neutral instruction). |
| > - `fast` is aggressive. |
| > - `slow` is conservative. |
| > |
| > The code also has a retrieval profile called `normal`. It is not part of this dataset, because it is the style-agnostic index built from SimLingo's PDM-lite data. |
|
|
| ## At a glance |
|
|
| | Folder | Style | Frames | |
| |---|---|---:| |
| | `default` | **Neutral (normal driving)** | 9,613 | |
| | `fast` | Aggressive | 7,143 | |
| | `slow` | Conservative | 13,021 | |
| | **Total** | | **29,777** | |
|
|
| These are the frames the 15 participants drove (`driver1`–`driver15`). The `fast` and `slow` folders also contain `lb1_split`, with routes of SimLingo's Leaderboard 1.0 split recorded in the aggressive and conservative style. They are not part of the participant data and are not counted above. Stage-3 fine-tuning uses data from all three styles. |
|
|
| Each frame has a front camera image, the ego state and controls, the navigation targets and the surrounding objects. Most routes also have per-frame commentary and VQA annotations. |
|

| | File | Size | Files | Contents | |
| |---|---:|---:|---| |
| | `data_default.zip` | 2.37 GB | 19,394 | Normal (neutral) driving, with camera frames, per-frame measurements and surrounding objects. | |
| | `data_fast.zip` | 11.69 GB | 81,033 | Aggressive driving (`fast/driver*`), plus the `fast/lb1_split` fine-tuning routes with their retrieved context points (`icl_examples.json.gz`). | |

| ``` |
|
|
| **Which zips you need** |
|
|
| | Task | Zips | |
| |---|---| |
| | Use the driving data of one style | `data_<style>` (plus `commentary` / `drivelm` for language) | |
| | Evaluate PersonaDrive with a style (`default` / `fast` / `slow`) | `data_<style>` of that style | |
| | Re-run Stage-3 fine-tuning | `data_default`, `data_fast`, `data_slow`, `commentary`, `drivelm`, plus SimLingo's PDM-lite data | |
| | Re-run Stages 1–2 (retrieval head, per-style indices) | all five zips, plus PDM-lite for the style-agnostic `normal` index | |
|
|
| Evaluation with retrieval opens the camera frames of the retrieved demonstrations, so it needs the frames of the chosen style. It also needs the retrieval head, which is in the [code repository](https://github.com/PervasiveAutonomyLab/PersonaDrive/blob/main/persona_drive_rag/checkpoints/best_model.pt), and the per-style FAISS indices, which you build from this dataset ([Build the retrieval indices](https://github.com/PervasiveAutonomyLab/PersonaDrive#3-build-the-retrieval-indices)). The code repository's [`datasets/README.md`](https://github.com/PervasiveAutonomyLab/PersonaDrive/blob/main/datasets/README.md) lists which zips each use needs. |

|
| ## How the data was collected |
|
|
| <img src="assets/hardware_rig.jpg" width="45%" align="right" alt="Driver-in-the-loop rig"> |
|
|
| 15 participants drove CARLA Leaderboard routes at a driver-in-the-loop rig with a real wheel and pedals. The recording code is released with PersonaDrive ([`human_data_collection/`](https://github.com/PervasiveAutonomyLab/PersonaDrive/tree/main/human_data_collection)). Each participant drove each of their routes three times, each time under a different instruction. |
|
|
| | Folder | Style | What the driver was told | |
| |---|---|---| |
| | `default` | **Neutral (normal driving)** | *"Follow traffic laws, navigate safely, and drive at a reasonable speed."* | |
| | `fast` | Aggressive | *"Drive as fast as possible without crashing; engage in aggressive behaviors such as tailgating and cutting off merging vehicles."* | |
| | `slow` | Conservative | *"Target 10–15 mph on surface streets and 25–35 mph on the highway; yield to other vehicles whenever possible."* | |
|
|
| **Rig.** |
| - **Hardware.** A Next Level Racing GTrack bucket seat, three 50-inch monitors covering about 130° of view, and a Logitech G923 wheel and pedals. |
| - **Simulator.** CARLA 0.9.15 ran synchronously at 20 Hz. The ego vehicle was the only human-controlled actor, and CARLA's Traffic Manager populated the surrounding traffic. |
| - **Display.** A Pygame window showed the first-person view, the speed, the active navigation instruction and scenario, and a bird's-eye view of the surrounding vehicles (for manoeuvres such as merges). |
|
|
| **Protocol.** |
| - **Disjoint from evaluation.** Routes were drawn at random from the CARLA Leaderboard route sets, and none of them is a Bench2Drive evaluation route. Their scenario types also appear in Bench2Drive, so a retrieved demonstration can be relevant to an evaluation situation, but no evaluation episode is in the dataset. |
| - **Three passes.** Each participant drove each of their routes once per instruction, in randomized order, so that style is not confounded with route familiarity. |
| - **Supervision.** Participants were supervised to make sure they followed the instructions. |
| - **Anonymity.** `driver<N>` is an anonymous participant index. The same index refers to the same participant in all three styles. |
|
|
| | Style | Mean speed (mph) | In motion (mph) | Std. dev. | Stopped (%) | |
| |---|---:|---:|---:|---:| |
| | Conservative (`slow`) | 9.8 | 11.5 | 7.6 | 14.6 | |
| | Neutral, normal driving (`default`) | 13.2 | 15.6 | 10.8 | 15.7 | |
| | Aggressive (`fast`) | 17.5 | 21.8 | 16.8 | 19.8 | |
|
|
| <sub>Speed statistics computed from the recorded ego state, route-matched over the 55 routes driven under all three instructions. The instructions separate before any model is involved.</sub> |
|
|
| **What is recorded.** CARLA runs at 20 Hz and every fifth step is stored, so each route has the following at 4 Hz. |
| - The front camera image, plus a shifted-camera copy used for augmentation. |
| - The ego state from CARLA (speed, pose), which follows the participant's driving. |
| - The controls `throttle`, `steer` and `brake` in `measurements.json`. |
| - The navigation command and the next GPS target points from CARLA's route planner. |
| - The surrounding vehicles, pedestrians, traffic signs and traffic-light states. |
|
|
| ### `commentary.zip` (what the car is doing, in words) |
|
|
| - **Contents.** One sentence per frame that says what the car does and why, together with the object that causes it. An example is *"Follow the route. Accelerate to drive with the target speed."* |
| - **How it was made.** SimLingo's commentary generator produced it automatically after recording, from the recorded simulator state (route, hazards, surrounding objects). Participants did not write it. |
|
|
| ### `drivelm.zip` (questions and answers about each scene) |
|
|
| - **Contents.** Per-frame question–answer pairs about perception, prediction and planning, in the DriveLM format. An example is *Q: "What are the important objects in the scene?" A: "The important object in the scene is the black car to the front left of the ego vehicle."* |
| - **How it was made.** A DriveLM-style generator produced them automatically from the recorded objects and ego state. |

|
|
| Each route folder (`<Town..>/`) contains these files. |
|
|
| | File | Contents | |
| |---|---| |
| | `rgb/NNNN.jpg` | Front camera, one frame per dataset step (4 Hz). | |
| | `rgb_augmented/NNNN.jpg` | Shifted-camera augmentation. | |
| | `measurements.json` | Per-frame list of `speed`, `throttle`, `steer`, `brake`, `command`, `next_command`, `target_point(_next)`, `ego_matrix`, `route`, `aim_wp`, … | |
| | `boxes.json` | Per-frame surrounding objects (`driver<N>` routes). | |
| | `result.json`, `records.json.gz` | Simulator logs. | |
| | `icl_examples.json.gz` | `lb1_split` routes only. Written by Stage 3a of the code. For every frame it holds the K = 2 most similar frames retrieved from the same style's database, i.e. the demonstrations the model was fine-tuned with (`rgb_path`, `speed_history`, `throttle_history`, `command`, `target_point(_next)`, `commentary`, `waypoints`). | |
|
|
| `commentary.json` and `vqa.json` are per-frame lists aligned with `measurements.json`, and frames without an annotation are `null`. |
|
|
| ## Processing and privacy |
|
|
| - **Anonymity.** Participants are identified only by an index (`driver1`–`driver15`). The dataset contains no names or other personal information about participants. |
| - **Frame paths in annotations.** The frame paths inside `commentary.json` and `vqa.json` were rewritten to paths relative to the data root (`simlingo/data/simlingo/...`). |
| - **Paths in `icl_examples.json.gz`.** These keep the absolute paths of the machine they were built on. The PersonaDrive loader resolves both forms against `$PERSONADRIVE_DATA_ROOT`. |
| |
| ## Not included |
| |
| - **SimLingo's PDM-lite data** (`training_1_scenario` for Stage-3 fine-tuning, and `training_1_scenario`, `training_3_scenarios` and SimLingo's own `lb1_split` for the `normal` index, see the code repository's [`datasets/README.md`](https://github.com/PervasiveAutonomyLab/PersonaDrive/blob/main/datasets/README.md)). It is the SimLingo dataset of Wayve Technologies Ltd and is distributed by its authors under their own licence. Download it from [SimLingo](https://github.com/RenzKa/simlingo). |
| - **The FAISS indices and other retrieval artefacts.** Build them from this dataset with the [code repository](https://github.com/PervasiveAutonomyLab/PersonaDrive#3-build-the-retrieval-indices). |
