STRIDE-QA Dataset

📦 Dataset

STRIDE-QA is a large-scale visual question answering (VQA) dataset for physically grounded spatiotemporal reasoning in autonomous driving. Constructed from 100 hours of multi-sensor driving data in Tokyo, it offers 16 M QA pairs over 270 K frames with dense annotations including 3D bounding boxes, segmentation masks, and multi-object tracks.

Category	Description
Object-centric Spatial QA	Spatial relations between two surrounding agents (single frame). Includes qualitative (e.g., relative position) and quantitative (e.g., distance, angle) questions.
Ego-centric Spatial QA	Spatial relations between the ego vehicle and a surrounding agent (single frame). Covers distance, direction, and size comparisons.
Ego-centric Spatiotemporal QA	Short-term prediction using 4 context frames (2 Hz). Forecasts distance, heading angle, and velocity at t ∈ {1, 2, 3} s.

QA Category	Qualitative (train)	Qualitative (val)	Quantitative (train)	Quantitative (val)	Total (M)
Object-centric Spatial QA	2.20	0.11	1.10	0.06	3.47
Ego-centric Spatial QA	3.10	0.16	4.33	0.23	7.82
Ego-centric Spatiotemporal QA	–	–	4.73	0.40	5.13
Total	5.30	0.28	10.17	0.69	16.43

Data Fields

The dataset is provided in .jsonl.gz. Each line in the JSONL file represents a single sample with the following fields:

Field	Type	Description
id	str	Unique sample ID.
split	str	Dataset split (train or val).
category	str	QA category type.
image	str	File name of the key frame used in the prompt.
images	list[str]	File names for the four consecutive image frames. Only available in Ego-centric Spatiotemporal QA category.
conversations	list[dict]	Dialogue in VILA format ("from": "human" / "gpt").
image_info	dict	Image metadata (height, width, dataset, landmark, file_path).
token_info	dict	Sample and sample data tokens for nuScenes reference.
qa_info	list[dict]	Metadata for each QA turn (type, category, class, token).
bbox	list[list[float]]	Bounding boxes [x₁, y₁, x₂, y₂] for referenced regions.
rle	list[dict]	COCO-style run-length masks for regions.
region	list[list[int]]	Region tags mentioned in the prompt.
