π Indian Road Driving Dataset
The Indian Road Driving Dataset is the largest open dataset of annotated Indian road footage, created by ThirdEye Labs. It addresses the critical gap in autonomous driving datasets for Indian road conditions.
π Why Indian Roads?
Indian roads present unique challenges absent from existing datasets (BDD100K, nuScenes, Waymo):
- Dense mixed traffic with unpredictable behavior
- Auto-rickshaws, cattle, and informal lane usage
- Extreme lighting conditions
- 63 million vehicles and 1.4 billion people, yet no large-scale annotated dataset existed
π Dataset Statistics
| Metric | Value |
|---|---|
| Total clips | 8,437 |
| Annotated frames | 645,714 |
| Object detections | 3,669,119 (with ByteTrack IDs) |
| Segmentation masks | 1,290,463 |
| GPS-tagged frames | β |
| Annotation format | BDD100K |
| Label provenance | Machine-generated, not human-verified |
| Sensor | Monocular camera + per-clip GPS (no LiDAR/radar/IMU) |
| Capture device | CP Plus dashcam |
| Location | Delhi NCR, India |
| Conditions | Day Β· Night Β· Dusk Β· Rain |
β οΈ How these labels were produced
Labels are machine-generated and have not been human-verified. The export
writes manualShape: false on every box, which BDD100K defines as machine
annotation. Models used:
| Stage | Model |
|---|---|
| Detection | YOLO11m fine-tuned on IDD |
| Tracking | ByteTrack |
| Segmentation | SegFormer-B5 fine-tuned on IDD |
| Scene attributes | CLIP ViT-L/14 |
Two consequences worth stating plainly:
- Treat this as a large pseudo-labelled corpus, not gold ground truth. About 33% of detections fall below 0.5 confidence.
- Do not benchmark detectors against these labels and call it accuracy. The labels come from IDD-fine-tuned models, so disagreement measures domain gap between label source and model under test, not correctness.
A human-verified evaluation split is in progress.
π Class coverage finding
Three of the 12 classes (autorickshaw, animal, vehicle fallback) have no
equivalent in the BDD100K label set, so a detector trained on BDD100K cannot
emit them at all.
| Slice | Share of detections in unrepresentable classes |
|---|---|
| Overall | 9.42% |
| Night | 13.91% |
| Foggy | 15.82% |
| Highway | 11.10% |
| Clear daytime | 8.57% |
Auto-rickshaws alone account for 185,383 detections (5.05%) and appear in 6,775 of 8,437 clips (80.3%).
Counts computed directly from annotations/detection.json.
π·οΈ Detection Classes (12 classes)
- person: Pedestrians
- rider: Motorcyclists/cyclists with rider
- car: Passenger cars
- truck: Trucks and tempos
- bus: Buses
- motorcycle: Motorcycles (unridden)
- bicycle: Bicycles
- autorickshaw: Auto-rickshaws (tuk-tuks)
- animal: Cattle, dogs, animals on road
- vehicle fallback: Unclassified vehicles
- traffic light: Traffic signals
- traffic sign: Road signs and boards
π Dataset Structure
Data is stored as 646 WebDataset tar shards (data/train-00000-of-00646.tar β¦ data/train-00645-of-00646.tar), each containing ~1,000 frames. Each frame has 3 files inside the shard:
{clip_id}_{frame:04d}.jpg # keyframe image
{clip_id}_{frame:04d}.png # segmentation mask
{clip_id}_{frame:04d}.json # BDD100K annotations (detections + scene attributes)
Standalone annotation files are also provided for convenient bulk access:
annotations/
βββ detection.json # BDD100K format, all 645,714 frames (1.2 GB)
βββ scene_attributes.json # per-clip weather, time of day, scene type
gps/
βββ gps_tracks.json # GPS coordinates per clip
π Quick Start
Load with π€ Datasets
from datasets import load_dataset
ds = load_dataset("thirdeyelabs/indian-road-dataset")
sample = ds["train"][0]
# sample keys: jpg, png, json
Load annotations directly
import json
with open("annotations/detection.json") as f:
annotations = json.load(f)
# BDD100K format, each entry:
# { "name": "clip_id/frame", "labels": [{ "category": "car", "box2d": {...} }] }

πΊοΈ GPS Coverage
About two-thirds of clips include per-second GPS with speed and heading, enabling:
- Geographic filtering by route/area
- Speed and trajectory analysis
- Map-based dataset exploration
ποΈ Production Pipeline
ThirdEye Labs end-to-end ML annotation system:
- Ingest: raw MP4s from CP Plus dashcams to S3
- Keyframe extraction: 1 frame/second via FFmpeg
- GPS parsing: matched from
.srtfiles - Object detection: custom YOLO fine-tuned for Indian roads
- Semantic segmentation: SegFormer for drivable areas
- Multi-object tracking: ByteTrack across frames
- Scene classification: weather, lighting, scene type
