Roadwork Cones Dataset

This dataset is designed for detecting roadwork-zone objects in autonomous driving scenarios. It contains three classes - traffic cones, roadworks signs, and vertical guide panels (delineators) - captured from four vehicle-mounted cameras across 39 driving sessions in urban and suburban roads.

Dataset Description

—Source: Fleet of autonomous vehicles, urban and suburban roads
—Sensor: 4x LUCID TRI054S-CC cameras (2880×1860), front/side facing
—Coverage: ~31K bounding box annotations, ~4.7K unique images, 3 classes
—Splits: Train 70% (22,841 rows, 2,871 images), Test 30% (8,561 rows, 1,803 images) - split by driving session to prevent temporal leakage
—Format: Parquet (annotations) + JPEG (images) in train/ and test/ subdirectories
