YOLO26s Finetuned on RDD2022 Road Damage

Fine-tuned YOLO26s object detector on the RDD2022 Road Damage benchmark dataset, trained and evaluated as part of DetectionBench -- a framework for reproducibly benchmarking modern object detectors with identical training recipes and evaluation metrics across multiple real-world datasets.

Training Framework

This model was trained using DetectionBench, an open-source framework for benchmarking object detectors across multiple real-world datasets with a common pipeline.

Features include:

• A dataset-adapter registry for converting real-world datasets into a canonical format
• Identical training/evaluation recipes across model families (Ultralytics YOLO/RT-DETR, RF-DETR)
• Hardware profiling (latency, FPS, VRAM, parameters, FLOPs)
• One-command reproducibility via versioned Hydra configs

Known Limitations

• Not comparable to the official CRDDC2022 leaderboard: the challenge test set has no public labels, so the test split here is a held-out 15% slice (70/15/15 split) of the publicly-labelled images, merged across countries -- scores are only comparable between the models listed in this card's Model Zoo.
• Class imbalance: longitudinal_crack (44.0%) is the most common class, while pothole (18.1%) and alligator_crack (17.9%) are the rarest of the four -- per-class accuracy differs noticeably between them.
• Four-class taxonomy only: the source data's 5th "other" bucket (block cracks, road repairs and country-specific codes, ~6.5k boxes) was dropped to match the four damage types the CRDDC2022 challenge scores, so those damage types are not detected.
• Sparse, thin targets: about a third of images contain no in-taxonomy damage (clean-road frames), with 1.5 boxes per image on average, and cracks are thin structures that are easily lost when large frames (some over 4000 pixels wide) are downscaled to the model's input size.
• Uneven country and imaging-setup mix: the images come from six countries and several capture setups (smartphone, dashboard camera, drone) in very different proportions, so performance can vary substantially by country and generalization to unseen regions or damage conventions is untested.
• Share-alike data: the RDD2022 images are CC BY-SA 4.0 -- see the Dataset section above for attribution and the dataset card for the full terms.
