![Detection results on sample videos][1] **Detection results on sample videos** The HELMET dataset contains 910 videoclips of motorcycle traffic, recorded at 12 observation sites in Myanmar in 2016. Each videoclip has a duration of 10 seconds, recorded with a framerate of 10fps and a resolution of 1920x1080. The dataset contains 10,006 individual motorcycles, surpassing the number of motorcycles available in existing datasets. Each motorcycle in the 91,000 annotated frames of the dataset is annotated with a bounding box, and rider number per motorcycle as well as position specific helmet use data is available. The structure for rider position annotation is depicted in the following Figure.  **Rider position encoding in the HELMET dataset** [1]: https://files.osf.io/v1/resources/4pwj8/providers/osfstorage/5f53707cdf5dbc00ab14303d?mode=render
