Since cyclists are highly sensitive to road surface conditions and hazards they require more detailed information when navigating their route. To facilitate a better understanding of what causes hazardous conditions to cyclists we created a dataset of classified hazardous cycling conditions. Egocentric cycling footage and IMU data was collected in Hong Kong and Australia on various types of cycling infrastructure using sensors attached to the cyclist. By collecting both video and IMU data we were able to identify moments where the cyclist was experiencing sudden braking or uncomfortable cycling conditions as indicated by the IMU. We then extracted videos from these moments and classified them using Amazon Mechanical Turk. This project was sponsored by Amazon and was created for the EPIC @ CVPR 2020 Dataset challenge.
