Analyzing such big data is a challenge of a magnitude that has never been undertaken before in road safety research. It holds the key to understanding the processes that lead road user to collide, to design and validate safety indicators that do not require to wait for accidents to occur. The approach will be demonstrated on this video dataset to identify roundabout characteristics that influence road   \subsection{Motivation}  \subsubsection{Size of data (hours, GB, framerate, resolution)}
