At each Swedish roundabout, two cameras were positioned in such a way to cover the entire roundabout completely, and to cover at least one merging zone in each camera completely. The use of analysis zones as units of study instead of roundabouts as a whole is that, while many factors such as land use are shared, many more are not. This includes flows and flow ratios especially, but may also include geometric factors such as lane configuration, signalisation, presence of a crosswalk, approach angle, etc. which can vary from one merging zone to the next even within the same roundabout \cite{St_Aubin_2013}. Studying merging zones individually also better encapsulated the microscopic nature of the data being collected and analysed: roundabouts are often large enough for road user interactions on different sides of the roundabout to occur independently.  TableX  lists a summary of the sites, the analysis zones at each and the geometric and land use characteristics of each.   \begin{table}  \caption{Analysis Zones Inventory}  \label{analysis_zones}  \begin{tabular}{llllllll}  \textbf{Site} & \textbf{Land Use} & \textbf{Urban Density} & \textbf{Inside Radius} & \textbf{Outside Radius} & \textbf{Hourly Flow} & \textbf{Flow Ratio} & \textbf{Crosswalk} \\  \hline  SE-Fasanvagen-Trollebergsvagen-1 & Mixed & Medium & 18.0 & 25.0 & 274.8 veh/h/ln & & Approach \& exit \\  SE-Fasanvagen-Trollebergsvagen-2 & Mixed & Medium & 18.0 & 25.0 & 241.3 veh/h/ln & & Approach \& exit \\  SE-R103-Foretagsvagen-1 & Commercial & Very low & 15.0 & 22.0 & 237.3 veh/h/ln & & Approach \\  SE-R103-Foretagsvagen-2 & Commercial & Very low & 15.0 & 22.0 & 182.2 veh/h/ln & & None \\  SE-RubenRausings-Borgs-1 & Mixed & Low & 13.5 & 22.0 & 115.9 veh/h/ln & & Approach \& exit \\  SE-RubenRausings-Borgs-2 & Mixed & Low & 13.5 & 22.0 & 82.0 veh/h/ln & & Approach \& exit \\  SE-Svenshogs-NorraGrans-1 & Suburban residential & Low & 7.5 & 16.5 & 119.0 veh/h/ln & & Approach \& exit \\  SE-Svenshogs-NorraGrans-2 & Suburban residential & Low & 7.5 & 16.5 & 176.9 veh/h/ln & & Approach \& exit \\  & & & & & & &   \end{tabular}  \end{table}
