**Which TTC to use? Cross-reference the second TRB paper. There will be overlap on that content**  \subsubsection{Gap acceptance & Yielding Behaviour}  \subsection{Site Selection}  Site selection was performed according to a number of criteria including practical constraints and statisitical representation. Data collection feasability was scored on a five-point scale measuring data collection cost and quality and sorted to generate a feasibility rank. Among a population of nearly one hundred candidate roundabouts in the province of Québec, starting from the most feasible, thirty sites were chosen to provide a good representation of design and land use characteristics, knowing that a fraction of these sites would have to be rejected due to logistical issues (e.g. adverse weather, road closures, or equipment failure hampering data collection efforts). In particular:  \begin{itemize}  \item An adequate geographical coverage of the province of Québec and land use representation was desired. Sites were selected throughout all but one of the the major populated regions of Québec, as well as some of the more rural areas to provide regional representation. As listed in Table~\ref{tab:be_fac}, representation of the built environment factors is adequate though with a few exceptions. Notably, roundabouts on private roads are difficult to access for data collection and provide little safety information anyways as traffic flows are too small. Also, while roundabouts can often be found in school or commercial zones, these roundabouts did not serve through-traffic, serving instead as access gentrified points for parking lots or campus roads. These sites were rejected.  \item Roundabouts located on the territory of the provincial transportation agency are all built to very similar specifications and are significantly more consistent in design than municipal roundabouts. However, provincial roundabouts tend to serve more network classes than municipal roundabouts which serve collector roads for the most part. 40\% of the sites were located on provincial territory while the remainder were strewn across seven different municipalities.  \end{itemize}
