\section{Introduction}  As high-income countries, Canada and Sweden especially are among some of the safest countries in the world to operate a motor vehicle in. Despite this, annual traffic fatality rates in Canada are nearly twice as high as in Sweden, as measured per 100,000 inhabitants, per 100,000 registered motor vehicles, and per billion veh-km traveled \cite{WHO_2013}, \cite{WHO_2013, OECD_2015},  and this despite relatively comparable car occupant mode share. share \cite{OECD_2015}, comparable design of some infrastructure elements and similar climactic conditions.  This paper examines  Education aims to collect  and enforcement are two compare individual measures of driver behaviour and driving culture indicative  ofthe three long-standing traffic safety design tenets in  road safety circles today, along with engineering. However, unlike engineering, issues  which is implemented in large part at might capture  the individual site level, education and enforcement programs are typically implemented at the national and sub national levels. It thus follows that distinct, yet so disparity in road safety.  Roundabouts might arguably be one of the best types of road infrastructure for direct comparison of road user behaviour and driving culture between North America and Europe. Although a relatively new phenomenon in North America, roundabouts are one of the few types of road designs with near identical geometric and aesthetic features in both North America and Europe. This is not surprising as the North American roundabout design is heavily influenced by European roundabout design. Incidentally, the European roundabouts studied in this paper are relatively new compared to other areas of Europe and the comparable Québec roundabouts are at least ten years old.
