A road is a thoroughfare for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, whose primary function is to serve as public spaces, the main function of roads is transportation.
The Trans-Canada Highway is a federal-provincial highway system that joins all ten provinces of Canada. It is, after the Trans-Siberian Highway and Australia's Highway 1, the world's longest national highway, with the main route spanning 7,821 km. The system was approved by the Trans-Canada Highway Act of 1948, construction commenced in 1950, officially opened in 1962, and was completed in 1971. The highway system is recognizable by its distinctive white-on-green maple leaf route markers.
Throughout much of Canada, there are at least two routes designated as part of the Trans-Canada Highway. For example, in the western provinces, both the main Trans-Canada route and the Yellowhead Highway are part of the Trans-Canada system.

Image 29According to Eurostat, there is almost a linear proportion between the total number of passenger-km driven by car and road fatalities. (from Road traffic safety)
Image 38Car fatalities per pax-km vs. car usage per pax-day; in Europe. It seems, at least in these European countries, that car fatalities per person-km have no strong correlation with massification of car usage. The average car usage in these countries is around 30km per person-day with varying number of fatalities ratios. These differences might be related with different cultural approaches to traffic codes, or more safety measures implemented on such countries. (from Road traffic safety)
