A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation.
The following are images from various road-related articles on Wikipedia.

Image 3Car 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)
