A road is a thoroughfare used primarily for movement of traffic. Roads differ from streets, whose primary use is local access. They also differ from stroads, which combine the features of streets and roads. Most modern roads are paved.
The words "road" and "street" are commonly considered to be interchangeable, but the distinction is important in urban design.
Motorway is a term for both a type of road and a classification or designation. Motorways are high capacity roads designed to carry fast motor traffic safely. In the United Kingdom they are predominantly dual-carriageway roads, with a minimum of two lanes in each direction (typically three, and up to six on the Western section of the M25), and all have grade-separatedaccess, comparable with North Americanfreeways as a road type, and interstates as a classification.
In English-speaking countries the term is used in the United Kingdom (a motorway is also called a traffordd (plural: traffyrdd) in Welsh), parts of Australia, New Zealand, Pakistan, some other Commonwealth nations, and Ireland (a motorway is also called a mótarbhealach (plural: mótarbhealaí) in Irish). In Ireland, a road built to motorway standard, but without the designation (and the regulations and traffic restrictions resulting from that designation), is known as a High-quality dual carriageway.

Image 23A patched road rut at a PortlandOregon bus stop. During the summer this part of the road will be hot and combined with a bus’s high ground pressure will compress and deform part of the road. Due to the lower elevation from the driveway, a large portion of the buses weight leans on one wheel causing damage to the road. Despite the repairs, you can see the patch is already damaged. This is all happens yearly. (from Road surface)

Image 42Car 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)
