The World Roads Portal

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.

There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads.

The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. (Full article...)

Selected article

The Central Motorway Junction or CMJ, best known as Spaghetti Junction, is the intersection of New Zealand State Highways 1 and 16 south of the city centre of Auckland City, Auckland, New Zealand. It is multilevel structure (at least three traffic lanes crossing above each other in several locations) which has been described as a "fiendishly complicated, multi-layered puzzle of concrete, steel and asphalt" which carries around 200,000 vehicles a day.

The central motorway junction forms the intersection between the three major motorways of Auckland (Auckland Northern Motorway (1), Auckland Southern Motorway (1), and Northwest Motorway (16)), and provides access from these routes to the city centre. It is principally located in a series of gullies to the south and east of the CBD and in cuttings to the west.

Image 7Car 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)
