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 A4232, which is known either as the Peripheral Distributor Road (PDR) (Welsh: Ffordd Ddosbarthu Ymylol) or the Cardiff Link Road (Welsh: Ffordd Gyswllt Caerdydd), is a distributor road in Cardiff, the capital of Wales.
The first section of the PDR to be completed was the Southern Way Link Road between Newport Road (A4161 road) and the Eastern Avenue (A48 road) in 1978.rem When fully completed, the road will form part of the Cardiffring-road system. The PDR runs west, south and east of Cardiff, with the M4 between junction 30 and junction 33 completing the northern section. The PDR is dual carriageway for its entire length except for the East Moors Viaduct, which is a single carriageway.

Image 34Car 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)
