Transport in Tanzania includes road, rail, air and maritime networks. The road network is 86,472 kilometres (53,731 mi) long, of which 12,786 kilometres (7,945 mi) is classified as trunk road and 21,105 kilometres (13,114 mi) as regional road. The rail network consists of 3,682 kilometres (2,288 mi) of track. Commuter rail service is in Dar es Salaam only. There are 28 airports, with Julius Nyerere International being the largest and the busiest. Ferries connect Mainland Tanzania with the islands of Zanzibar. Several other ferries are active on the countries' rivers and lakes.
The island of Ireland, comprising Northern Ireland and the Republic of Ireland, has an extensive network of tens of thousands of kilometres of public roads, usually surfaced. These roads have been developed and modernised over centuries, from trackways suitable only for walkers and horses, to surfaced roads including modern motorways. Driving is on the left-hand side of the road. The major routes were established before Irish independence and consequently take little cognisance of the border other than a change of identification number and street furniture. Northern Ireland has had motorways since 1962, and has a well-developed network of primary, secondary and local routes. The Republic started work on its motorway network in the early 1980s; and historically, the road network there was once somewhat less well developed. However, the Celtic Tiger economic boom and an influx of European Union structural funding, saw national roads and regional roads in the Republic come up to international standard quite quickly. In the mid-1990s, for example, the Republic went from having only a few short sections of motorway to a network of motorways, dual carriageways and other improvements on most major routes as part of a National Development Plan. Road construction in Northern Ireland now tends to proceed at a slower pace than in the Republic, although a number of important bypasses and upgrades to dual carriageway have recently been completed or are about to begin.

Georgia's road network plays an important role in both domestic and international traffic with the four neighboring countries. This is expressed in the road numbering system. The country has a network of 13 internationally oriented trunk highways that connect the capital Tbilisi, home to about a third of the national population, with its four neighboring countries. This is also the backbone of a network of domestic oriented national roads connecting vital regions with each other.
In South Africa some roads are designated as numbered routes to help with navigation. There is a nationwide numbering scheme consisting of national, provincial and regional routes, and within various urban areas there are schemes of metropolitan route numbering.
Provincial routes are the second category of road in the South African route-numbering scheme. They are designated with the letter "R" followed by a number from 21 to 82, formerly with the letter "P" followed by a number from 66. They serve as feeders to the national routes and as trunk roads in areas where there is no national route.
