About a quarter of the world drives on the left, and the countries that do are mostly old Britishcolonies. The following is a list of countries of the world and the side of the road the inhabitants drive on. Most of the people driving on the left side of the road use right-hand-drive vehicles and vice-versa.
the 1999 maritime delimitation established partial maritime boundaries with East Timor over part of the Timor Gap but temporary resource-sharing agreements over an unreconciled area grant Australia 90% share of exploited gas reserves and hamper creation of a southern maritime boundary with Indonesia (see Ashmore and Cartier Islands disputes); Australia asserts a territorial claim to Antarctica and to its continental shelf (see Antarctica)
Merchant marine may be defined as all ships engaged in the carriage of goods; or all commercial vessels (as opposed to all nonmilitary ships), which excludes tugs, fishing vessels, offshore oil rigs, etc. This entry contains information in four fields - total, ships by type, foreign-owned, and registered in other countries. Total includes the number of ships (1,000 GRT or over), total DWT for those ships, and total GRT for those ships. DWT or dead weight tonnage is the total weight of cargo, plus bunkers, stores, etc., that a ship can carry when immersed to the appropriate load line. GRT or gross register tonnage is a figure obtained by measuring the entire sheltered volume of a ship available for cargo and passengers and converting it to tons on the basis of 100 cubic feet per ton; there is no stable relationship between GRT and DWT. Ships by type includes a listing of barge carriers, bulk cargo ships, cargo ships, chemical tankers, combination bulk carriers, combination ore/oil carriers, container ships, liquefied gas tankers, livestock carriers, multifunctional large-load carriers, petroleum tankers, passenger ships, passenger/cargo ships, railcar carriers, refrigerated cargo ships, roll-on/roll-off cargo ships, short-sea passenger ships, specialized tankers, and vehicle carriers. Foreign-owned are ships that fly the flag of one country but belong to owners in another. Registered in other countries are ships that belong to owners in one country but fly the flag of another.
The major ports and harbors selected on the basis of overall importance to each country. This is determined by evaluating a number of factors (e.g., dollar value of goods handled, gross tonnage, facilities, and military significance).

This entry lists major ports and terminals primarily on the basis of the amount of cargo tonnage shipped through the facilities on an annual basis. In some instances, the number of containers handled or ship visits were also considered.
Paved roads are those surfaced with crushed stone (macadam) and hydrocarbon binder or bituminized agents, with concrete, or with cobblestones, as a percentage of all the country's roads, measured in length."
