Transport Stats: compare key data on Japan & Western Sahara
Definitions
- Airports: Total number of airports. Runways must be useable, but may be unpaved. May not have facilities for refuelling, maintenance, or air traffic control.
- Airports > Per capita: Total number of airports. Runways must be useable, but may be unpaved. May not have facilities for refuelling, maintenance, or air traffic control. Per capita figures expressed per 1 million population.
- Airports > With paved runways > Total: Total number of airports with paved runways (concrete or asphalt surfaces)
- Airports > With paved runways > Total > Per capita: Total number of airports with paved runways (concrete or asphalt surfaces) Per capita figures expressed per 1 million population.
- Airports > With unpaved runways > 914 to 1,523 m: This entry is derived from Transport > Airports > With unpaved runways, which gives the total number of airports with unpaved runways (grass, dirt, sand, or gravel surfaces) by length. For airports with more than one runway, only the longest runway is included according to the following five groups - (1) over 3,047 m (over 10,000 ft), (2) 2,438 to 3,047 m (8,000 to 10,000 ft), (3) 1,524 to 2,437 m (5,000 to 8,000 ft), (4) 914 to 1,523 m (3,000 to 5,000 ft), and (5) under 914 m (under 3,000 ft). Only airports with usable runways are included in this listing. Not all airports have facilities for refueling, maintenance, or air traffic control. The type aircraft capable of operating from a runway of a given length is dependent upon a number of factors including elevation of the runway, runway gradient, average maximum daily temperature at the airport, engine types, flap settings, and take-off weight of the aircraft.
- Airports > With unpaved runways > Total: Total number of airports with useable unpaved runways (grass, dirt, sand, or gravel surfaces)
- Highways > Paved: total length of the paved parts of the highway system
- Highways > Paved > Per capita: total length of the paved parts of the highway system Per capita figures expressed per 1,000 population.
- Highways > Total: total length of the highway system
- Highways > Total > Per capita: total length of the highway system Per capita figures expressed per 1,000 population.
- Ports and harbors: 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).
- Ports and terminals: 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.
- Rail > Railway length: Railway length in kilometers.
- Roadways > Total: This entry gives the total length of the road network and includes the length of the paved and unpaved portions.
- Roadways > Unpaved: This entry gives the total length of the road network and includes the length of the paved and unpaved portions.
- Highways > Unpaved: total length of the unpaved parts of the highway system
- Highways > Unpaved > Per capita: total length of the unpaved parts of the highway system Per capita figures expressed per 1,000 population.
- Airports > With paved runways > 2438 to 3047 m > Per capita: Number of airports with paved runways (concrete or asphalt surfaces), categorised according to the length of the longest runway Per capita figures expressed per 1 million population.
- Airports > With unpaved runways > 1,524 to 2,437 m: This entry is derived from Transport > Airports > With unpaved runways, which gives the total number of airports with unpaved runways (grass, dirt, sand, or gravel surfaces) by length. For airports with more than one runway, only the longest runway is included according to the following five groups - (1) over 3,047 m (over 10,000 ft), (2) 2,438 to 3,047 m (8,000 to 10,000 ft), (3) 1,524 to 2,437 m (5,000 to 8,000 ft), (4) 914 to 1,523 m (3,000 to 5,000 ft), and (5) under 914 m (under 3,000 ft). Only airports with usable runways are included in this listing. Not all airports have facilities for refueling, maintenance, or air traffic control. The type aircraft capable of operating from a runway of a given length is dependent upon a number of factors including elevation of the runway, runway gradient, average maximum daily temperature at the airport, engine types, flap settings, and take-off weight of the aircraft.
