- 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)

Based on 0-50 contributions for Argentina, Armenia, Austria and 63 more countries and 50-100 contributions for Australia, Brazil, Germany and 5 more countries and over 100 contributions for Canada, India, and United States. The surveys were conducted by numbeo.com from January, 2011 to February, 2014. See this sample survey for the United States, respondents were asked "Distance".
- Inefficiency index: Each country's inefficiency rating in regards to traffic. Long commute times, poor traffic laws and other factors are taken into consideration.
- Motor vehicles > Per 1,000 people: Motor vehicles include cars, buses, and freight vehicles but do not include two-wheelers. Population refers to midyear population in the year for which data are available."

- Road network length > Km: Length of road network in kilometers in European Union countries.
- Roads > Traffic index: Traffic Index is a composite index of time consumed in traffic due to job commute, estimation of time consumption dissatisfaction, CO2 consumption estimation in traffic and overall inefficiencies in the traffic system.
- Roadways > Unpaved: This entry gives the total length of the road network and includes the length of the paved and unpaved portions.
- Waterways: The total length and individual names of navigable rivers, canals, and other inland bodies of water.
