Name of collection/source Name of collection/sourceThe survey used for this exercise is the "Trends in the Transport Sector".
Data source(s) used Data source(s) usedThe International Transport Forum collects data on transport statistics on annual basis from all its Member countries. Data are collected from Transport Ministries, statistical offices and other institution designated as official data source.
Data Characteristics Data Characteristics Link to Release calendar Link to Release calendarData are collected in July and made available on the ITF web site towards the end of the year.
Reference period Reference periodData series start in 1970 until the most recent available data which normally refers to the current year-1.
Variables collected Variables collectedVariables collected are inland transport of goods (T-km), of passengers (P-km) and road injury accidents. Additional information is also gathered on containers transported by rail and sea (Tons and TEU) as well as short sea shipping data (T-km).
Population & Scope Population & Scope Geographic coverage Geographic coverageThe geographical area covered is the ITF member countries.
Concepts & Classifications Concepts & Classifications Key statistical concept Key statistical conceptAlthough there are clear definitions for all the terms used in this survey, countries might have different methodologies to calculate tonne-kilometre and passenger-kilometres. Methods could be based on traffic or mobility surveys, use very different sampling methods and estimating techniques which could affect the comparability of their statistics. Also, if the definition on road fatalities is very clear and well applied by most countries, this is not the case for road injuries. Indeed, not only countries might have different definitions but the important underreporting of road injuries in most countries can distort analysis based on these data.
