Data source(s) used Data source(s) usedThe International Transport Forum collects, on a quarterly basis, monthly data from all its Member countries. When monthly information is not available then quarterly data are provided. The survey contains a dozen variables selected for their quarterly availability among reporting countries. Data are collected from Transport Ministries, statistical offices and other institution designated as official data source.
Name of collection/source Name of collection/source The survey used for this exercise is the ITF "Quarterly Transport Statistics".
Data Characteristics Data Characteristics Variables collected Variables collectedVariables collected are rail, road and inland waterways goods transport (T-km), rail passengers (P-km), road traffic (V-km), first registration of brand new vehicles, petrol deliveries to the road transport sector and road fatalities.
Link to Release calendar Link to Release calendarData are collected with a lag of 2 months and made available on the ITF web site at the end of each quarter. In May each year the four quarter of the previous year are put together to provide annual figures and produce the ITF "Key Transport Statistics Leaflet".
Other data characteristics Other data characteristicsData series start in 1994 until the most recent available data which normally refers to the current quarter-1.
Population & Scope Population & Scope Geographic coverage Geographic coverage The 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 gather or estimate quarterly data. The information provided in short-term surveys does not necessarily have the same coverage as annual data exercises and therefore remains provisional. Depending on countries, data are not always revised so totals might not correspond to the sum of the elements. The main purpose of this data collection is to identify in advance changes in transport data trends.
Transformations TransformationsIn case of missing data for a country, ITF can calculate estimates based generally on growth rates from previous years or from data available from other sources. These estimates are used solely to calculate aggregated trends in graphic representations and are not shown at the individual country level.
