Reference metadata

Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.

Eurostat collects road transport statistics by two means:

1. Data on infrastructure, transport equipment, enterprises, economic performance, employment, traffic, aggregated data on transport of passengers and goods as well as data on accidents are collected using the Common Questionnaire of the United Nations Economic Commission for Europe (UNECE), Eurostat and the International Transport Forum (ITF, in the framework of OECD). The method of the Common Questionnaire data collection is presented in a separate document.

2. Data on carriage of goods by road, using heavy goods vehicles, are based on a continuum of legal acts:

2.1 Data collection on carriage of goods by road until 1998 (included) was based on Directives 78/546/EEC and 89/462/EEC and covered tonnes and tonne-kilometres only.

2.2 Data since the reference period 1999 are derived from micro-data collected in the framework of Regulation (EU) No 70/2012 of the European parliament and of the council on statistical returns in respect of the carriage of goods by road, a recast of Council Regulation (EC) No 1172/98 which has replaced the previous Directives. The figures are aggregated on the basis of sample surveys carried out by the reporting countries. The data cover tonnes, tonne-kilometres, vehicle-kilometres and numbers of journeys.

These metadata pages only refer to road freight statistics based on the European Union's legal acts (point 2 above) and, in particular, to the data for reference years 1999 and after (2.2).

Road freight data collection consists of three datasets for each quarter from each reporting country:

  • Vehicle information for a sample of road good motor vehicles
  • Journey information of loaded and empty (optional) journeys by the vehicles in the sample during the observation period (most often one week)
  • Goods information on loads transported during the reported journeys.

The quantity and performance of road freight transport are collected in tonnes, tonne-kilometres, vehicle-kilometres and number of journeys. Tonne-kilometres are both collected (in journey and goods datasets) and calculated (by multiplying the weight of goods by the distance travelled for each goods operation).

For the variables collected please refer to Commission Regulation (EC) No 2163/2001.

Road freight transport statistics are reported by Member States for vehicles registered in their country. On the basis of variables contained in the micro-data (reporting country, country of loading and country of unloading of a journey) five types of operations are derived:

  • National transport
  • International transport - goods loaded in the reporting country
  • International transport - goods unloaded in the reporting country
  • International transport - cross-trade
  • International transport - cabotage

Specific characteristics of each country’s data collection are provided in the country specific note which is available in CIRCABC.

The main concepts used in Road freight statistics are the following, more details can be found in the Road freight transport methodology manual : 

A goods road motor vehicle is any single road transport vehicle (lorry), or combination of road vehicles, namely road train (lorry with trailer) or articulated vehicle (road tractor with semi-trailer), designed to carry goods
Cross-trade is international road transport between two different countries performed by a road motor vehicle registered in a third country.
National transport is Road transport between two places (a place of loading and a place of unloading) located in the same country by a vehicle registered in that country. 
International transport is Road transport between two places (a place of loading and a place of unloading) in two different countries and cabotage by road. It may involve transit through one or more additional country or countries.
Transit is any loaded or empty road motor vehicle, which enters and leaves a country at different points by whatever means of transport, provided the total journey within the country is by road and that there is no loading or unloading in the country.
Goods carried by road are any goods moved by goods vehicle
Place of loading/unloading of a goods road vehicle on another mode of transport

  • Place of loading (of the goods road transport vehicle on another mode of transport): The place of loading is the first place where the goods road motor vehicle was loaded on to another mode of transport (usually a ship or a rail wagon).
  • Place of unloading (of the goods road transport vehicle from another mode of transport): The place of unloading is the last place where the goods road motor vehicle was unloaded from another mode of transport (usually a ship or a rail wagon).

Each reporting country reports all activities of a road motor vehicle inside and outside its national territory. There is thus no risk of double counting at European level.

For all definitions please refer to the "Road freight transport methodology - Reference manual for the implementation of Regulation (EU) No 70/2012" Chapter 10: Definition of variables, classifications and codes" on Eurostat's website. 

National characteristics of surveys are presented in the publication "Methodologies used in road freight transport surveys in Member States, EFTA and 3 Candidate countries" on Eurostat's website. 

The reporting unit for road freight transport statistics is the goods road transport vehicle or the local unit (a site of a company, as identified in the national business register).  Please have a look at the methodology used in each reporting country during the different reporting years:

As the total number of statistical units (most commonly vehicles) in most reporting countries is very large, sample surveys are carried out to collect information. A representative selection is drawn from the population (see "Road freight transport methodology - Reference manual for the implementation of Regulation (EU) No 70/2012" Part A) in such a way that the desired attributes can be estimated, within the limits of a pre-defined precision, according to standard statistical theory.

"Methodologies used in road freight transport surveys in Member States, EFTA and 3 Candidate countries" includes summary tables with basic information on sampling, response rates, register quality and precision of results of the surveys in the reporting countries.

The data cover European Union, EEA and candidate countries. The time coverage follows the enlargement of the European Union.

Data collected under the Directives 78/546/EEC and 89/462/EEC cover mainly EU-14 countries. New Member States provided generally data starting from the date of their accession to the EU; therefore, historic time series are not complete for all countries.

The data based on Regulation (EU) No 70/2012 cover today all EU-MS (except Malta exempted), Norway, Liechtenstein (since 2005 and until 2013; from 2014, Liechtenstein is exempted from the reporting of road freight data), Switzerland (since 2008) and Croatia (since 2008) - Iceland is exempted.

The coverage is shown in the 'Data availability' tables, updated regularly on CIRCA.

The road data are collected on a quarterly basis and are reported to Eurostat five months after the end of the reference period.

Commission Regulation No 642/2004 on precision requirements requires that, even in the smallest reporting countries with less than 25 000 relevant vehicles, at least 7 of the 13 weeks of each quarter shall be covered by the survey.

Road freight data come from sample surveys. The overall sampling error of the estimates for the large reporting countries of the total and the national transport should be within 5% standard percentage error (SPE).

Regarding bias, underreporting is clearly an issue that has been identified in different benchmarking exercises.

 

Data are collected in tonnes, tonne-kilometres, vehicle-kilometres and in number of journeys (journey data) or in number of basic transport operations, BTO (goods related data).

The time unit is mostly one week (Germany, one of the biggest reporting countries, collects data during half a week, Finland collects data every 3 to 4 days), the time units covered in a year are mostly 52 weeks (see methodologies used in reporting countries); the submitted micro-data are extrapolated (grossed up) by Eurostat on the basis of the reported weighting factors to obtain quarterly data.

Annual data are summed up from the quarterly data.

The "three-layer structure" of data (vehicle data, journey data and goods data) allows calculating some vehicle data from the journey data and some journey data from goods related data. The data aggregated from different layers do not always match perfectly, due to different reporting practices.

The data published on basic transport operations (BTO) may not be reliable in all dissemination tables: User feedback suggests that, for multi-stop journeys representing less than 10% of all journeys, the number of basic transport operations is underestimated by a factor of 2-4.

The reported values are expressed in plain quantities, without the calculation of indices. Data are not seasonally adjusted.

Aggregates are calculated without Malta, which is exempted from reporting road freight statistics.

The compilation of European aggregates on the level of origins (places of loading) or destinations (places of unloading) are also produced and published in the tables.

Following a partial redesign of the French survey in 2020, the calculation of the weighting factors for the vehicles was impacted. This change in the weighting factors affects the final number of vehicles in the different categories by maximum permissible laden weight (MPLW) and load capacity (LC). Therefore, in the first quarter of 2020 there is a break in time series. The total is provided, while the breakdown by the different MPLW and LC categories is estimated. Revised data for 2020 to 2022 will be provided soon. This text is also available in the country and table specific notes loaded in CIRCABC.

Certain totals might be different when they are compared with the sum of their components (e.g. summing up the data by axle configuration will give a slightly different result than the total). This is due to the use of 'u' flag, which is applied in the detailed data, whereas in the totals the values marked with 'u' are included.

Data for road freight transport are micro-data obtained through questionnaires sent out by Member States to a sample of hauliers for vehicles registered in their country. These micro-data concern the vehicles themselves, their journeys and the goods that were transported.

Recently several reporting countries have started using electronic questionnaires, either Web based or applying Adobe Acrobat format.

This data collection through sample surveys (geographically and in time) is carried out by National Statistical Institutes or other Competent National Authorities (e.g. Ministries of Transport) in charge of data collection for road freight transport statistics.

The keepers of vehicle registers of the reporting countries frequently submit extractions to the statistical authorities. These extractions are used in sampling and in identifying the contact information of the owners of the vehicles. 

Data on vehicles (dataset A1) are partly extracted from the reporting countries' vehicle registers. Depending on the country, some variables are collected from the owners of the vehicles.

Data on journeys and goods (datasets A2 and A3) are most often based on on-board journals, filled in by the drivers during the survey period. Especially in larger commercial road freight companies, some journey and goods information can be extracted from the database of the company (consignment notes or waybills).

Type of goods and activity of the company are often collected in free text on questionnaires and the statistical authorities re-code the data according to the relevant classifications.

The coding of loading and unloading places is mostly reported as place name (locality) or postal code of the loading and unloading place. The statistical authorities then re-code the loading and unloading places to NUTS-3 regions in the EEA countries and Switzerland. Loading and unloading places outside this area are coded only with country codes.

The tables consist of annual and quarterly data.

Quarterly data are updated quarterly, but at irregular intervals within 2-3 months after the data delivery from the reporting countries to Eurostat. Eurostat receives the data generally 5 months after the end of the reference period. The exact date for updates depends on the availability of data.

Annual data are updated for the first time in June-July of the consequent year and thereafter, together with quarterly updates, if new or revised annual data are available.

Data are normally updated once per quarter.

Data are submitted to Eurostat within 5 months after the end of the reference period. Data are published within 2 months after arriving to Eurostat.

If new annual data (all four quarters of a calendar year) have become available, the annual datasets are also updated together with the quarterly datasets.

A similar survey methodology, based on Road freight transport methodology, is generally applied by all reporting countries. In general rule, the definitions are the same with those presented in the manual. For this reason, the geographical coherence of the EU road freight statistics is generally very good.

 However, there are some national characteristics of surveys that should be kept in mind when comparing the estimates:

  1. Weight. According to Regulation (EU) No 70/2012, gross weight (excluding packaging, pallets and containers) should be reported. For different reasons (for example, in order to maintain coherence with rail and inland waterways transport statistics) several reporting countries report gross-gross weight instead of gross weight. In practice, only the weight of journeys using containers and swap-bodies is significantly affected by the different reporting practices - in EU aggregates this means less than 1%, because the share of containers is generally less than 10%.
  2. Multi-stop journeys. There are two ways to report multi-stop journeys: reporting by consignment and reporting by consecutive stops ("vertical stages", see Road freight transport methodology, p, C-8). In the aggregation of micro-data by Eurostat, these two methods give different results, affecting the total weight of goods. The ways of reporting multi-stop journeys by the reporting countries are listed in Methodologies used in road freight transport surveys in Member States, EFTA and 3 Candidate countries.
  3. Classification of containers. Type of cargo is an optional variable, reported by most of the reporting countries. Swap-bodies are generally reported as "large freight containers" according to UN Recommendation 21. Some countries reported swap-bodies as "other freight containers" until 2007 (included) before the Road freight transport methodology (p.B-77) was clarified on this issue. Data on how different countries report swap-bodies can be found in country and table specific notes.

The major events affecting comparability over time are reported in country and table specific notes.

There is a break in series between 1998 and 1999, when Council Regulation (EC) No 1172/98 entered into force. Previously the reporting countries only submitted aggregated data to Eurostat.
