3.1. Data description | |||
Road freight data collection consists of three datasets with quarterly periodicity:
|
|||
3.2. Classification system | |||
Statistics on carriage of goods by road apply the following statistical classifications:
The optional variable type of cargo follows the Classification of Cargo Types of UNECE (United Nations, Economic Commission for Europe - codes for types of cargo, packages and packaging materials, Recommendation 21 adopted by the Working Party on Facilitation of International Trade Procedures, Geneva, March 1986). |
|||
3.3. Coverage - sector | |||
Statistics produced on the basis of Regulation (EU) No 70/2012 . Operations by small goods vehicles (vehicles with carrying capacity less than 3.5 tonnes) and extra-EEA vehicles are not covered in these statistics. Data are based on sample survey. |
|||
3.4. Statistical concepts and definitions | |||
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.
|
|||
3.5. Statistical unit | |||
The reporting unit for road freight transport statistics is the goods road transport vehicle. |
|||
3.6. Statistical population | |||
Data on freight traffic are collected from legal entities and natural persons who are owners or holders of lorries and road tractors that have gone through vehicle inspection at the moment of the survey and may be legally used. The survey does not include special vehicles – fire-fighter motor transport, motor cranes, platform lorries, road repair transport etc. – as well as lorries that are more than 25 years old and/or have a carrying capacity of less than 3.5 t; starting with 2017, special concrete mixers are included in the survey from the list of special lorries. |
|||
3.7. Reference area | |||
The data provided are goods vehicles registered in Latvia. |
|||
3.8. Coverage - Time | |||
The first reference year of reporting the regular road freight data to Eurostat was 2002. |
|||
3.9. Base period | |||
Not applicable. |
|
|||
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 one week, 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 road data are collected on a quarterly basis and are reported to Eurostat five months after the end of the reference period. |
|
|||
6.1. Institutional Mandate - legal acts and other agreements | |||
National level: Statistics Law. Council Regulation No 741 "Official Statistics Programme for 2023–2025 (in Latvian only) Council Regulation No 741 “Official Statistics Programme for 2023-2025”. European level: REGULATION (EU) N° 70/2012 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 18 January 2012 on statistical returns in respect of carriage of goods by road (recast). |
|||
6.2. Institutional Mandate - data sharing | |||
National level : Annually semi-aggregated data, which are received from Eurostat, are used for internal calculations only. From Eurostat : Eurostat submits annually semi-aggregated data (data exchange tables, see Commission Regulation (EU) No 202/2010 amending the Commission Regulation (EC) 6/2003) back to the reporting countries so that they can compile the total road freight transport on their national territories, including the operations by national hauliers and also those of all other reporting countries. These data exchange tables include more detailed breakdowns than the publicly available tables. They also include, for each value, the information on the number of observations that the estimates are based on. In this way, the reporting countries can estimate the reliability of results that they aggregate from the data exchange tables. |

10.7. Quality management - documentation | |||
Not applicable. |
|
|||
11.1. Quality assurance | |||
Road freight transport statistics are compiled by the competent national statistics authority. Data are collected and compiled in line with Regulation 70/2012, Regulation 1304/2007, Regulation 642/2004 and with the Code of Practice applicable to all processes for collecting and compiling European statistics. |
|||
11.2. Quality management - assessment | |||
The three main tools for the assessment of the quality of the aggregated road freight data are:
Data quality can be assessed as high. There is a set of validation rules and quality checks put in place, which detect various types of issues. In case of any issues detected, the data providers are contacted to provide explanations or/and revise the data accordingly. Quarterly, Eurostat provides a data quality report with a summary of the main findings affecting quality as well as showing the solution adopted and the materiality of the existing differences. |
|
|||
12.1. Relevance - User Needs | |||
International data users: Eurostat; United Nation; International Transport Forum. National data users: Ministry of Transport; Bank of Latvia; Public administration; Students; Mass media. |
|||
12.2. Relevance - User Satisfaction | |||
Not applicable. |
|||
12.3. Completeness | |||
As road freight statistics are based on sample surveys, the completeness of the data decreases as the detail of breakdowns increases. Therefore it is impossible to publish more detailed quarterly information. Quarterly is published main data (tonnes and tkm by type of transport) only. Detailed information (by type of goods, dangerous goods, by loading/unloading country, national transport by NUTS 3 level) is published on yearly bases only. |
|
||||||||||||
13.1. Accuracy - overall | ||||||||||||
Road freight data come from sample survey. According to Regulation 642/2004 Article 2 the overall sampling error of the estimates of the total and the national transport should be within 7% standard percentage error (SPE). Regarding bias, underreporting is clearly an issue that has been identified in different benchmarking exercises. |

18.3. Data collection | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Sampling methodology Statistical unit: Tractive vehicle. Types of units excluded: Special purpose vehicles such as truck cranes, fire-fighters vehicles, platform lorries, road maintenance vehicles, border guards’ vehicles and other special purpose vehicles. Vehicles older than 25 years. Vehicles with load capacity less than 3.5 tonnes. Starting with 2017, special concrete mixers are included in the survey in the list of special lorries. Time unit: 1 week. Time units of 2023 included in the survey: All (52 weeks), 13 weeks each quarter. Stratification: The sample for one month (5 weeks within the first month of each quarter and 4 weeks within the second and third month of each quarter) is obtained using a single stage stratified systematic sampling. The vehicles selected in sample for one month will be not sampled for six, nine or twelve sequence months, in order to reduce the workload for respondents. For the estimation of averages, totals, ratios and percentages the so-called Horvitz-Thompson estimator is used. It means that the probability for each vehicle to be included into the sample must be calculated. For every survey month the inclusion probability of a vehicle in the sample is calculated as a ratio between the number of vehicles that were included in the sample and did respond and the total number of vehicles in the stratum, i.e., the number of vehicles that had valid technical examination certificates in the survey month. This means that within each stratum the responding vehicles represent the non-responding ones of the same stratum, too. The estimates of totals and means are obtained first for each survey month and each stratum separately. The estimates of population totals and population means (or domain totals and domain means) are obtained by summing up or calculating the weighted sum over all strata and over all survey months of the corresponding strata estimates.
(1) European Agreement concerning the International Carriage of Dangerous Goods by Road. Recording of weight of goods: Gross weight of goods is collected, i.e. containers, swap bodies and pallets are excluded. Estimation of maximum permissible laden weight: Maximum permissible laden weight is estimated by adding load capacity and basic weight. Calculation of weighting factors: M Weighting factor = -------------------- S + S’ M = mean of population between the beginning and the end of the reference month. S = number of questionnaires used in analysis (in a stratum, during the reference period). S’ = number of vehicles for which no activity was recorded, but vehicles could be considered as active (holiday, no work, etc.). Recording journey data sent to Eurostat The questionnaire has 2 parts: one part for journeys with 1 to 4 stops and other for journeys with 5 and more stops. Single journey is journey when goods are loaded and then unloaded. Multi stop journey is journey, when goods are loaded then have some stops to load/unload goods and at the end all goods are unloaded. Each stop is recorded separately. If journey has 5 or more stops or collection/delivery journeys they are recorded as one. Such journeys have 5 types:
Depending on the number of stops, the type of journey is determined and tonnes and tkm are calculated based on the type of journey, respectively. Optional variables covered:
Additional variables collected compared to the legal requirements: Not applicable. A1. Vehicle-related variables:
A2. Journey-related variables:
A3. Goods-related variables: type of freight (Cargo types) as defined in the Regulation (YES). |

18.4. Data validation | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
National level : There are warning questions and error validations presented in a form of screen messages during the data entry. All errors should be corrected during the data entry. The Eurostat validation rules also are included in the data validation process. From Eurostat : Since 1999, micro-data from the reporting countries have to be submitted according to Commission Regulation 2163/2001. The data are then checked and validated by EUROSTAT (verification of many different codes used (NUTS 3, numeric or alphabetic variables) correctness of linked questionnaires in the different dataset, etc…). Detected errors are then reported back to the data sender with the request for correction, this is an iterative process until at least 99.5% of all data records are validated and loaded in the database. |
