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 in compliance with the Regulation No. 70/2012 covers the following road freight transport operations on the CZ territory as well as abroad by goods vehicles registered in the Czech Republic with a load capacity equal or more than 2 tons: - Commercial road freight transport referred to as "Hire or reward" road freight transport - Road freight transpor by vehicles owned by companies classified in other classes than professional road freight transport. This kind of transport is identified as "Own account" transport. Transport by smaller vehicles (less than 2 tons of load capacity) is not covered by this statistics. Road freight statistics carried out according to the mentioned EU legal act is a 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 a goods road transport vehicle. |
|||
3.6. Statistical population | |||
As the total number of statistical units (most commonly vehicles) is very large, sample surveys are carried out to collect information. |
|||
3.7. Reference area | |||
The data provided are goods vehicles registered in the Czech Republic uniquely. |
|||
3.8. Coverage - Time | |||
The first reference year of reporting data on road freight transport was 2004 |
|||
3.9. Base period | |||
Not applicable. |
|
|||
Data are collected in tonnes, tonne-kilometres, vehicle-kilometres and in number of journeys (journey 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: Act No. 89/1995 Coll., on the State Statistical Service, as amended. According to the above mentioned legal act, every year the Czech Statistical Office in cooperation the Ministries prepares a Program for statistical data collection in order to collect data and compile statistics for national as well as international purposes. After this program is approved by the government, all the respondents concerned are obliged to report to the Czech Statisticl Office or to the relevant Ministry
European level: |
|||
6.2. Institutional Mandate - data sharing | |||
National level : Detailed data are shared only upon request with state administration and only for statistical purposes. In some cases data are made available to researchers. Provisions of such data are subjected to signature of an agreement of use. 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. |

|
|||
7.2. Confidentiality - data treatment | |||
According to the Czech legal base, data on an individual enterprise (or reporting unit) or data from which this information can be easily obtained cannot be published or otherwise disseminated. In practice it means that only aggregated data based on the data from at least 3 reporting units can be published. In road freight transport a problem arises if e.g. for some goods commodity data are aggregated on a low level, then these data could be considered as confidential. |

18.1. Source data | |||
Sampling register used for the survey Name of register: Central Register of Vehicles Name of organisation who maintains the register: Ministry of Transport Frequency of update: Continuously Frequency of access to draw the samples: Once a quarter Arrangements for accessing the register: Sample of road vehicles is being selected by the administrator of the Central Register of Vehicles following agreed criteria (according to territorial units and weight categories). Information obtained from the register: List of vehicles including assigned license plate, holders of vehicle company, territorial unit (districts), type of body of goods road vehicle, weight category, vehicle type, year of first registration, fuel used, load capacity, permissible weight and number of axles. Used in stratification: Load capacity, vehicle type and territorial unit. Procedure for reminders: The questionnaire for a given period surveyed is sent one week in advance. The deadline for response is 12 days following the end of the period surveyed. The first reminder is sent 14 days following termination of the mentioned period. If no response is received within next 14 days, the second reminder is sent to the vehicles holder. If the Ministry of Transport is informed about the recent change of the ownership of a vehicle (not recorded in the register yet) or about leasing of a vehicle, then, if possible a questionnaire is sent once more to the real operator of the vehicle. The response rate is considered quite adequate, it varies around 91%. |
|||
18.2. Frequency of data collection | |||
Data are collected weekly. |
|||
18.3. Data collection | |||
Sampling methodology Statistical unit: Tractive vehicle Types of units excluded: Vehicles with a load capacity less than 2 tonnes and vehicles with oversized load, agriculture vehicles, military vehicles and public administration vehicles. Time unit: 1 week Time units of quarter 1 of 2022 included in the survey: All (13 weeks) Stratification: The sample is stratified according to 4 weight categories and 8 territorial units. Weight categories: 1. 2 - 6 tonnes 2. 6 - 10 tonnes 3. More than 10 tonnes 4. Tractors Territorial units: 1. Praha 2. Střední Čechy 3. Jihozápad 4. Severozápad 5. Severovýchod 6. Jihovýchod 7. Střední Morava 8. Moravskoslezsko The stratum code consists of 2 numbers. The first is the code of the weight category and the second is the code of the territorial unit (e.g. 11, 12, ..., 18, 21, 22, ..., 28, ..., 41, ..., 48). Recording of weight of goods: Gross weight of goods is collected. Large freight containers and swap bodies are excluded from the weight of goods. The pallets are included in the weight of goods. Recording of journey data sent to Eurostat: Single stop: Respondents can record only one type of goods, i.e. goods of largest weight. Collection/delivery: The first place of loading of the goods and the furthermost place of unloading is being used. Other variables: Most frequently used type and axle configuration of trailers or semi-trailers during a surveyed week is used for coding. Calculation of weighting factors: N = number of vehicles in the register (in a stratum) S = number of questionnaires used in analysis (in A1 dataset) S’= number of vehicles for which no activity was recorded, but vehicles could be considered as active (holiday, no work, etc.) Optional variables covered: A1. Vehicle-related variables:
A2. Journey-related variables:
A3. Goods-related variables:
Additional variables collected compared to the legal requirements: Environmental impact-related variables: none
|
|||
18.4. Data validation | |||
National level : Logical calculation is carried out when uploading received data into the database. Microdata are aggregated and compared to previous quarters and time series are checked. 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. |
|||
18.5. Data compilation | |||
After various plausibility checks, the data received from a vehicle owner are compliled into quarterly data following the structure of the data sets in the Regulation (EC) 70/2012. Data are calculated on country level and on NUTS3 level. |
|||
18.6. Adjustment | |||
Road freight data are not seasonally adjusted. |
