Data on Road freight transport are available to all users of the NSI website under the heading Domain statistics - Transport and Communications - Other annual data - Transport: http://www.nsi.bg/en/node/7167

The access to micro-data for research purposes is granted according to Commission Regulation (EC) No 831/2002 on access to confidential data for scientific purposes (addition of the 4 surveys:

European Health Interview Survey (EHIS), Community Statistics on Information Society (CSIS) - module 2: Households and individuals, Household Budget Survey (HBS), Carriage of Goods by Road (CGR).

Data on road freight transport from all reporting countries are published on the internet site of Eurostat.

The survey is carried out according the international requirements.

Main users are state institutions, different organizations and specialized in the sector enterprises.

Not applicable.

From the survey are excluded vehicles with gross weight under 6 tonnes, military vehicles, vehicles of Ministry of Interior and other public administration, agricultural tractors and other motor vehicles non designed to carry goods, vehicles with weight and dimensions exceeding the normal permitted limits of the country.

Road freight data come from sample survey. The sample error should by up to 5%.

At the end of each reporting year the sample error in % is calculated. An error is calculated for each stratum separately in order to obtain the total error of the sample. This is done in respect of the tonnes and tonne-kilometres.

Underreporting can be considered as a prevalent bias of the road freight statistics. Having in mind that respondents ease their burden by omitting journeys, the underreporting is in principle an imminent systematic error.

The necessary actions are taken in order to reduce this error to minimum and to ensure better quality and completeness of the received data.

Quarterly data are transmitted to Eurostat 5 months after the reference period.

All the data are transmitted according to the set deadline in the Regulations.

Road freight statistics is different from those of other transport modes and the most important characteristic is that the values are estimates based on sample surveys and that each reporting country reports on its haulier? operations all over the world, not just on national territory.

Cost and Burden for the survey are defined according the National Statistical Program for each reference year.

Countries can update incomplete or revised datasets referring to previous quarters at the same time when they submit new quarterly datasets. Data are revised on the basis of detected errors.

See 19.1.

The information is obtained weekly from all freight vehicles with weight over 6 tonnes included in the sample for the reference period.
