Information to be provided to Eurostat
1. Member States shall provide Eurostat with information each quarter to permit the calculation of sample size, response rates and register quality rates. Where the primary sample unit is the goods road motor vehicle, the information shall be provided in the format of Table B1 in the Annex to this Regulation. Where the primary sample unit is not the goods road motor vehicle, the information shall be provided in the format of Table B2 in the Annex to this Regulation. The table shall be provided within the same timescale as for the transmission of the data set out in Article 5(3) of Regulation (EC) No 1172/98.
For the purposes of this Article, the following definitions shall apply:
(a) "response rate" means a value, of which the denominator is the number of sample units to which questionnaires were despatched to the selected operators, and of which the numerator is the number of sample units to which questionnaires were despatched, minus the aggregate of the number of units refusing to participate and the number of units for which no information of any kind was received;
(b) "register quality rate" means a value, of which the denominator is the number of sample units to which questionnaires were despatched, minus the aggregate of the number of units refusing to participate and the number of units for which no information of any kind was received, and of which the numerator is the number of sample units where vehicles were working actively during the survey period, plus the number of units where vehicles were not working during the survey period but could be considered to be part of the active stock of vehicles.
2. If the percentage standard errors of the data provided by a Member State pursuant to Regulation (EC) No 1172/98 have been calculated for a number of years and Eurostat has noted that these standard errors are within the limits laid down in Article 2 of this Regulation, Eurostat may release that Member State from the obligation to provide Table B1 or Table B2 on a quarterly basis.
3. Where paragraph 2 applies, the Member State may provide Eurostat with information for each year to permit the calculation of response rate and register quality rate. The information may be provided in the format of Tables B3 or B4 (as appropriate) in the Annex to this Regulation. The table shall be submitted within five months of the end of the last quarterly period of observation of the relevant year. In addition within the same timescale, the Member State shall provide Eurostat with the calculated figures of percentage standard error (95 % confidence) of the estimates for tonnes transported, tonne-kilometres performed and total kilometres travelled loaded for total goods road transport, for national goods road transport and for total international goods road transport.
