Harmonisation and comparabilityharmonize or –nise (transitive verb) 1. bring into harmony 2. cause to agree 3.reconcilecompare (transitive verb) 1.notice or point out likenesses anddifferences of 2. liken 3. make comparative or superlative of (adjective or adverb) (Collins compact dictionary)

***Quality of statistical data: data should be relevant, accurate, timely, accessible, coherent and comparable:

- Length of comparable time-series- Number of comparable time-series- Rate of differences in concepts and measurement from European norms - Asymmetries for statistics mirror flows

(from “Doc. ESTAT/02/Quality/2005/9/Quality Indicators”)


Institutional context

Eurostat is part of the European Statistical System (ESS)– ESS = Eurostat + National Statistical Institutes of EU Member

States

Eurostat is a Directorate-General of the European Commission, similarly to– DG Energy and Transport,

– DG Competition,

– DG Environment etc.

Eurostat, as part of the European Commission (having the “right of initiative”) and together with the NSI’s, can make proposals of EU statistical legislation (regulations, directives, decisions)

Council Regulation n° 1172/98 on road freight statistics

Vehicle record

Journey record 2

Goods record 2

- vehicle age- activity (branch)- vehicle-kms- extrapolation factor

- vehicle characteristics- place of loading and unloading-transit countries- loading & unloading to another mode of transport

- weight of goods- distance- tonne-kms

- type of goods- dangerous goods- type of cargo- place of loading and unloading- tonnes- tonne-km- distance


Supportive rules and tools

Often Commission Regulations, but not always– Commodity classification: “Nomenclature uniforme de

marchandises pour les statistiques de transport” (NST): NST (1961), NST/R, NST 2007, …

– Geographic classification: “Nomenclature des unités territoriales pour statistiques” (NUTS): NUTS 1999, NUTS 2003, NUTS 2006,…

– Classification of Economic Activities: NACE rev.1.0, NACE rev.1.1, NACE rev.2.0, …

– Classification of type of cargo: United Nations Recommendation 21

Common classifications



Road freight transport methodology Volume 1Reference manual for the implementation of Council Regulation N° 1172/98 on statistics on the carriage of goods by road(in English, German and French)

Road freight transport methodology Volume 2Methodologies used in surveys of road freight transport in Member States and Candidate Countries(in English only)

Reference manuals



The two classifications that impose the biggest burden to national statistical authorities:– Type of goods (NST/R => NST 2007)– Loading and unloading places (NUTS-3 regions)

Respondents identify:– Type of goods by writing its name in questionnaire

• For international transport, customs document can be of use (single administrative document, Intrastat declaration)

• For dangerous goods, the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR) can be used to classify dangerous substances

– Loading and unloading places by writing place names or postal codes in questionnaires.

Data processing tools provided by Eurostat (1/3)



Eurostat provides reporting countries with tools that aim at facilitating and harmonising the handling of survey data:– Correspondence tables between NST 2007 on one hand

and Combined Nomenclature (CN), Statistical Classification of Products by Activity in the European Economic Community (CPA) and ADR classification on the other hand.

– List of localities and postal codes mapped to NUTS-3 areas: Index of Locations for Statistics in Europe (ILSE).



“Help desk” Eurostat receives and answers methodological

questions related to road freight surveys in the reporting countries



Management by standard error (1/2)

Legislation on which the road freight survey is based does not impose:– Sampling frame– Sample size– Stratification– Survey period

Instead, reporting countries should achieve an acceptable percentage standard error for main indicators in their sample surveys (Commission Regulation N° 642/2004) – means are to be decided by the reporting countries, not by Eurostat.


Management by standard error (2/2)

Annual- tonnes- tonne-km- vehicle-km

total and national

95%5%


Special issues of harmonisation

Coverage of surveys in reporting countries (Article 1(2) (b) of Council Regulation 1172/98):– “…shall not apply to…by means of…vehicles belonging to

central or local public administrations…”=> differences in how, for example, waste transport is treated between reporting countries

– At least vehicles with loading capacity above 3.5 t or maximum permissible laden weight above 6.0 t=> some countries but not all include light goods vehicles

Type of cargo – are “swap-bodies” classified as “large freight containers” or “other freight containers”?=>In future, all countries should classify containers purely on the basis of their size – this is not the case currently.

Extra-EU vehicles are not covered by these surveys; they still play different roles in different reporting countries.


Case: Fuel consumption of trucks (1/3)

Hypothesis: Collection of harmonised fuel consumption data of heavy goods vehicles in the sample surveys based on Regulation n°1172/98.

What would be required to introduce such new variable? Currently, only tonnes, tonne-km and vehicle-km data

are collected in the European survey. Some countries (CY, EL, HR, NL, RO, SI, SK and UK)

already have a question on fuel consumption in their survey questionnaires, but data are not sent to Eurostat.



The approach:– The need for data should be real, expressed (in written) by other

Eurostat units, DG Environment, DG Energy and Transport.– Eurostat would discuss the issue of data availability unofficially with some

reporting countries.– A proposal modifying the Annex A, with definitions and modification of

Commission Regulations n° 2163/2001 (data transmission), n°6/2003 (dissemination) and n°642/2004 (precision standard) would be drafted by Eurostat. Possibly a Task Force could be organised to better involve the reporting countries.

– Eurostat would bring the proposal to discussion in a road freight statistics working group (next mid-2009).

– On the basis of discussion, a decision might be proposed in a forthcoming CCST meeting.

– If approved by a large majority, the proposal would be brought to formal decisions making by the Statistical Programme Committee and the Commission.

– A legal act would be published in the Official Journal.

Conclusions

Eurostat, as part of the European Commission and the European Statistical System, has a heavy machinery for harmonising statistical data. This has both positive and negative aspects:

Pros (+)- Harmonised rules in all

reporting countries should contribute to harmonised data

- Possibility to support implementation by means of common tools

- Space for national variants

Cons (-)- Rigidity to adopt for new

requirements; almost everyone has to agree

- Difficulty to find ‘fair’ criteria for big and small countries (in sample surveys, small and big countries burden is almost equal)
