D5 Annex WP 3: DATABASE METHODOLOGY AND DATABASE USER MANUAL – FREIGHT TRANSPORT DEMAND Recoding of variables and modification of record structure After the selection between import and export registration has been made, the origin country and the destination country variables are recoded into the ETIS reference database country classification. Besides, the record structure is modified: · Origin country (ETIS country classification) · Destination country (ETIS country classification) · NSTR 2 digit commodity classification · Value of the goods (in Euro) · Volume of the goods (in tonnes) · Indicator absolute difference between import and export registration · Indicator relative difference between import and export registration · Indicator for intraEU or extraEU trade Adding information about the mode of transport The used Comext database has the advantage that it includes information about the traded goods on a very detailed level which makes it possible to add information about the cargo characteristics as described above. A disadvantage of this database is that it includes no information about the mode of transport. Besides the Comext database used up to now, there is another Comext database called ‘Comext trade by mode’ that includes less detailed commodity information (on NSTR 3 digit level), but it includes information about the mode of transport. The definition of the transport mode included in the Comext trade by mode database is as follows: · For intraEU trade the mode is defined as the active means of transport with which goods are presumed to enter/leave the statistical territory of the Member State for import/export; · For extraEU trade the mode is defined as the active means of transport with which goods are presumed to enter/leave the statistical territory of the European Community for import/export. For extraEU trade there is one registration with one modalsplit that gives the mode of transport for the goods entering or leaving the European Community. For intraEU trade the situation is more complex, there are two registrations with two modalsplits that give the mode of transport on the territory of the exporting Member State and the mode of transport on the territory of the importing Member State. In the same way as for the different registrations of the total trade volumes, the different registrations of the modalsplit have to be converted into one registration of the modal split. The following method is applied: 46 Document2 27 May 2004
D5 Annex WP 3: DATABASE METHODOLOGY AND DATABASE USER MANUAL – FREIGHT TRANSPORT DEMAND 1. In the Comext trade by mode database the distinguished modes are recoded into the transport modes used in ETIS for freight transport (road, rail, inland waterways, maritime, rest); 2. From the Comext trade by mode database for each country to country by commodity classification by cargo characteristics combination the modalsplit is determined once in the export registration and once in the import registration, the trade volumes are scaled to the volumes as selected between the import and the export registration; 3. A rule is applied to determine the origin mode – destination mode combinations: a. For each transport mode, the minimum volume is determined in the import and the export registration, for this trade volume the origin mode is equal to the destination mode. For instance if the export registration gives 1000 tonnes trade by road and the import registration gives 1500 tonnes trade by road, then the trade volume of the combination origin mode road – destination mode road becomes 1000 tonnes. b. For the trade volumes left after step a the origin mode and the destination mode cannot be the same. An order is determined in the modes of transport: maritime transport has the highest order, followed by inland waterways transport, rail transport, road transport and finally the rest category has the lowest order. The trade volume of the origin mode with the highest order is matched first with the destination mode with the highest order, then with the destination mode with the following order, etc. until the total trade volume of the origin mode is matched with the destination mode. Then for the origin mode with the next order the same procedure is applied etc. until all origin modes have been matched with destination modes. The example in the table below illustrates the effect of this procedure. Table 6.3 Modes in export registration Example of procedure to match origin mode and destination mode Modes in import registration Road 2000 tonnes Road 1700 tonnes Rail 500 tonnes Rail 600 tonnes Inland waterways 500 tonnes Inland waterways 300 tonnes Maritime 1500 tonnes Maritime 1900 tonnes Rest 200 tonnes Rest 200 tonnes The method results in the following origin mode – destination mode combinations Origin mode Destination mode Transport volume Remark Road Road 1700 tonnes Direct transport Rail Rail 500 tonnes Direct transport Inland waterways Inland waterways 300 tonnes Direct transport Maritime Maritime 1500 tonnes Direct transport Rest Rest 200 tonnes Direct transport Inland waterways Maritime 200 tonnes Indication transhipment Road Maritime 200 tonnes Indication transhipment Road Rail 100 tonnes Indication transhipment In case the origin mode is different than the destination mode, this is interpretated as an indication that transhipment might have taken place along the route. In the next methods this information is used to include transhipment information to the database. Document2 27 May 2004 47
