D5 Annex WP 3: DATABASE METHODOLOGY AND DATABASE USER MANUAL – FREIGHT TRANSPORT DEMAND For the rail and sea modes, the commodity classification can establish whether the goods are bulk or unitised. These headings can then be used to determine load factors in tonnes and FEUs respectively which will allow conversion to train numbers or ship numbers. In the case of the sea mode, there is a wide range of ship sizes, and in practice it may be easier to measure vessel flows (e.g. between ports) with reference to supply side data. For rail, provided that the mode share can be ascertained, conversions of tonnes or FEUs to train numbers could be usefully made. The road mode needs to be main focus of this procedure, as there is a wide variety of vehicle size possibilities, and there is no supplyside data (e.g. timetables) for road haulage services. The estimation needs to be informed by vehicle stock and survey data. There are differences in data availability by country, for instance in some national statistics up to 20 vehicle types are being distinguished where in other countries gaps exist. This data availability will be studied in the next phases in order to see whether improvements to the currently most used estimations are possible. In most cases the translation from tonnes to vehicles or vessels is done by one figure indicating the average number of tonnes per vehicle or vessel. Sometimes an estimate is made in this way of more than one type for instance van and truck. 4.8.4 Number of TEUs Determining the number of TEUs will be done by estimation. Different determining factors are present in this respect amongst which the volume of the commodities and the weight which has to be compared with the maximum volume and weight of a TEU and of course the efficiency of transport. Tables are existing of the volume per weight of the different commodities. Different container types have different maximum weights like for instance: Max weight: · 20 foot container (1 TEU) with a maximum weight of 20 tonne and · 40 foot container (2 TEU) with a maximum weight of 23 tonne Often the TEU is determined by applying the average of 9 or 10 tonne per TEU. It will be seen whether this method can be refined with available data. MDS Transmodal have developed conversion tables, similar to those used to estimate other cargo characteristics to relate tonnes of a product at the 5 Digit SITC level to the expected number of 20’ or 40’ units, using estimated stowage factors (tonnes per 20’ and tonnes per 40’). 28 Document2 27 May 2004
D5 Annex WP 3: DATABASE METHODOLOGY AND DATABASE USER MANUAL – FREIGHT TRANSPORT DEMAND 4.8.5 Transport performance information (tonnekm, vehicle km/vesselkm, TEU km) The estimation of transport performance information such as tonnekm, vehiclekm/vesselkm and TEUkm will be done in cooperation with the European transport network development since assignment on the network is required to determine the distance. Once the distance by mode has been determined between regions or by link in the transport network, transport performance information can be calculated by multiplying the transport volume information (in tonnes, in transport units and in TEUs) with the transport distance. This can be done for specific parts of the nework (for instance for the national territory of a country) or on a more aggregate level for total transport generated or attracted by a region or a country.
