6 DESCRIPTION OF THE WP 3 TESTING PHASE AND ITS RESULTS
6.1 General description of the testing phase
In the testing phase the proposed methods have been tested in order to find out whether they are
feasible and to determine whether and how the methods should be modified.
In WP 3 in total 6 different methods are tested in this phase. In the first method a country­tocountry
matrix in constructed. The second method determines where transhipment takes place
along the transport chain. To store this information in the database, a record structure with two
transhipment locations is introduced. Then in the third method the region­to­region flows are
estimated and included in the database. In the fourth step (pure) domestic transport is included.
After these four steps a complete region to region freight O/D transport chain matrix results. In
method 5 cargo characteristics and transport unit information is added to the database. Finally in
method 6 information about the transport performance (tonne­kilometres, number of vehicles,
vehicle­kilometres, number of TEUs, TEU­kilometres) is included.
6.2 Tested methodologies
In this paragraph the applied methods are described.
