5 TRANSPORT CHAIN FREIGHT O/D MATRIX – DATA NEEDS, DATA
COLLECTION AND REMAINING DATA GAPS
5.1 Introduction
In this chapter first the data needs for building a complete transport chain freight O/D matrix are
described for an ideal situation (where all required data is available). Next, an overview of the
data collection is given. Finally, data that is needed but that cannot be collected within the
project is described, this is called the remaining data gaps.
5.2 Data needs
The exact structure of the data construction methods that are applied is dependent on the input
to be found. In this section an overview is given of data needed in the database construction
process in an ideal situation where all required data is available and all available data can be
processed within certain limitations.
In general different types of data need to be collected to be able to construct the freight transport
database:
· Trade data (movement of goods)
· Transport data (movement of transport units)
· Maritime transhipment data
· Inland transhipment data
· Container data
· Vehicle/vessel movement data
From the other datasets developed within ETIS the following is required:
· Socio­economic data
· Network data
· Transport sector data
Each of the data types will be discussed.
5.2.1 Trade data
Since trade is the origin of all transport movements this data is the basis of the top down
approach to be applied. A consistent source for all countries is needed. This source preferably
should contain information about:
· Origin (region, country)
