INFREDAT

Methodology for collecting intermodal freight transport data

In summary, the results of the INFREDAT project provide a comprehensive insight in the present data needs and data availability in the context of inter-modal freight transport, considering also possible future data sources and IT-based data collection methodologies. It was found out that the information currently available in the field of inter-modal flow data remains poor and fragmented. There are detailed but dispersed data about nodes and links, but only on a mode by mode basis. No data base exists at the European level that is based on a real inter-modal approach. The main elements of the 'data collection methodology' are the description of how acomplete data base structure has to be defined and a data model for the estimation and forecast of missing or future data need to be developed, and – in concrete – which data have to be collected, and how to fill the data base structure proposed. On the basis of a cost/benefit – cost/effectiveness analysis, the collection methods are ranked according to their cost/effectiveness ratio and recommendations for the sequence of implementation of different collection methods are given. Further relevant findings could be identified with the help of the pilot case studies and indiscussions with the members of the Advisory Committee.
