2.2 Preliminary analysis of data sources and data to collect
2.2.1 Source screening
The analysis of existing studies, the review of retrievable statistics and the evaluation of possible data sources is a fundamental task prior to task 1 content and data analysis.
The main relevant sources are the studies “SEALS – Statistical coverage and economic analysis of the logistics sector in the EU” and “BE-LOGIC - Benchmark Logistics for Co-modality”, which were carried out for the EU Commission in the years 2008 (SEALS) and 2011 (BE-LOGIC).
Another category of valid sources are the national statistics institutes of the EU Member States and the Eurostat database.
As the collection also addresses data with additional information, complementary sources are evaluated. The following table gives a list of sources and works which have been evaluated with an assessment profile that shows what kind of research was conducted.
