STRADA

The analysis of data on transport developments is one major objective in the transport research focus of the German Aerospace Center (DLR). Following this objective, DLR’s Institute for Transport Research offers with the Clearing House of Transport and Mobility a unique collection of publicly funded travel and mobility surveys for Germany and is official provider for German household surveys and statistics. Additionally, information about similar statistical data sets and data portals in Europe is made available. The Institute of Air Transport and Airport Research as second DLR institute in the mentioned field provides with the “MONITOR” portal detailed information and statistics concerning air transport developments. With a set of indicators the institute performs furthermore analyses of the global long-term air transport development regarding air traffic and financial performance besides sustainability issues. As both institutes use the Dublin Core Standard for the description of the data sources in use, in 2011 the idea came up to realise a common (meta-)data repository for interested users which have the need to combine and investigate different transport statistics. Accordingly, the project “STRADA@DLR” (Search TRAnsport DAta @ DLR) was launched in cooperation with DLR’s Facility on Simulations and Software Technology to create an external search and analysis system allowing directed access to the mentioned data repositories.
