In traffic research, planning, and policy-making, there is a tremendous need for detailed information about traffic incidents and mobility behaviour. Consequently, there is an equally large and diverse range of statistics, empirical studies, and mobility research. Many relevant sources of data are known to only a small group of well-informed users or the usefulness of such data is limited by a lack of methodical supplementary information. The "Traffic Clearinghouse" at the DLR Institute of Transport Research serves as a centralized point of contact that closes this gap. The clearinghouse is oriented towards scientists and institutions that collect their own data as well as those who wish to take advantage of these research results. These include not just scientific institutions, but traffic planners and policymakers as well.
The data offering provides access to a large number of data sets. These include detailed meta data as well as references to potential uses and sources. While this meta-information is freely accessible, the owner of each data set must approve access to the data itself.
How do you access data?
Data may be obtained by placing an advance order with the clearinghouse. Following agreement with the owner of the data, the released data is usually provided to the customer in the form of a CD-ROM sent via regular mail.
