Online-Catalogue
In our online catalogue you can search and find subject-specific literature, research data and further information for your scientific work. At the present time our catalogue contains over 4,500,000 data sets relevent to transport and mobility research and it is constantly being expanded. So you can find what you are searching.
search terms and phrases
Search terms consist of one or more words. If the words are not combined with a Boolean operator (see below), search terms will be linked by AND by default.
Example: traffic flow
This search query will show all data sets containing the terms "traffic" and "flow" (also synonyms).
Search phrases are enclosed with quotation marks.
Example: "traffic flow"
This search query will only show data sets containing the precise words in that order "traffic flow".
Boolean operators and Brackets
You can use the Boolean operators AND, OR and NOT (in capital letters) in your search query. If you want to use several operators, you will have to use brackets to logically seperate each search term.
Example: (mobility OR transport) AND research AND NOT e-mobility
This search query will show all data sets containing either "mobility" or "transport" and always containing "research" but never containing "e-mobility".
Wildcard characters and Placeholders
You can modify your search terms with wildcard characters such as asterisks (*) and questionmarks (?). A questionmark is used as a placeholder for one letter. An asterisks can be interpreted as a number of literal characters or an empty string. Wildcard characters can be combined and used several times in a search term. However, they cannot be used in search phrases.
Example: c?t
This search query will show data sets containing words such as "cut" or "cat" and more.
Example: laser*
This search query will show data sets containing words starting with "laser" or including "laser".
