1997, WERD undertook a project called RADEF (Road Administration Data
Exchange Format) to enable the exchange of highway information among
both road administrations and commercial organisations by developing
common standards and tools and promoting their use.
A key part of this project was the creation of a common Data Dictionary, providing agreed terms, definitions, categorisations and relationships for highway data, such as traffic, accidents, and road network and condition statistics. Common location referencing is a particularly important component.
The European Road Data Dictionary can be downloaded as a .pdf file. Please right click on the hyperlink and choose ‘save target as’, then select from the menu a location to save the file to. To download Adobe Acrobat Reader please click here...
