This report provides the material for the production of a database underlying the definition of a so-called `design road user'. Is does so by providing an inventory of (1) dose-effect relations between road user characteristics and behavioural/safety parameter, and (2) distributions of relevant parameters in the (driving) population. Relevant characteristics have been divided into: (1) background characteristics (demographic, temporary, or permanent); (2) characteristics of human information processing functions (attention, perception, cognition, and motor reactions); and (3) characteristics of behaviour displayed on the road. On the basis of the literature it is determined for which of these characteristics these exists sufficient evidence to have it included in the database. (A)
