Samenvatting
This paper describes an effective possibility to describe human behavioursystematically with appropriate accuracy by using Numerically Described Multidimensional Probability Distributions (NDMPD). A tool to handle the large amount of numerical data is provided. NDMPD may be used as a part of asystem-wide systematical and modular risk analysis of complex technical systems with a relevant influence on human behaviour (e.g. road traffic). Aframework for such analysis is presented. The modularity allows for the enhancement of the analysis on a module by module basis and supports the cooperation of different researcher's groups even from different disciplines. One of the aims of this paper is to establish such cooperation. (Author/publisher).
