In order to be able to understand and predict the behavioural effects in a changing traffic and transport system a systems approach is the best way to model human adaptive behaviour. Behaviour can be described at various levels: strategic, tactic and operational. The process to be modeled can be described in terms of goals, tasks, functions, actions and properties of vehicle, road and environment. Since the description of the system is hierarchical, a top-down normative approach wil be used. The following aspects have to be taken care of: vehicle dynamics, modeled in terms of non-linear differential equations, goals and task definitions, visual perception, information processing, division of attention, processing, division of attention, decision-making, steering, accomodating rules, learning, workload, and the incorporation of secundary tasks and their interference.
