The main goal of this deliverable is to present the "final formulation" of driver-vehicleenvironment model, as it will be implemented in the SP1 simulation tool. This deliverable is focused on the development of a "model" and associated "simulation" of a Joint Cognitive System (JCS), with the main objective of being a predictive tool, in order to study (all) possible Driver-Vehicle-Environment (DVE) interactions with a specific attention to design and safetyanalysis. In particular, in this Deliverable, the final formulation of the models that will beapplied to generate a simulation of the JCS is discussed in details. Moreover, the most relevant part of the document is dedicated to the Driver model. The selected paradigm for modelling Driver behaviour is the so-called "Information Processing System" (IPS), which has been applied in almost all technological fields to describe human interaction with control systems, at different levels of automation. It consists in four steps, in which cover cognitive and behavioural aspects: - Perception and interpretation of information from Vehicle and Environment; - Formulation of goals and intentions and selection of tasks to be carried out; - Performance of actions on the control panel and vehicle commands. The important characteristic of this approach is that it allows to consider behavioural as well as the cognitive aspects of human behaviour.
