The analysis of driving behaviour : manoeuvring as a decision process.

Driving behaviour can be analysed at different levels: - choice of destination and means of transportation; - route choice; - manoeuvre selection, for instance overtaking or car following; and - vehicle operation. As to manoeuvre selection, a number of aspects can be mentioned such as: the available and minimum space and time needed for carrying out the manoeuvre - depending on traffic, road and vehicle characteristics - and psychological aspects such as the driver's response, perception, information and decision capacities. A simplified scheme of the decisions to be taken on approaching a vehicle ahead is given in Figure 1
