Résumé / Abstract
The transportation research group of the university of Southampton has equipped a vehicle with different sensors in order to obtain data on driver behaviour ; it has been used for the EC funded DIATS project, which aims to evaluate scenarios for the intelligent road, and which requires as its starting point a good knowledge of baseline behaviours in different European countries. In this paper we present some results addressing behaviour in car-following conditions: every car-following sequence is separated in different phases, linked to the sign of the relative speed, or to the sense of evolution of this relative speed; the analysis of the steady phases results in some identification of the noise in driving i.e. what is happening from a kinematic viewpoint when no decision or particular action is required from the driver. This noise, with the corresponding environment effects, might be important in systems as adaptive cruise control. The environment effects of another system addressed in the DIATS project - the variable speed limits can be linked to the existence of the other (transient) phases.
