Caractérisation, modélisation et simulation des effets visuels du brouillard pour l'usager de la route

TL;DRAbstract

Dense fog is a major road safety issue. Improving road users' safety involves prevention, forecast, detection, as well as signalling, lighting and driver assistance. However, in order to design suitable road or vehicle solutions compensating for the loss of visual information, accurate understanding of how fog reduces visibility is necessary. Evaluating such solutions in terms of driving behaviour requires the use of simulation, because tests in real foggy traffic are unpractical. The goal of this work is to describe how fog impairs the driver's visual environment, in order to model and simulate the visual effects of fog. <br />In the first bibliographic part, we notice the gap between the complex and varied microphysical and optical aspects of fog on the one hand, and the oversimplified notion of "visibility range" commonly used to describe its perceptive effects on the other hand. We show that frequency analysis is necessary to characterize the scattering-induced perturbations to the
