Abstract
Reduced visibility is a common casual factor in many traffic accidents. This paper describes a forward looking vision system which simultaneously tracks the lane and estimates visibility. The system estimates the visibility by measuring the attenuation of contrast between consistent road features at various distances ahead of the vehicle. Results of experiments on simulated images, as well as live vehicle tests are presented
