Abstract:

Instances of fog or fog enhanced with smoke (non-photochemical smog) routinely reduce driver visibility on roadways throughout Georgia. Georgia has the fifth highest reduced-visibility–associated crash frequency of any state. This report provides an overview of fog formation and types of fog, and a review of previous studies that have examined the effects of fog and reduced visibility on driver behavior and crash rates. The main purpose of this study is to create an initial fog climatology for the state of Georgia based on data previously collected from automated weather observing system/automated surface observing system (AWOS/ASOS) units to anticipate the frequency of fog and smoke occurrences across the state. The study recommends conducting a follow-on study to identify specific locations where additional safety treatments may be warranted as well as potential changes to design policy to address these issues during the design process
