Snow accumulation causes major safety concerns in the transportation industry such as from dangerous shedding of wet snow from bridge cables, and from blockage of sensors, camera lenses, LIDARs, and RADARs in semi or full autonomous vehicles (AVs). Snow accumulation can also reduce power generation efficiency in solar panels and wind turbines. 

In this talk, various active, passive, and administrative techniques are discussed to mitigate these snow accumulation issues. First, a numerical model is developed utilizing weather data to predict the shape and thickness of snow accumulation on bridge cables and their shedding behavior. This model is coupled with an experimental study and a novel snow/ice detection sensor to assist bridge operators in optimally utilizing their active systems for mitigation of snow issues. Next, two different navigators are designed to actively prevent snow accumulation on AV visual sensors via airflow across the lens surface, and I will also present results of a passive method that facilitates snow removal from solar panels. Finally, I will discuss how a combination of passive, active, and administrative strategies provide foreseeable means to address such snow accumulation issues.
