Snow blowing and snow drifting are the major transportation issues in the mid-west regions of the US located in high altitude. The amount of snow that blows onto the road is sometimes 100 times bigger than the amount of snow that actually falls during a typical winter storm. The negative impacts are obstruction in the road user’s visibility and mobility, continuous snow plowing needs, travel delay, road accidents, excessive salt and chemical application, vehicular corrosion etc. Snow fences have been found to be effective in mitigating these negative impacts of blowing and drifting snow by working as a barrier against the wind-transported snow and depositing it on the designated areas on the side of the road. However, this effective snow control technology has been largely overlooked by industry because of not having adequate knowledge on the safety as well as cost effectiveness of the snow fences. In this study, the safety effectiveness of the snow fence has been identified by developing the Crash Modification Factor (CMF). The cost effectiveness of the snow fence was evaluated by identifying all the costs and benefits of installing a snow fence by assuming an imaginary snow fence along a snow vulnerable road segment in Hudson, IL. The CMF values shows that snow fence along the interstate in IL is capable of reducing snow blowing crashes as high as 37%. The evaluation of costs and benefits for two different types of snow fences shows that, for overall transportation industry the benefit to cost ratio is more than 1.
