How do snow fences affect traffic flow?

As a supplier of snow fences, I’ve witnessed firsthand the significant impact these structures can have on traffic flow. Snow fences are not just simple barriers; they are crucial tools in managing snow accumulation and ensuring safe and efficient transportation during the winter months. In this blog, I’ll delve into the science behind snow fences, their effects on traffic flow, and why they are a vital investment for any region prone to heavy snowfall. Snow Fence

The Science of Snow Fences

Snow fences work on a simple yet effective principle: they disrupt the wind flow, causing snow particles to settle out of the air and accumulate in a controlled manner. When the wind encounters a snow fence, it is forced to rise and slow down. This reduction in wind speed reduces the ability of the wind to carry snow particles, causing them to fall to the ground. The snow accumulates on the leeward (downwind) side of the fence, creating a snowbank.

The effectiveness of a snow fence depends on several factors, including its height, porosity, and spacing. Taller fences are generally more effective at trapping snow, as they can disrupt the wind flow at higher altitudes. However, the height of the fence must be balanced with its cost and the available space. Porosity refers to the percentage of open space in the fence. A fence with a higher porosity allows some wind to pass through, which can help to prevent the formation of a large snowdrift directly behind the fence. The spacing between snow fences is also important, as it determines the width of the snowbank that will form.

Effects of Snow Fences on Traffic Flow

Reducing Snowdrifts on Roads

One of the primary ways that snow fences affect traffic flow is by reducing the formation of snowdrifts on roads. Snowdrifts can completely block roads, making them impassable and causing significant delays. By trapping snow before it reaches the road, snow fences help to keep roads clear and open for traffic. This is especially important for highways, where snowdrifts can pose a serious safety hazard to motorists.

Improving Visibility

Snow fences can also improve visibility for drivers. When snow is blowing across the road, it can reduce visibility to near zero, making it difficult for drivers to see the road ahead. By creating a snowbank on the leeward side of the fence, snow fences help to block the wind and reduce the amount of blowing snow on the road. This improves visibility and makes it safer for drivers to travel.

Enhancing Road Safety

In addition to reducing snowdrifts and improving visibility, snow fences can also enhance road safety by preventing snow from accumulating on the shoulders of the road. When snow accumulates on the shoulders, it can create a soft and unstable surface, which can cause vehicles to lose traction and slide off the road. By keeping the shoulders clear of snow, snow fences help to provide a safer margin for drivers in case of an emergency.

Reducing Maintenance Costs

Snow fences can also help to reduce maintenance costs for road authorities. By preventing snow from accumulating on roads, snow fences reduce the need for snowplowing and salting. This can save time, money, and resources, as well as reduce the environmental impact of snow removal operations.

Case Studies

Interstate 80 in Wyoming

Interstate 80 in Wyoming is one of the busiest highways in the United States, and it is also one of the most prone to heavy snowfall. In the past, snowdrifts on the highway have caused numerous accidents and closures, resulting in significant economic losses. To address this problem, the Wyoming Department of Transportation installed snow fences along a section of the highway. The snow fences have been highly effective at reducing snowdrifts on the road, improving visibility, and enhancing road safety. As a result, the number of accidents and closures on this section of the highway has decreased significantly.

Trans-Canada Highway in Alberta

The Trans-Canada Highway in Alberta is another example of a highway that has benefited from the installation of snow fences. The highway passes through a region that is prone to heavy snowfall and strong winds, which can create dangerous driving conditions. To improve safety on the highway, the Alberta government installed snow fences along a section of the road. The snow fences have helped to reduce snowdrifts on the road, improve visibility, and enhance road safety. As a result, the number of accidents on this section of the highway has decreased, and traffic flow has improved.
