这篇文章描述了技术如何减轻抗击冰雪的工作。人们注意到，降低除冰除雪成本的最好方法是通过减少道路积雪和/或避免错误警报来最大限度地减少除冰除雪的需要。据介绍，积雪栅栏是保持公路畅通的有效手段。战略公路研究计划(SHRP)的研究表明，围栏必须至少有8英尺高，围栏底部与地面之间的间隙等于围栏高度的10%-15%，并且放置的距离必须至少是围栏高度的35倍。嵌入在道路上的传感器会告诉你道路的温度何时降至冰点以下，以及何时开始结冰或积雪。描述了它们在印第安纳波利斯的使用情况。描述了最近开发一种附着在传统犁刀片上的雪铲的研究。模拟显示，犁车的能源和燃料消耗减少了20%。还指出了一种粗粒化的路面顶层，它可以吸收水分并帮助它远离路面，也就是所谓的爆米花路面。
The article describes how technology eases the job of fighting ice and snow. It is noted that the best way to cut the cost of ice and snow removal is to minimize the need for it by reducing the buildup of snow on roads and/or avoid false alarms. It is described how snow fences are an effective means of keeping highways clear. Strategic Highway Research Program (SHRP) studies show that the fence must be at least 8 feet high, have a gap between the bottom of the fence and the ground equal to 10 - 15 % of the fence height, and be placed at a distance of at least 35 times the height of the fence. Sensors embedded in roads tell when the temperature of a road falls below freezing and when ice or snow begins to accumulate. Their use in Indianopolis is described. Recent research to develop a snow scoop that attaches to a conventional plow blade is described. Simulations show a 20% reduction in the energy and fuel used by a plow truck. A coarse grained top pavement layer that absorbs water and helps to keep it off the road, a 'popcorn,' pavement is also noted.
