Costs and Benefits of Tools to Maintain Winter Roads

Some of the most useful data available to winter road maintenance managers and others charged with decision making are the costs, benefits, and effectiveness associated with winter maintenance of practices, equipment, and operations. However, significant effort may be required to track down this information, and access to published reports and papers is not guaranteed. This paper presents recent research results to assist practitioners in understanding the current state of the practice related to specific items. The information presented here focuses on the top 10 winter maintenance practices, equipment, and procedures as identified by practitioners, including anti-icing, deicing, front and underbody blades, automatic vehicle location and Global Positioning System technologies, pavement temperature sensors, road weather information system (RWIS), maintenance decision support system, carbide blades, air temperature sensors, and zero velocity spreaders. A review of the literature pertaining to these items indicated that, depending on the item of interest, significant data gaps might exist. This was less true for items such as RWIS and more true of items such as temperature sensors and material placement systems. Overall, quantified costs and benefits related to many items are still needed. In addition, further investigation is necessary to quantify the dollar values of costs and benefits associated with many items considered intangible at present. The determination of the values of such costs and benefits would assist in the conduct of cost–benefit studies and decision making.
