Hot Shots for Cold Climes - Evaluating Treatment of the Hardest Icy Spots

Recent optimizations in deicer application by weather conditions have helped reduce costs and improve environmental impacts, and these optimizations have become the standard in winter roadway maintenance. When icy conditions develop on trouble spots, state patrol asks for more salt as vehicles are sliding sideways and crashes multiplying, and people may be getting hurt. In times like these, the consideration of environmental protection can be neglected, and much good work of deicer optimization can be negated. This study proposes to evaluate: the reduction in levels of service caused by these trouble spots; the frequency of occurrence; the winter maintenance response, particularly the additional deicer resources, targeted to the trouble spots; the calculated adjustment in environmental protection caused by this response.
