Dept. of TransportationUS Transportation CollectionThe goal of this research project was to develop a method to measure the performance of winter maintenance operations. First, the impacts of winter weather on safety (crash rates) and mobility (average vehicle speeds) were measured. Second, a storm severity index was developed. Third, for a given road class and a given storm severity an expected speed reduction was developed, which can serve as a performance target for winter maintenance operations.75
