Impact Factor for Winter Severity Indices

Winter severity indices have been utilized for several years by a variety of groups and organizations who deal with winter weather. These indices take into account weather attributes such as total snow and/or ice accumulation, snow and ice rates, persistence of cold weather and other variables, and quantify those attributes by event or events to give a historical perspective of the weather being evaluated. This index can then be used to compare response costs to weather events of varying intensities. Unfortunately, the intensity of the weather event alone doesn’t give the full picture of the challenges of responding to that event. The true “total” cost of [responding to] a winter event is affected by a combination of the severity, timing and location of the winter event, along with its effect on the surface transportation system and area traffic. The purpose of this research project is to determine those impacts, quantify them, and develop a factor that can be applied to a winter severity index value to take into account the timing, location and underlying effects of those winter events and to normalize the events for reporting purposes.
