Abstract

Effective real-time snow and ice control operations require a timely initial call-out. A timely initial call-out is one that mobilizes the workforce slightly prior to the onset of hazardous road conditions. In order to estimate the onset of hazardous road conditions, the snow and ice control decision makers use available physical and meteorological information. New technologies are developed that could provide better information, thereby improving the ability to make timely initial call-outs. A systematic methodology for evaluating the benefit of additional information used in snow and ice control initiation is presented. The purposed methodology compares reduction in the direct and indirect costs of the call-out, attributable to the new information, to the cost of acquiring the information source. The methodology is implemented to evaluate road weather information systems for the Indiana Department of Transportation.
