Abstract:

A research project was initiated on behalf of the Colorado Department of Transportation (CDOT) and Transportation Avalanche Research Pool (TARP) to develop a metric for measuring the performance of highway avalanche management programs. The metric is meant to support resource allocation and other management decisions made by avalanche programs while also enabling use in an enterprise transportation asset management program. The performance metric developed is intended to supplement and extend the industry- standard Avalanche Hazard Index (AHI) by incorporating public safety measures, highway worker safety, avalanche worker safety, avalanche control method(s), avalanche control frequency and impacts to the travelling public (Road closure frequency, length, time of day, etc.).The resulting risk-based metric considers a combination of level of service, public safety, and worker safety with particular emphasis on the exposure of workers to dangerous maintenance and mitigation activities. The performance metric can be applied at the individual avalanche scale or to a group of avalanche paths.
