Abstract
This paper describes characteristics of visual range attenuation in blowing snow in relation to motorist vision. Visual range V is related to wind speed U according to V = AU-5 with the A coefficient changing in response to snow availability. A lower limit for visual range is described with A =1.1 X108 m6 s-5. An operational monitoring system used on Interstate Highway 80 in Wyoming demonstrates how real-time computer analysis of photometric data can be used to determine the A value, interpret visual range in terms of vehicle operation, and provide automated traffic operations decisions.
