Paper Abstract

This paper describes characteristics of visual range attenuation in blowing snow in rela-tion to motorist vision. Visual range V is related to wind speed U according to V = A U-5 with the A coefficient changing in response to snow availability. A lower limit for visual range is described with A = 1.1.108 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.
