Abstract: Snow accumulations and low visibility due to snow drifting is often a reason for temporary or seasonal closing of mountain highways. Safety devices like roadside safety barriers and snow fences, in addition to roadside snow build up, can increase these problems. This paper presents numerical simulations of snow drift over a road, with and without safety barriers on the roadside. The results from the simulations indicates that the numerical snow drift model can be used to improve the design and placement of safety barriers and to evaluate road design. The numerical snow drift model was calibrated against field measurements by Masao Takeuchi. Some details from the numerical modeling are also given.
