The purpose of the present study is to develop a new type snow fence with induced snow plate in the form of circular arc airfoil for the prevention of snowdrifts and improving visibility on roadways. The design is in accordance with aerodynamic principles, and its performance is evaluated in a wind tunnel in which natural snow is used to simulate blowing-snow. In general, the snow fences are classified into two types, i.e., snowbreak type and snow blowing-off type. The developed snow fence in present study has two performances of which blowing-snow is broken at the bottom part and is blowed from the top part of snow fence. An optimum configuration of the induced snow plate which forms the top part of the snow fence is designed for the prevention of blowing snow at the leeward side on roadway. Consequently, the developed new type snow fence with the induced plate in the form of circular arc airfoil has high performance in preventing snowdrifts and improving visibility in comparison with the conventional snowbreak fence. In especial, the performance of the newly developed snow fence is in most cases preserved without burying itself in snowdrifts which often occurs in the conventional snow fence when a large-scale blowing-snow occurs.
