Integrated criteria and systematic process for wind barrier installation in strong crosswind regions along Korean expressways

Korea’s expressway network has seen immense expansion in the last decade with connections being made to all provinces and cities. However, on expressways passing through valleys and coastal areas, many stretches are exposed to strong crosswinds. In these regions, sideslips between vehicle tires and the road surface can lead to serious traffic accidents. To reduce accidents, design criteria for the moving speed limit and proper countermeasures such as wind barrier provisions are required. For this reason, there is a need for integrated criteria and a systematic process that can be incorporated into the Korea Expressway Corporation’s policy. In this study, the safety criteria for vehicles under strong crosswinds were established. The design parameters for wind barriers were obtained. This was followed by wind-speed measurements of strong local crosswind fields in all four seasons, which were compared with long-term wind-speed data from the Korea Meteorological Administration. Finally, a systematic process for wind barrier installation was determined based on a probability analysis. This paper proposes integrated criteria and a systematic process for wind barrier installation in Korea.
