A study on the characteristics in the vicinity of the railway track

철도 선로 주변의 자연풍 특성에 관한 연구

Anemometers to examine the characteristics of the natural wind in the vicinity of the railway track has been installed in two spots, one at the Cheon-Asan station of the Seoul-Busan high-speed line, and the other at the Daechon station of the Changhang conventional railway line in 2006 to examine the characteristics of the natural wind around the railway track to estimate the actual wind speed acting on the train and to develop the wind gust model consisting with the Korean climate condition. The measured data shows that the instant wind velocity frequently exceeds the velocity of train speed restriction, 20m/s, and the actual wind velocities measured in the vicinity of the track are larger than the that measured by the Korean Meteorological Administration(KMA) because the anemometers are installed on the highly-elevated bridges.
