차량의 선진화에 따른 기존선의 곡선부 통과속도 향상에 관한 연구

Study for the advancement of vechilc's passing speed on the curve

After a lot of hard effort during last 50 years, we have been finally beared fruit of a high speed vehicle. But, A large percentage of the existing railways are actually being lasted it's last popularity because of the backward speed. The object of this research isn't supposed to make an effort for developing vehicle's speed with lower budget, but to evaluate it's efficiency. The time has come for upgrading train's lower speed with at the minimum of rail's changing. To solve this problem, we are describing that is how to control a transition curve of the railway.
