A Study on Decision method of block section

폐색구간 결정을 위한 기법연구

In railway train operations, a braking distance between two trains must be controlled on their speeds to avoid rear end collisions. The distance is decided by some parameters such that propulsion and braking performance of trains, gradient and etc. When determining this block distance, it is important to consider the two aspects that safety insurance at train running and increase of train running frequency. In this paper, we showed a methodologies of equiblock by consideration gradients and calculated optimal block speeds on the basis of the equivalent block distance.
