철도신호시스템 교체에 따른 운행 시나리오 도출에 관한 연구

초록

The railway signalling system plays an essential role in the headway and routing control for a safe andefficient train operation. The reliable and safe operation of the system is very important because the failure of therailway signalling system can lead to the collision, derailment, or unexpected stop of a train. So far, the conventionalwayside signal mode (ATS: Automatic Train Stop) has been generally used as the railway signalling system. However,this system is highly linked to a risk of major accidents resulted from human mistakes such as missing a signal orcareless control of train speed. Accordingly, the onboard signal mode (ATC: Automatic Train Control) as an alternativeof ATS has been recently introduced and applied to transmit effectively the information on speed control of a train byusing computers and communication equipment. In the process of replacing the obsolete signal system, it is necessary toswitch over the system while providing passengers with normal services. Therefore, the integration of a railwaysignaling system compatible for both ATS and ATC and its interface is discussed in this study. In particular, theimplementation scenario required for operation planning of the integrated system was designed, and the results as well aseffects of its applicability test were also presented.
