통신기반 열차 위치 검지 및 성능평가에 관한 연구

There have been numerous methods devised and used throughout the years for train position sensing and determination but there is a still a lack in the reduction of headway and maintenance costs. In order to overcome these limits CBTC(Communication Based Train Control), which is a next generation wireless communication system, is gradually increasing in use. This study attempts to offer a quantitative performance evaluation result on whether or not the position sensing error satisfies a given specification when the position of a train is sensed regardless of where it may be at any given instant using CBTC.
