도시철도에서 무선을 이용한 열차제어시스템 적용방안 연구

Presently metro in our country has higher rate of passengers as a public transportation of urban area than other transportations. And road is under very restrictive condition to be expanded in many aspects because the streets are completely choked. Therefore increase of capacity in metro and reduction of headway has been seriously required and utmost efforts has been taken by related fields to meet the requirements. The concept of CBTC system came out from this background. CBTC system can be implemented to detect t location without using the track circuits. It h advantages in aspects of signalling equipments and maintenance. This study investigated exa radio communication system and applicable norms in other countries. And it also revie suggestion for the establishment of radio freq radio network to be considered for application control system by radio under Korean metro env
