Abstract

Presently metro in our county 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 the train location without using the track circuits. It has many advantages in aspects of signalling equipments build-up and maintenance. This study investigated examples of radio communication system and applicable standard norms in other countries. And it also reviewed the suggestion for the establishment of radio frequency and radio network to be considered for application train control system by radio under Korean metro environment.
