The Maglev travels at levitated status from the rail in some gab (about $8\sim10mm$). it make difference with the existing subway or the another LRV. The detection method of the train speed and the train position to be used at Maglev's signaling system differ with the existing subway or the another LRV's. so, the signal system construction of the new method is necessary. This paper describes the configuration and characteristic of the total signaling system (TTC/Wayside/Cab/Guide way system etc.) developed for Maglev, and the design concept of the signaling system based on the latest wireless LAN communication for driverless operation.

CBTC(Communication Based Train Control) System has many superior train control performances than conventional track-circuit-based train control system with higher train operation efficiency, and less installation and maintenance cost. It is expected that CBTC will replace the conventional train control systems in near future. As CBTC has different mechanisms from conventional track-circuit-based train control systems in identifying train positions, and communicating information between train and ground facility, we have to pay a earful attention to making the interface between CBTC equipments and other signalling devices. This paper provides the construction of the interface between CBTC equipment and other signalling equipments such as TTC(Total traffic Control) system. ATO. electronic interlocking devices.

Urban railway system that leads the urban public transportation enables the passengers to use the subway system safely and conveniently by indicating the destination of, status of approach of and other information on train through Train Destination Equipment(TDE), which is one of the important passenger services. The existing system is composed of Host Station Equipment(HSE) and operator panel that receives necessary input on train information from Total Traffic Control System(TTC), Local Station Equipment(LSE) that controls Train Destination Indicator(TDI) installed at each station, and Train Destination Indicator that ultimately displays train information to the passengers using the train system. This study aims to realize stabilized and reliable announcement system for destination of train by considering processing procedure and method of expression of inputted information of the existing system of notification of announcement of destination of train that can be applied in the RFID, which is the base technology of USN for which service expansion is easy, and to realize system that considers interface with USN and expandability with other facilities in the future.
