Upgrade of Signaling System on the Rapid Transit Systems

In this paper, discuss the upgrade system for an old type and extend to new line system of signaling at Taipei Rapid Transit Systems (RTS). Since the track circuits of fixed block are utilized the frequency loops and audio frequency track circuits of train position detected on the automatic train protect system. At present, Neihu line is the new extension construction of Muzha line, due to the new singling system as Communication Based on Train Control (CBTC) has use the new system and upgrade with revenues service system on the Muzha line. How do check and integration between old and new type systems to combination and compatible for the train running of Automatic Train Control (ATC) system shall importance issue. The CBTC system is used the simply construction technology with application to upgrade at Metro systems. In theme also comparison between fixed blocks and moving blocks circuits for conception of design in the Taipei RTS, and study of CBTC system technology manipulate on the system upgrade. Key-Words: CBTC, moving block, intelligent transportation, intelligent vehicle, signaling.
