A Study on Standardization and Functional Analysis for Urban Rail Transit Public Addressing System

도시철도 방송시스템의 표준화를 위한 기능분석 및 표준사양 도출 연구

It is expected that standardized framework for urban rail transit system will contribute to more convenient and safe traffic service and ensure higher reliability and availability of urban rail transit rolling stock and infrastructure. Information and telecommunication system in urban rail transit consists of various subsystems, such as radio communication system, digital transmission system, integrated monitoring system and public addressing system and its standardization will be implemented based on these subsystem. Public addressing system is to provide information related to operation and emergency for passengers and operators. In this paper we suggest draft criterion of public addressing system for urban rail transit through functional analysis and comparison on the present state of the system.
