Resource Sharing and Interoperability of Signaling System in Urban Rail Transit

The paper introduces the basic forms to realize resource sharing in urban rail transit, and the essential conditions and methods to fulfill interoperability among signaling systems. There are several forms to realize resource sharing in urban rail transit, including sharing in technology, MMI and operation, maintenance equipment, human resource, maintence technology, and simulation training resource, The basic conditions of interoperability for signaling system are consistent signaling model, consistent system structure and functional partition, compatible ground-train commnuication system, consistent or compatible train location technology, consistent design and requirement of ATP safety control mode, consistent train operation mode, uniform interface between signaling system and vehicle, proper frequency and interface allocation for signaling and PIS system, etc. The basic means of interoperability for signaling system are selecting the same signaling system from one manufacturer, taking general on-board signaling system and realizing standard interoperability for signaling system, etc. The paper also presents the progress in resource sharing and interoperability in foreign mass transit.
