System Function Requirements of Intercity Railway CBTC in Shenzhen Metropolitan Area

Compared to the existing urban rail transit CBTC (communication based train control), the intercity railway CBTC in Shenzhen metropolitan area is quite different in terms of train operation speed level, interconnection function and system architecture. Currently, relevant standards for intercity railway CBTC have not been issued in China. By studying the transportation needs of intercity railways in Shenzhen metropolitan area, the adaptability of operation intervals in intercity railway CBTC, train control at 160~200 km/h speed, vehicle-wayside communication and interconnection is analyzed. Through the design of intercity railway CBTC system architecture in Shenzhen metropolitan area, the requirements of CBTC system innetworking, high-speed and automation are proposed. It is suggested that technical specifications of CBTC standard system for the intercity railway in Shenzhen metropolitan area should be studied and compiled as soon as possible, so as to provide standards and technical guidance for the construction, acceptance, operation and maintenance of the intercity railway signaling system.
