Key Points in the Design of Regional Rail Transit Signal System of Beijing-Tianjin-Hebei and Application of New Technologies

To clarify the concepts for the construction of the signal system of Beijing- Tianjin- Hebei integration in pre planning and research stages,the key points of the design and new technologies are studied thoroughly. This paper analyzes the present application of the Beijing- Tianjin- Hebei regional rail signal system,and compares various rail transit signal modes in view of such three aspects as interconnection requirements, operation functional requirements and technological integration. The analysis addresses compatibility in system mode selection,technological innovation to meet operational demand and localization in technological integration. In addition,the application of new technologies of automatic train operation,train ground communication and Beidou satellite navigation are analyzed.
