Connotation and Model Analysis of Rail Transit Interconnection and Interoperability under Multi-Network Integration Background

[Objective] At present, the regional rail transit system in China has entered a new stage of multi-network integrated development, and its operation and management also presents new characteristics of multi-level, multi-dimensional collaborative management and optimization. Therefore, clarifying the interconnection and interoperability modes among different levels of rail transit within the region is the prerequisite and foundation for all aspects of operation management work. [Method] Through the investigation, analysis and summary of the development status of typical regional rail transit systems around the world, the connotation of the interconnection and interoperability among multi-level rail transit within the region under the multi-network integration background is defined. From the perspectives of physical network connection, compatibility of facilities and equipment, coordination of transportation organization and collaborative operation management, the interconnection and interoperability modes and their characteristics are systematically reviewed. And in combination with the actual situation and development trends, the applicability of various interconnection and interoperability modes is discussed. [Result & Conclusion] On the basis of the connection and transfer mode, the improvement and coordinated optimization of connection forms and operation plans is the most suitable interconnection and interoperability mode scheme for the rail transit systems in major metropolitan areas in China under the existing planning and construction foundation and development trends.
