Regional Rail Transit Electronic Map Data Management Scheme for Intercity Railway Through-operation

Abstract

[Objective] In the new round of metro politan rail transit integration construction, enhancing train through-operation is crucial for reducing passenger interchange time. Cross-system intercity railway through-operation requires efficient train operation and scheduling management, and unified management of electronic map basic data for different lines is the key. [Method] Based on the practical demand for unified management of regional multi-system line electronic map data, the current application status of electronic maps in CBTC (communication-based train control) and CTCS (China train control system) systems is investigated. The differences in information content, acquisition methods, and transmission media of electronic maps for different signaling systems are comparatively analyzed. A regional rail transit line data management system based on a three-tier architecture comprising a regional center, local control platforms, and local workstations is proposed. Additionally, the data storage structure, data downloading method, and platform software features of the system are detailed. [Result & Conclusion] Establishing a unified management system for electronic map basic data of different lines within a region can better serve the comprehensive development of regional rail transit data synthesis, resource sharing, and management-control integration, which ensures integrated linkage command of regional rail transit, forms a multi-tiered comprehensive transportation system, and facilitates the high-quality development of regional rail transit integration in megapolitan areas.
