Objective: With the increasingly complex electromagnetic environment in rail transit, the construction of electromagnetic spectrum maps can effectively enhance control over electromagnetic spectrum resources, for which purpose the research is carried out. Method: By summarizing the application areas and challenges faced by electromagnetic spectrum maps, three construction methods are detailed: spatial interpolation construction, parameter construction, and hybrid construction. Considering the electromagnetic environment characteristics of rail transit, relevant challenges and development trends are analyzed. Tailored to the electromagnetic environment characteristics of rail transit, a platform architecture for electromagnetic spectrum maps for rail transit is proposed. This architecture includes a global electromagnetic spectrum map, a local electromagnetic spectrum map, cognitive engine, data acquisition and storage unit, a priori information database, and a geographical location database along rail lines. Result & Conclusion: The construction of an electromagnetic spectrum map for rail transit is an effective method to optimize system resource utilization rate. Different construction methods are suitable for different scenarios and requirements. Through a welldesigned platform architecture, accurate perception and efficient utilization of the electromagnetic environment can be achieved, for addressing challenges such as the utilization of location information, heterogeneous network management, and meeting reliability requirements. The future development trends should focus on the application development of new technologies, data integration, and exploring new applications for electromagnetic spectrum maps.
