Abstract: Objective Traditional signaling systems manage trackside resources using routing-based methods and calculate movement authority accordingly. In contrast, the TACS（train autonomous circumnavigation system） manages resources from the perspective of train itself, resulting in higher efficiency. To enable train interoperation across lines with different signaling systems, it is necessary to propose a new resource management scheme based on the integration of TACS and CBTC（communication-based train control） system. Method The trackside resource management primarily involves the stages of wayside resource request, interlocking condition checking and directional locking, and signal logic release. Based on the functions of trackside resource management equipment, resource competition and deadlock scenarios are examined. The management conditions and content for each stage are elaborated from the perspectives of shared and exclusive resource characteristics. Result ＆ Conclusion The proposed resource management scheme utilizes the directional attribute of trackside resources and associated interlocking conditions to effectively prevent risks such as head-on and side collisions. Compared to traditional train operational control systems, the safety in new resource management scheme is significantly enhanced. In combination with signal control, the scheme ensures compatibility between TACS and CBTC systems. It also effectively avoids operational deadlocks caused by concurrent train tasks at the same turnout, thereby ensuring operational efficiency.
