description [Objective] Unlike the existing CBTC (communication-based train control) system control mechanism, the ATC (autonomous train control) system achieves autonomous train operation by directly controlling wayside resources. To improve the operational efficiency of turnout segments, it is necessary to study the control algorithm of ATC system in turnout segments, using smaller granularity turnout safety zones as control resources for ATC system. [Method] The control algorithm of ATC system considers the track section as a shared resource, with turnout safety zones allocated separately for train use. A comparative analysis is conducted between ATC system and CBTC system in scenarios with single-slip turnouts and crossover turnouts, and simulation calculations are performed using real train control system and turnout parameters to improve the operational efficiency. [Result & Conclusion] Compared to the conventional interlocking algorithm of CBTC system, the control algorithm of ATC system for turnout safety zones performs better. In single-slip turnout scenarios, the maximum increase in the safety interval for train operation reaches 74.5%. In crossover turnout zone scenarios, the maximum increase in train turnout-passing time reaches 33.8%. By optimizing the system architecture and control algorithm, ATC system increases flexibility and efficiency, serving as an important direction for the development of the next generation train control system.
