[Objective] At the initial stage of urban rail transit projects, it is essential to design a traction calculation simulation platform to accurately evaluate the operational indicators of the signaling system and meet engineering requirements. [Method] Based on a practical ATO (automatic train operation) algorithm, a platform is designed to assess indicators such as operating speed and headway in urban rail transit signaling systems. A simplified CBTC (communication-based train control) system is simulated, incorporating operational planning formulation, movement authorization computation, safety control model outputs, and the automated generation of traction calculation CAD (computer-aided design) drawings. These drawings include details on speed curves, track gradients, track layout, and headway intervals. [Result & Conclusion] The integration of simulation platform and train control algorithm library is successfully achieved. Key parameters of the ATO algorithm are effectively extracted through interface design, facilitating flexible adjustments for different project applications. The platform architecture comprises three main modules: data management, logic processing, and graphical display. It is equipped with an intuitive and user-friendly interface that supports operations such as configuring operational parameters, setting train and track parameters, calculating headways, and displaying speed-distance curves. This design enables users to directly control each stage of the process. Although the simulation running cycle can be adjusted as needed, the computation cycle of the dynamics model remains consistent with real-world operations.
