Under inclement weather conditions such as rain and snow, the wheel-rail adhesion characteristics of urban rail transit systems significantly deteriorate, posing failure risks to the overspeed protection function of Automatic Train Control (ATC) systems. To enhance the global robustness of ATC systems, this study investigates optimization strategies for ATC overspeed protection control under low-adhesion conditions. First, the operational mechanism of ATC overspeed protection is systematically analyzed through the Safety Braking Model, Guaranteed Emergency Braking Rate (GEBR), and adhesion braking principles. Second, by examining the mismatch between the rigid GEBR setting in engineering practice and the stochastic fluctuation of adhesion coefficients in actual operations, this research reveals a chain failure mechanism: “adhesion degradation→braking performance reduction→GEBR dynamic mismatch→safety threshold breach in braking distance”. Finally, a MATLAB-based simulation model integrating dynamic wheel-rail adhesion characteristics is developed for ATC overspeed protection, with validation through specific accident cases. Results demonstrate that compared with existing rain-snow mode protection strategies, the proposed multi-objective collaborative optimization dynamic control strategy achieves refined coordination of GEBR values and system ceiling speed, effectively balancing train braking safety and system operational efficiency in low-adhesion environments.
