Abstract: ［Objective］ Current urban rail transit system faces issues such as information silos and low coordination efficiency, which hinder the ability to meet the demands for digital transformation, high safety, and high automation level. To address these problems, an in-depth study of the efficient collaboration and minimization of electromechanical systems is required. ［Method］ The current state of urban rail transit systems is analyzed, including system composition, interface status, and case studies of coordination minimization. A development plan and implementation path for system coordination and minimization are proposed. ［Result & Conclusion］ With the advancement of digital transformation and smart urban rail transit construction, system coordination and minimization will become important means to enhance the efficiency, service quality, and safety of urban rail transit, offering broad application prospects.
