Abstract: The service capacity of urban rail transit stations during peak hours is facing great challenges, and security checks, as an important link for inbound passengers, have become a pain point that restricts the inbound efficiency. Based on this, this paper constructs an evaluation system for the operational status of security checks, utilizes a simulation model of inbound passenger flow, and optimizes the configuration of station security checks in combination with differentiated security check modes, providing reference for the formulation of security check optimization plans for operators. The results indicate that the current operational status of security check of the station is poor, making it difficult to meet the inbound demand of passengers during peak hours. The optimization scheme based on differentiated security check mode can improve the inbound efficiency of passengers during peak hours by at least 14.0%, and significant improvements have been made in key indicator parameters that reflect the operational status of security check, such as maximum queue length, facility capacity matching degree, and inbound density index.
