Abstract

Optimizing crowd regulation through the setting of diversion railings at the bottleneck of subway stations is a precise and effective strategy to improve the traffic efficiency and safety of high-density crowds. The existing work mainly focuses on setting fixed railings based on management experiences, which lacks dynamic regulation strategies in the passage process. To address this issue, an automatic regulation optimization method for crowd under railings is provided based on the model predictive control. System identification methods are used to model the obtained flow data at bottlenecks based on the MassMotion, and a model predictive control system for railings, therefore, is constructed, with the length of the railing as the control input and the crowd density as the controlled object. Regulation commands have characteristics of simplicity and clarity, which can effectively intervene in the traffic state of high-density crowds, striking an optimal balance between safety and efficiency.
