Carrying Capacity of High-Speed Railway Large Passenger Station Based on Route-Lock-Section-Release Mechanism Based on Centralized Traffic Control

摘要:

车流结构的变化和车流量的攀升对高速铁路大型客运站车站通过能力利用分析和挖掘提出迫切需求。我国高速铁路车站基于调度集中控制（CTC）模式下采用进路分段解锁，相比传统的进路一次性解锁，对车站通过能力有进一步挖潜的可能。建立车站通过能力仿真模型，车站基础设施布局做为底层数据，列车运行图做为输入条件。模型基于CTC工作原理，分析了单列车在车站内的运行过程以及多列车之间的互相影响，用于确定列车在站内的相关时间参数；计算道岔、股道等行车设施通过能力利用率，识别限制能力的关键设施，通过仿真模型计算车站通过能力并输出结果。研究结果表明，相比于传统车站通过能力计算方法，计算机仿真方法能微观化地模拟进路分段解锁过程，精细化分析相关影响因素并计算车站通过能力，有助于从车站通过能力整体提升的角度支持形成设备改造、车站作业方案的优化建议。

Abstract:

Changes in traffic flow structure and the increase in traffic volume have created an urgent need for the analysis and exploration of the utilization of throughput capacity of large high-speed railway passenger stations. For high-speed railway stations in China， the adoption of the route-lock-section-release mechanism based on centralized traffic control （CTC） system offers potential for further enhancing the throughput capacity of stations， compared to the conventional route-lock-route-release mechanism. A simulation model for the throughput capacity of stations is established， with station infrastructure layout as the underlying data and train working diagram as the input condition. Based on the CTC performance mechanism， the model first analyzes the operation process of a single train in the station， as well as the interactions between multiple trains to determine the relevant time parameters of trains in the station， calculates the capacity utilization rate of traffic facilities such as switches and tracks， identifies key facilities that limit the capacity， computes and outputs the throughput capacity of stations. The results show that compared with the traditional throughput capacity calculation method， the computer simulation method can simulate the route-lock-section-release mechanism in a more microscopic way. This method can analyze the related factors and calculate the throughput capacity in detail， which is helpful to support the optimization of facility upgrading and station operation plan from the perspective of the overall improvement of the throughput capacity of stations.
