Auxiliary stopping area (ASA) is the necessary emergency facility for train safety of the normal high-speed maglev. The study addresses the ASA layout problem of the high-speed maglev operated bidirectionally on single track. First, an optimization model of the ASA layout for unidirectional double-track lines considering train safety, operation efficiency, and construction cost is established, and two basic methods of the ASA layout are investigated based on the distance demand characteristic of ASAs. Then, the ASA layout problem of bidirectional single-track lines is analyzed, and an ASA two-way coordination layout algorithm (ASA-TWCLA) is proposed. Finally, a numerical experiment is carried out. The results suggest that under the premise of train safety and operation efficiency, compared with using the basic methods separately on the two directions, adopting the ASA-TWCLA algorithm can obtain a more economical ASA layout scheme for the same scenario.

单轨双向高速磁悬浮辅助停车区布置方法

辅助停车区（ASA）是正常高速磁悬浮列车安全的必要应急设施。该研究解决了在单轨道上双向运行的高速磁悬浮列车的ASA布局问题。首先，建立了考虑列车安全性，运行效率和施工成本的单向双线客车ASA布局优化模型，并根据ASA的距离需求特性研究了两种基本的ASA布局方法。然后，分析了双向单轨线的ASA布局问题，并提出了ASA双向协调布局算法（ASA-TWCLA）。最后，进行了数值实验。结果表明，在列车安全和运行效率的前提下，
