摘要
介绍了轨道交通列车运行安全距离的概念,并对安全距离的影响因素进行了定性分析。结合移动闭塞条件下列车间最小追踪间隔模型,对移动闭塞中安全距离进行仿真研究。研究结果表明,安全距离是影响列车追踪间隔的主要因素,且在列车最高速度一定的情况下,列车最小追踪间隔时间随安全距离的增大而增大,基本呈线性关系。
The concept of safe distance is introduced and the influential factors are analyzed in the paper. According to the minimum headway model between trains in the con- dition of moving block, the simulation of safe distance is carried out. The result shows that safe distance is the main factor to influence the train headway. When the maximum train speed is determined, the minimum headway increases linearly with the increase of safe distance on the whole.
