限速条件下高速铁路列车追踪间隔时间研究

Study on Tracing Interval Time of High-speed Railway Trains under Speed Restriction

列车追踪间隔时间一般分为出发追踪间隔时间、区间追踪间隔时间和到达追踪间隔时间。在分析计算无限速条件下列车追踪间隔时间的基础上,对区间限速条件下列车追踪间隔时间的确定进行解析,通过分析发现限速值和限速区段长度是影响列车追踪间隔时间变化的决定性因素。运用Opentrack软件,从定量方面对列车追踪间隔时间进行动态仿真检算,研究得出不同限速值和限速区段长度对列车追踪间隔时间产生影响的有关结论。

Train tracing interval time general divides into departure tracing interval time, section tracing interval time and arrival tracing interval time. Based on analyzing and calculating train tracing interval time under no speed restriction, this paper analyzes the determination of train tracing interval time under the restriction, through analyzing, the determining factors influencing the change of train tracing interval time is found are the speed restriction value and the length of speed restriction section. By using Opentrak software, the dynamic simulation calculation is taken on train tracing interval time from the aspect of quantity, the result gets the relative conclusions on influence of different speed restriction value and the restriction section length on train tracing interval time.
