摘　　要：高速铁路列车到达追踪间隔时间是制约列车追踪间隔时间的主要因素。为缩短列车到达追踪间隔时间,在阐述其定义的基础上,分析列车到达追踪运行过程中后车制动和前车进站运行、CTC系统作业的时空和时序关系。参照列车追踪间隔的定义,采用提前减速的方法,提出基于目标速度的列车到达追踪间隔时间的优化策略,根据前车进站后的运行时间、CTC办理接车进路时间与后车制动时间的大小关系,分2种情况建模分析列车追踪进站过程,推导出列车到达追踪间隔时间的优化算法。最后,用软件仿真分析不同线路条件、不同列车制动性能和不同咽喉区长度下优化后的列车到达追踪间隔时间,结果表明该策略能有效缩短高速铁路列车到达追踪间隔时间,从而为高速铁路缩短列车追踪间隔提供一定的参考。The train arrival tracking intervals are the primary factors restricting train tracking intervals on high speed railway.To shorten these intervals,the spatiotemporal and temporal relationships during the train arrival tracking were analyzed,focusing on rear train braking,front train station entry,and CTC system operation.Referring to the definition of train tracking intervals,an optimization strategy for train arrival tracking intervals based on target speed was proposed,employing the method of deceleration in advance.Modeling and analyzing train tracking and station entry processes in two scenarios,based on the relationship between preceding train station entry time,CTC route assignment time,and the following train braking time,led to the derivation of an optimized algorithm for train arrival tracking intervals.Finally,software simulations were conducted to analyze the optimized intervals under various line conditions,train braking performances,and throat lengths.The results indicate the effectiveness of this strategy in reducing high speed train arrival tracking intervals,offering insights for shortening train tracking intervals in high speed railway.
