摘　　要：列车追踪间隔时间是影响高速铁路通过能力的重要因素,除设备因素外,追踪间隔时间也受列车运行时空轨迹影响。以足够小的到达和区间追踪间隔作为严格约束,以最短区间运行时分为目标,提出了准移动闭塞条件下的列车运行时空轨迹优化模型,为在列车最优时空轨迹基础上分析追踪间隔时间影响因素及压缩措施提供支撑。以上海虹桥站为例,进行数值计算实验,验证所提出方法有效性;分析了后行列车进站信号再开放过程和线路条件对追踪间隔的影响规律。结果表明:该方法能够通过列车时空轨迹优化,以很小的区间运行时分代价实现追踪间隔时间压缩,实验场景中的最佳结果算例在区间运行时间延长小于3%的情况下,将到达追踪间隔时间压缩至135 s。Headway between trains is significant for the capacity of high-speed railway.The value of it is determined by high-speed railway facilities as well as time-space trajectory of the train.Under the condition of quasi-moving blocking mechanism,a mixed integer linear program model was developed to optimize the space-time trajectory of adjacent trains.In such a model,strict constraints of arrival headway and section headway were employed,with minimum total travel time of trains as the objective,which provided support for the analysis of the influencing factors of headway time and headway compression measures based on the optimal time and space trajectory of the train.Numerical experiments were conducted using the data of Shanghai Hongqiao Station to verify the effectiveness of the proposed method.The influences of the signaling time of successive train and railway technical condition on the headway were analyzed.The results show that this method can realize the compression of headway at a very small cost of running time by optimizing the time-space trajectory of the train.One impressive instance shows that the optimized train trajectory could help to achieve a 135 s headway on the test railway line,and cost only less than 3%of extra train travel time.
