| 摘 要： | 根据地铁系统的特点,分析追踪列车间隔时间与列车区间运行时间和停站时间的关系。在非晚点情况下,根据列车区间运行时间和停站时间与图定时间的偏离,建立描述列车运行图缓冲时间与干扰概率、随机干扰变量之间关系的概率模型。采用适当的分布函数对随机干扰变量进行分布拟合,计算不同干扰水平下的缓冲时间。以某条地铁线路为例,将其1 d的实际列车区间运行时间和停站时间作为基础数据,采用给出的模型和计算方法,计算得到不同干扰水平下的最小缓冲时间,用于确定地铁列车运行图合理的追踪列车间隔时间。

| Abstract: | Based on the characteristics of metro system,the relationships among the train headway,the running time in section and the dwell time were analyzed. Under the non-delay circumstance,the probability model describing the relationships among the buffer time of the train diagram,the disturbance probability and the stochastic disturbance variables was built according to the deviation of the train running time in section and the dwell time from the time fixed in the train diagram.After the distribution fitting of... |
