| 摘 要： | 分析客运专线列车运行图中运行线分布模式,采用异质度描述列车运行线之间的发车时间间隔和到达时间间隔的关联性,给出列车运行图异质度计算公式,用以定量分析列车运行图动态性能。通过对列车运行图实施调整过程计算机仿真验证异质度计算公式的合理性。以武汉至广州客运专线列车运行图3种典型列车运行线分布模式为例,计算得到的列车运行图异质度分别为0.64,0.68和0.11,仿真得到的列车运行图动态性能依次为较差、最差和最好。由此可知:列车运行图的异质度越低,其动态性能越高;给出的列车运行图异质度计算公式是合理的。

| Abstract: | The layout modes of train paths in PDL train working diagram were analyzed. Heterogeneity was adopted to describe the relationship between the departure time intervals and the arrival time intervals of train paths. Formula was presented for calculating the heterogeneity of train working diagram to quantitatively analyze the dynamic performance of train working diagram. The rationality of the heterogeneity formula was validated through the simulation on the implementation and adjustment process of train work... |
