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。
This paper analyzes the distribution pattern of the operating line in the train operation diagram of the passenger dedicated line, and uses the heterogeneity to describe the correlation between the departure time interval and the departure time interval between the train operation lines. The formula for calculating the heterogeneity of the train operation diagram is given to quantitatively analyze the train Run graph dynamic performance. The rationality of the calculation formula of heterogeneity degree by computer simulation is verified through the adjustment process of train operation diagram. Taking the distribution patterns of three kinds of typical trains in Wuhan-Guangzhou Passenger Dedicated Train operation as an example, the calculated train run-out heterogeneity is 0.64, 0.68 and 0.11, respectively. The simulated dynamic performance of the train operation diagram is in turn worse, Worst and best. It can be seen that the lower the heterogeneity of the train operation diagram is, the higher the dynamic performance is. The formula for calculating the heterogeneity of the train operation diagram is reasonable.
