不同运行规则下区间列车运行安全性及效率研究

列车区间运行安全是列车运行安全中极为重要的部分,而列车在区间运行的安全性及效率与运行规则密切相关。将闭塞分区及与其配套的通过色灯信号机结合在一起,建立区间模型,给出列车在区间运行的安全性要求,定义列车在区间连续追踪运行的安全度,介绍列车在区间运行的全部3种运行规则及相应的区间阻塞状态。在此基础上,定量计算3种规则的安全度。基于安全性和效率,对列车运行规则进行深入研究,结果表明,3种规则效率相当,规则1安全性最优。

Research on Safety and Efficiency of Train Operation in Section Based on Different Operation Rules

The safety of train operation in section is a key part of train operation safety,and safety and Efficiency of train operation in section are closely related to the section operation rule.Block section and its related signal were combined,a section model was built,and train operation safety requirements in section were proposed,the safety degree of train continuously tracing each other in section was defined,finally,introduction to all three rules of train operation in section and their related section block situation was made.On the basis of above-mentioned work,quantitative calculation of the safety degree for three rules was made,and deep research was carried out on the rules of train operation from safety and efficiency angles.The result shows that all three rules have the same efficiency with different safety degrees.And rule No.1 is safest.
