越行列车组中待避列车停站时间有效性研究

Study on the Stop Time Efficiency of Overtaken Train in an Overtaking Train Group

列车间发生越行时,待避列车在站停时存在理论最优值,其实际停时与理论最优值间的比值反映了停时的有效性及列车运行图编制质量。分析四显示自动闭塞条件下待避列车停站时间波动范围,在此基础上根据越行列车到达越行站的理论期望时刻,给出待避列车在站有效停时的计算方法,并根据满意度理论构建待避列车停时满意度函数来评价待避停时有效性。以遂宁—三汇镇区段列车运行图为例进行验证,结果表明列车运行图的平均待避停时满意度均值为0.39,越行方案有待进一步优化。

When trains overtake each other, there is a theoretical optimal value of the overtaken trains＇ stop time, where the ratio of real-case stop time and theoretical stop time reflects the stop efficiency and train working diagram quality. This paper analyzes the stop time range of the overtaken train in the four-aspect automatic block system, where the calculation method for effective stop time is put forward with the theoretically expected arrival time of the overtaking train being taken into account, and a stop time satisfaction function is constructed to evaluate the stop time efficiency using satisfaction theory. As an example, the train timetable of Suining-Sanhuizhen section was analyzed, and the results show that the average stop time satisfaction value was 0.39, which means a further optimization of the overtaking plan should be applied.
