摘要
为了解决地铁列车运力不足,缩短列车追踪间隔,提出了新型列控系统、相对移动闭塞和协同运行三者相结合的方法,构建了列车通信协同运行模型。在该模型下,精细化前后列车冲突区域,对正线和站后折返最小追踪间隔分别优化建模,提出缩短追踪间隔的行车策略。经实际线路仿真计算,相比基于通信的列车运行控制系统(communication based train control,CBTC)列车通过能力提升了32.3%,且4A编组可以满足79.9 s的行车间隔。考虑缩短行车间隔对运营效能的影响,将运营效能量化为运输率、满载率、单位能耗、等车时间,对不同行车方案进行评估。结果表明,对于单向小时断面客流量小于6.4万的线路,通过调节行车间隔,4A编组在满足满载率下,比6A、8A编组能耗更小,等车时间更短。
In order to solve the problem of subway train capacity shortage and reduce the train headway,a method combining a new train control system,relative mobile blocking and cooperative operation is proposed.A cooperative operation model for train communication is constructed,which focuses on refining the conflict area between the front and rear trains.Additionally,the model optimizes and models the minimum headway of the mainline and the turnaround after the station.A driving strategy is also proposed to further shorten the headway.Through simulation calculations on an actual line,it is found that the train passing capacity improves by 32.3%compared with the Communication Based Train Control System.Furthermore,the 4A marshaling can achieve a headway of 79.9 s.Considering the impact of shortening the headway on operational efficiency,the operational efficiency is quantified as transportation rate,full load rate,unit energy consumption,waiting time,and different driving schemes are evaluated.The results indicate that for lines with a one-way hourly passenger flow of less than 64000,the 4A marshaling scheme consumes less energy compared to the 6A and 8A marshaling schemes,and reduces the waiting time when the full load rate is satisfied.
