摘要
灵活编组模式通过运力供给和客流需求的高度匹配,为提高城轨运营服务质量提供了新的解决方案。在系统分析影响灵活编组方案编制的限制因素基础上,从提高乘客候车时间均衡性的角度,针对大小交路运营模式下小交路外围区段乘客候车时间过长等问题,提出考虑灵活编组方案下的编组数量优化方法,并从不同灵活编组方案中确定乘客候车时间均衡性的最优方案。算例验证结果表明:在组织灵活编组运营模式时,最优方案能在提高列车满载率的情况下减少乘客候车时间248.45 h,大小交路乘客平均候车时间同比差异率降低至41%,且能减少车辆走行公里数197.6 km,有效提升了乘客候车时间的均衡性。
Through the high matching of transport capacity supply and passenger flow demand,the flexible marshalling mode can provide a new solution to improve the service quality of urban rail operation.Firstly,the limiting factors were systematically analyzed.And then,from the perspective of improving the passenger waiting time equilibrium,in view of the problems of too long waiting time of passengers in the outer sections of the small crossing road under the operation mode,the optimization method of the marshalling number and the passenger waiting time calculation formula of the flexible marshalling scheme was proposed,and how to select the equilibrium optimization scheme from different flexible marshalling schemes was discussed.Finally,the example verification results show that that under the flexible organization of marshalling mode,the optimal scheme can improve the train full load rate,and reduce the passenger waiting time of 248.45 hours,and shorten the size of passenger average waiting time to 41%,and reduce the vehicle travel kilometers by 197.6 km,and effectively improve the equilibrium of passenger waiting time.
