前继列车晚点条件下换乘客流的接续方案优化OA北大核心CSTPCD

In addressing the challenge of train timetable adjustments due to disruptions in train opera-tions, this study delves into the optimization of transfer passenger flow connection schemes under the conditions of delays in the preceding train. The optimization objectives involve minimizing the impact of transfer passenger flow and in-train passenger flow, prompting corresponding adjustments to the train timetable. In instances where the preceding train is delayed, considering scenarios where transfer passenger flow can shift to the original connecting train or other trains meeting transfer conditions, a multi-objective model is established. This model aims to minimize the overall passenger delay and reduce the number of passengers failing to transfer, ensuring optimal train operation adjustments while guaranteeing successful transfers. Effectiveness of the model is validated using examples from the upward sections of the Beijing-Shanghai high-speed railway and the Zhengzhou-Xuzhou high-speedrailway. The results show that when considering the restrictive relation between the total train adjust-ment time and the failure cost of transfer passenger flow, enhancing the success of transfer passenger flow can be achieved by extending the train timetable adjustment time. When considering the restrictive relation between the total passenger delay and the failure cost of transfer passengers, sacrificing some transfer passengers can reduce the overall passenger delay on the train. In addition, when available seats on other connecting trains are significantly reduced, the scheme tends to adjust the arrival and departure times of the original trains to avoid a large increase in the number of passengers failing to transfer.
