地铁突发故障下的公交接驳和客流管控协同模型

A coordinated model of bus bridging and passenger flow management and control inresponse to urban metro failure

地铁发生突发故障后,通常采用接驳公交车疏散滞留乘客。然而,当大量乘客被接驳公交车运送到折返站时,很可能会造成折返站的乘客滞留。为了降低公交接驳阶段和乘客换乘阶段全过程的乘客延误,构建了地铁突发故障下的公交接驳和客流管控协同模型;通过求解模型得出乘客延误最小的应急管理方案,并对影响模型性能的相关因素进行敏感性分析。以深圳地铁3号线为例,对比传统模型和协同模型的性能。研究结果表明:协同模型在降低乘客延误方面比传统模型拥有更好的性能,协同的管理方案可以有效降低乘客延误;当所有乘客都能被疏散时,增加公交车数量对降低乘客延误的效果甚微;列车小交路模式启动时间和列车发车间隔对降低乘客延误起着重要作用。

Shuttle buses are generally sent to evacuate stranded passengers during urban metro disruptions.However,when a large number of passengers are transported to the turnaround stations by shuttle buses,it is likely to cause the passengers to wait for the turnaround station.In order to reduce the passenger delay in the whole process of bus bridging and train re-boarding,this paper proposed a coordinated model of bus bridging and passenger flow management and control in response to urban metro failures.The emergency management plan with the minimum passenger delay was obtained by solving the model,and the sensitivity analysis of relevant factors affecting the performance of the model was performed.Taking Shenzhen Metro Line 3 as an example to compare the performance of the traditional model and the coordinated model.The experimental results show that the coordinated model has better performance in reducing passenger delay than the traditional model and the collaborative management scheme can effectively reduce passenger delay;when all passengers can be evacuated,increasing the number of buses has little effect on reducing passenger delay;The time when urban metro starts tooperate in a short turning mode and the train departure interval play an important role in reducing passenger delay.
