The bus-bridging service has always faced problems in severe emergencies or catastrophes that require the large-scale evacuation of passengers. This paper provides an alternative evacuation scheme which uses the urban bus network in the case of common metro service disruptions; this is modeled by minimizing the total cost of the affected metro passengers, through jointly selecting the bus lines and frequencies. The uncertain recovery time of the service disruption and the heterogeneous risk-taking behavior of the affected metro passengers are incorporated in the scheme. Therefore, we build a linkage between the evacuation service design and the risk-taking behavior of passengers. A heuristic algorithm is proposed to calculate the optimal evacuation scheme. A numerical experiment using a real-world network is conducted to illustrate the validity of the model and algorithm.

在严重的紧急情况或灾难中，公交桥服务始终面临着需要大规模疏散乘客的问题。本文提供了一种替代疏散方案，在地铁服务中断的情况下使用城市公交网络。通过共同选择公交线路和班次，将受影响的地铁乘客的总成本降到最低，以此为模型。该方案包括服务中断的不确定恢复时间以及受影响地铁乘客的异类冒险行为。因此，我们在疏散服务设计和乘客的冒险行为之间建立了联系。提出了一种启发式算法来计算最优疏散方案。
