摘要

城市轨道交通系统在运行过程中经常受到各种安全事故的干扰。因此,有效利用在途乘客信息,动态评估轨道交通系统在干扰下维持和恢复正常运行的能力(运行弹性),是轨道交通安全管理和应急响应的关键和前提。基于典型的作战中断场景,研究了多模式数据驱动的轨道交通作战弹性及其评价方法。本研究的主要贡献包括:基于历史数据获取乘客出行过程中的关键信息,量化系统的服务能力;提出了基于服务水平的面向城市轨道交通应急管理的运营弹性概念;运用弹性曲线分析安全事件中轨道交通服务水平的演化模式,强调运行弹性的相关性和动态性;构建了两阶段“中断-恢复”轨道交通运行弹性评价模型,并以杭州轨道交通为例,通过实验验证了模型的有效性。研究结果可为轨道交通安全状态评估和应急响应提供参考。从业人员注意事项——随着城市轨道交通规模的扩大,其承担的客流也在不断增加。频繁发生的安全事件会严重扰乱城市轨道交通的运行,造成重大的经济损失,甚至威胁到乘客的安全。如果能够提前了解城市轨道交通抵御安全事故、恢复正常运营的能力,将有助于运营管理者做出合理的判断和应急决策。为此,本文提出了一种以城市轨道交通服务水平为关键的运行弹性评价方法。

Service Level and Operational Resilience Assessment of Urban Rail Transit Under Disruption Conditions Based on Multimodal Information Perception
Urban Rail Transit (URT) system is often disturbed by various types of security incidents during operation. Therefore, effective utilization of passenger in-transit information to dynamically assess the URT system’s abilities to maintain and resume normal operation under disturbances (operational resilience) is the key and prerequisite for URT safety management and emergency response. Based on typical operational disruption scenario, this paper study the multimodal data-driven URT operational resilience and its evaluation methods. The main contributions of this research includes: capturing key information about passengers in the travel process based on historical data, and quantifying the system’s service capabilities; proposing the concept of operational resilience oriented towards URT emergency management based on service level; employing the resilience curve to analyze the evolutionary patterns of URT service levels during safety events, and emphasizing the relativity and dynamism of operational resilience; constructing a two-stage “disruption-recovery” URT operational resilience evaluation model and taking Hangzhou URT as an example to verify the effectiveness of the model through experiments. The results provide a good reference for URT safety status assessment and emergency response. Note to Practitioners—With the expansion of urban rail transit scale, the passenger flow it undertakes is also increasing. Frequent security incidents can seriously disrupt the operation of urban rail transit, causing significant economic losses and even threatening the safety of passengers. If the ability of urban rail transit to resist safety incidents and restore normal operation can be understood in advance, it will help operation managers make reasonable judgments and emergency decisions. Therefore, this paper proposed an evaluation method for operational resilience with the service level of urban rail transit as the key.
