Abstract

As the scale of urban rail transit (URT) networks expands, the study of URT resilience is essential for safe and efficient operations. This paper presents a comprehensive review of URT resilience and highlights potential trends and directions for future research. First, URT resilience is defined by three primary abilities: absorption, resistance, and recovery, and four properties: robustness, vulnerability, rapidity, and redundancy. Then, the metrics and assessment approaches for URT resilience were summarized. The metrics are divided into three categories: topology-based, characteristic-based, and performance-based, and the assessment methods are divided into four categories: topological, simulation, optimization, and data-driven. Comparisons of various metrics and assessment approaches revealed that the current research trend in URT resilience is increasingly favoring the integration of traditional methods, such as conventional complex network analysis and operations optimization theory, with new techniques like big data and intelligent computing technology, to accurately assess URT resilience. Finally, five potential trends and directions for future research were identified: analyzing resilience based on multisource data, optimizing train diagram in multiple scenarios, accurate response to passenger demand through new technologies, coupling and optimizing passenger and traffic flows, and optimal line design.
了解城市轨道交通的复原力:概念、评论和趋势
随着城市轨道交通(URT)网络规模的扩大,对城市轨道交通复原力的研究对于安全高效的运营至关重要。本文全面回顾了城市轨道交通的抗灾能力,并强调了未来研究的潜在趋势和方向。首先,城市轨道交通的复原力由三种主要能力(吸收、抵抗和恢复)和四种特性(稳健性、脆弱性、快速性和冗余性)定义。然后,总结了 URT 复原力的衡量标准和评估方法。指标分为三类:基于拓扑、基于特征和基于性能;评估方法分为四类:拓扑、模拟、优化和数据驱动。通过对各种指标和评估方法的比较发现,当前城市轨道交通弹性的研究趋势越来越倾向于将传统的复杂网络分析、运筹优化理论等传统方法与大数据、智能计算技术等新技术相结合,以准确评估城市轨道交通的弹性。最后,确定了未来研究的五大潜在趋势和方向:基于多源数据的弹性分析、多场景下的列车图优化、通过新技术准确响应乘客需求、客流与车流的耦合与优化、优化线路设计。
