论文摘要
运输基础设施系统的可持续性方面主要集中于基于环境，社会和经济影响的系统绩效。相比之下，弹性方面表明了承受外部冲击的能力，即稳健性以及由于这种破坏而从功能丧失（即速度）中恢复的能力。因此，可持续性和弹性是两个关键方面，在任何民用基础设施系统的计划，设计，建筑，运营和维护阶段，应给予足够的关注。由于这两个概念对于在更长的持续时间内维持基础设施同样重要，因此非常需要他们在统一框架内的同时评估。尽管最近一直着重于解决这一难题，但对现有研究的回顾表明，缺乏可以量化可持续性和弹性指标的统一框架来同时评估系统性能。此外，单个决策或绩效指标可能会加强一个并破坏另一个决定。因此，本研究提出了一个前瞻性统一框架，可以同时分析运输基础设施系统的可持续性和弹性。在这方面，使用七个关键指标（包括发射，速度，温度，能量消耗，延迟，移动性和可访问性）来解释拟议的统一框架。这项研究还研究了基于这些指数的可持续性和弹性之间的相互依存，关系和权衡。尽管某些指数将帮助系统同时获得这两种指数，但在某些情况下它们会受到损害。最后，该研究确定了即时的研究需求以及长期的研究需求。
Sustainability aspects of transportation infrastructure systems primarily focus on system performance based on environmental, social, and economic impacts. In contrast, resilience aspects demonstrate the ability to withstand external shocks i.e. robustness as well as to recover from the loss of functionality due to such disruptions i.e. rapidity. Therefore, sustainability and resilience are two key aspects which should be given adequate attention during the planning, design, construction, operations, and maintenance phases of any civil infrastructure system. As both concepts are equally important to sustain an infrastructure for a longer duration, their concurrent assessments within a unified framework are highly desirable. While there has been a recent focus towards solving this dilemma, review of existing studies revealed the lack of such unifying frameworks that can quantify sustainability and resilience indicators to simultaneously assess system performance. Moreover, a single decision or performance indicator could reinforce one and undermine another. As such, this study proposed a forward-looking unification framework, where the sustainability and resilience of transportation infrastructure systems can be analyzed simultaneously. In this regard, the proposed unifying framework is explained using seven critical indicators including emission, speed, temperature, energy consumption, delay, mobility, and accessibility. This study also investigates the interdependencies, relationships, and tradeoffs between sustainability and resilience based on these indices. While some indices would help the system to attain both at the same time, they are compromised in some cases. Finally, the study identifies immediate research needs as well as the ones in the long-term.
