The transportation systems are facing major challenges due to changes social environment caused by the COVID-19 pandemic. How to construct a suitable evaluation criterion system and suitable assessment method to evaluate the status of the urban transportation resilience has become a predicament nowadays. Firstly, the criteria for evaluating the current state of transportation resilience involve many aspects. New features of transportation resilience under epidemic normalization are exposed, and previous summaries focusing on resilience characteristics under natural disasters can hardly reflect the current state of urban transportation resilience comprehensively. Based on this, this paper attempts to incorporate the new criteria (Dynamicity, Synergy, Policy) into the evaluation system. Secondly, the assessment of urban transportation resilience involves numerous indicators, which make it difficult to obtain quantitative figures for the criteria. With this background, a comprehensive multi-criteria assessment model based on q-rung orthopair 2-tuple linguistic sets is constructed to evaluate the status of transportation infrastructure from perspective on the COVID-19. Then, an example of urban transportation resilience is given to demonstrate the feasibility of the proposed approach. Subsequently, sensitivity analysis about parameters and global robust sensitivity analysis are conducted, and comparative analysis of existing method is given. The results reveal that the proposed method is sensitive to global criteria weights, so it is suggested that more attention should be paid to the rationality of the weight of criteria to avoid the influence on the results when solving MCDM problems. Finally, the policy implications regarding transport infrastructure resilience and appropriate model development are given.
由于新冠疫情导致社会环境发生变化,交通系统正面临重大挑战。如何构建合适的评估标准体系和评估方法来评价城市交通韧性状况,已成为当前的一个困境。首先,评估交通韧性现状的标准涉及多个方面。常态化疫情防控下交通韧性的新特征显现出来,以往侧重于自然灾害下韧性特征的总结难以全面反映城市交通韧性的当前状态。基于此,本文尝试将新的标准(动态性、协同性、政策性)纳入评估体系。其次,城市交通韧性评估涉及众多指标,这使得标准难以获得量化数值。在此背景下,构建了基于q-阶正交对二元语言集的综合多准则评估模型,从新冠疫情的角度评估交通基础设施状况。然后,给出了一个城市交通韧性的实例,以证明所提方法的可行性。随后,进行了参数敏感性分析和全局稳健敏感性分析,并与现有方法进行了对比分析。结果表明,所提方法对全局准则权重敏感,因此建议在解决多准则决策问题时,应更加关注准则权重的合理性,以避免对结果产生影响。最后,给出了关于交通基础设施韧性和适当模型开发的政策建议。
