# Evaluation of Urban Transportation Resilience under Extreme Weather Events
## 6 Conclusions and Future Work  
The performance indicator and index calculation method introduced in this study could accurately monitor transportation performance and capture the perturbation of the transportation network during a rainstorm. Transportation resilience under various rainstorms in different subareas of Fuzhou, China, is also quantified based on the proposed methodology in this study. The results of the case study validate the effectiveness of the proposed indicator and method, and also present the various degrees of impact from a rainstorm in the Cangshan, Gulou, and Jinan subareas of Fuzhou. The impact of a rainstorm on transportation can be mitigated by developing emergency management plans and prioritizing measures for lower resilience subareas. The approaches and findings in this study could increase our understanding about the complexity of transportation resilience and provide support for developing resilient and sustainable transportation. Additionally, this study provides valuable information for urban transportation when faced with EWEs. Based on the transportation resilience results obtained in this study, transportation managers can develop emergency plans to mobilize humans and distribute the limited material resources during the life cycle of EWEs, for the purpose of enhancing transportation resilience in different subareas of the city and guaranteeing its sustainable development. Guided by this, government departments can strengthen disaster prevention and mitigation measures, formulate emergency management policies, and pave the way for more informed and effective measures and policies, to improve the urban transportation resilience to withstand EWE-induced impacts in the future. There are several limitations in this study that need to be noted. The transportation performance and resilience calculations are only analyzed under rainstorm events in the Case Study Section. Future studies will include other EWEs, such as hurricanes [47; 48] and tsunamis [49], that can cause more severe damage to urban transportation. In addition, this study uses the baseline method to evaluate the transportation performance of the city. In future studies, the results obtained from the baseline method will be used as a reference, and new methods for evaluating urban transportation performance under EWEs will be developed. The method will be applied to multiple cities to make a comparison at various scales under different EWEs. Finally, future research will also be combined with the resilience response in the three subareas, where some concrete measures are provided for disaster resilience through interviews with disaster prevention and mitigation experts in Fuzhou.
