With the growing influence of climate change, the intensity of flood disasters has significantly increased throughout the world over the past decades. Among the various types of hazards caused by floods, disruption of the road network has a particularly severe impact on the mobility of emergency responders, and therefore, poses a difficult challenge to damage mitigation, especially in the urban environment. The aim of this article is to present a mapping model for analyzing the spatial pattern of flood impact on urban mobility. Specifically, by incorporating the theory of space syntax, this model focuses on two dimensions of the analysis: the performance of the road network and the relationship between the factors behind it. The former can demonstrate the extent to which the city is affected by flooding in terms of mobility, whereas the latter can provide valuable reference for enhancing the efficiency of evacuation and rescue operations.

绘制灾害图：洪水对城市交通影响的可视化分析


随着气候变化影响的日益加大，过去几十年来世界各地洪涝灾害的严重程度显着增加。在洪水造成的各种灾害中，道路网络的破坏对应急响应人员的流动性影响尤为严重，因此，对减轻损失提出了艰巨的挑战，特别是在城市环境中。本文的目的是提出一个绘图模型，用于分析洪水对城市交通影响的空间模式。具体来说，该模型结合空间句法理论，重点分析两个维度：路网的性能及其背后因素之间的关系。前者可以从流动性方面展示城市受洪水影响的程度，而后者可以为提高疏散救援效率提供有价值的参考。
