Abstract

Faced with chronic traffic congestion and spatial inequities, global megacities urgently need urban air mobility (UAM) integration to enhance transportation resilience and promote equitable mobility. This study constructs a constrained clustering model to identify vertiport locations, considering no-fly zones and integrating passenger flow demand and point of interest (POI) distribution. By constructing a two-layer transport network and employing percolation theory, we systematically evaluate how vertiport deployment strategies impact regional-level resilience and equity. The findings of the Beijing case reveal the relationship between deployment scale and resilience equity. Moderate deployment helps to improve and compensate for regional resilience differences, balance efficiency and fairness, but large-scale deployment exacerbates inequality. This research underscores the importance of strategic and non-uniform vertiport siting to mitigate urban transport disparities, providing theoretical insights and policy recommendations for equitable UAM development.

考虑城市空中交通一体化的城市交通网络弹性公平性分析

面对长期的交通拥堵和空间不平等，全球特大城市迫切需要城市空中交通（UAM）一体化，以增强交通弹性，促进交通公平。本文在考虑禁飞区的基础上，结合客流需求和兴趣点分布，构建了一个约束聚类模型来确定垂直机场的位置。通过构建两层运输网络并运用渗透理论，我们系统地评估了垂直机场部署策略如何影响区域层面的弹性和公平性。北京案例的发现揭示了部署规模与弹性公平之间的关系。适度部署有助于改善和弥补区域弹性差异，平衡效率和公平，但大规模部署会加剧不平等。本研究强调了战略性和非统一垂直机场选址对于缓解城市交通差异的重要性，为公平的垂直机场发展提供了理论见解和政策建议。
