Abstract
Low-altitude transportation offers innovative solutions to alleviate urban congestion while reshaping urban transportation structures. This shift is likely to impact the resilience of urban multi-modal transportation (UMT) networks, requiring new methods for effective assessment. This paper develops a constrained clustering model with neighborhood search, considering points of interest (POI) distribution, passenger flow and flight distance limit, to determine potential vertiport locations. Based on location selection results and existing public transportation structure, a multi-modal transportation network is constructed. Subsequently, percolation theory is employed to assess the UMT network resilience across various cascading failure scenarios. The results indicate that the integration of urban air mobility (UAM) can significantly enhance network connectivity by providing alternative pathways during emergencies. The findings of this study highlight the potential of UAM to strengthen UMT resilience, offering valuable insights for urban transportation design and management.
期刊介绍:
Transportation Research: Part A contains papers of general interest in all passenger and freight transportation modes: policy analysis, formulation and evaluation; planning; interaction with the political, socioeconomic and physical environment; design, management and evaluation of transportation systems. Topics are approached from any discipline or perspective: economics, engineering, sociology, psychology, etc. Case studies, survey and expository papers are included, as are articles which contribute to unification of the field, or to an understanding of the comparative aspects of different systems. Papers which assess the scope for technological innovation within a social or political framework are also published. The journal is international, and places equal emphasis on the problems of industrialized and non-industrialized regions.
Part A''s aims and scope are complementary to Transportation Research Part B: Methodological, Part C: Emerging Technologies and Part D: Transport and Environment. Part E: Logistics and Transportation Review. Part F: Traffic Psychology and Behaviour. The complete set forms the most cohesive and comprehensive reference of current research in transportation science.
