The integrated aviation and High-Speed Railway(HSR)transportation system plays a vital role for today's inter-city transportation services.However,an increasing number of unex-pected disruptions(such as operation failures,natural disasters,or intentional attacks)pose a con-siderable threat to the normal operation of the system,especially on ground transfer,leading to the extensive research on its vulnerability.Previous approaches mainly focus on interruptions within a single transportation mode,neglecting the role of ground transfer which serves as a coupled connec-tion between aviation and High-Speed Railway.This paper proposes a network-based framework for evaluating the vulnerability of the Chinese Coupled Aviation and High-Speed Railway(CAHSR)network from the viewpoint of ground transfer interruption.Taking the end-to-end tra-vel time and passenger flow information into consideration as an evaluation measure and analyzing from the perspective of urban agglomerations,an adaptive method is developed to identify the crit-ical cities and further investigate their failure impacts on the geographic distribution of vulnerabil-ity.In addition,the proposed model explores variations of vulnerability under different failure time intervals.Based on the empirical study,some major conclusions are highlighted as follows:(A)Only a few cities show significant impacts on the network's vulnerability when ground transfer interrup-tions occurred.(B)The distribution of vulnerability is not proportional to the distance between fail-ure city and influenced city.(C)The vulnerability is more serious in the morning and evening when the ground transfer is disconnected.Our findings may provide new insights for maintenance and optimization of the CAHSR network and other real-world transportation networks.
