Abstract
The formation mechanism of cross-city transportation network resilience occupies an important position in cross-city transportation network resilience management. This study analyzes the constituent elements of the cross-city transportation network and their interrelationships, and the connotation of cross-city transportation network resilience is defined from the general meaning of system resilience. Combining with the connotation of cross-city transportation network resilience, the specific formation process of cross-city transportation network resilience is analyzed and summarized from three stages, including resisting disturbance, absorbing disturbance, and function recovery. Taking cross-city transportation network nodes and systems as specific objects, the static and dynamic formation path of cross-city transportation network resilience is condensed. Based on the standard linear solid model, a theoretical model is constructed and solved for revealing the formation mechanism of cross-city transportation network resilience. Finally, the theoretical model of cross-city transportation network resilience proposed in this study is used for analyzing the China railway network resilience.
Highlights
With the continuous advancement of urbanization, cities and transportation infrastructure between cities form a huge cross-city transportation network in the form of nodes and links [1, 2]
Related research studies on the formation mechanism of crosscity transportation network resilience can enhance the selfrecovery ability of network nodes and links in the cross-city transportation network, which is beneficial for cities to mobilize resources from the network level during emergencies and reduce losses and quickly recover after disturbance occurring [10,11,12]. erefore, the resilience management of cross-city transportation network has gradually become a new research paradigm
In the static formation path, cross-city transportation network resilience is formed by the static resistance of city nodes to external disturbance, which reflects the nodes’ resilience of the cross-city transportation network
Summary
With the continuous advancement of urbanization, cities and transportation infrastructure between cities form a huge cross-city transportation network in the form of nodes and links [1, 2]. Existing research studies on resilience management of cross-city transportation networks have found that local disturbances faced by regional transportation network will be amplified and become common disturbances by crosscity transportation [3, 13]. Few research studies on the formation mechanism of the cross-city transportation network resilience focus on the changing of network scale and structure influencing cross-city transportation network resilience [22, 30, 31]. E connotation of cross-city transportation network resilience was not clear, and existing research studies did not establish a quantitative model for analyzing the cross-city transportation network resilience considering the network structure characteristics.
