At the substructure level, different motifs exhibited varied responses, with densely connected motifs experiencing reductions in their percentage distribution, while less connected motifs showed increases.

To reflect the multidimensional considerations in measuring system resilience, leading indicators from four dimensions (economic, environmental, social, and technological) are selected.

Based on the method of Macroscopic Fundamental Diagram (MFD), mathematical models are presented to characterize the time-varying evolution of both e-hailing vehicles and other vehicles within a two-region transport system, and management approaches are also provided to improve the evacuation process. Considering drivers’ repositioning decisions and passengers’ demand dynamics, a region-dependent pricing strategy is developed for rapid massive evacuation. In the numerical examples, it is observed that the region-dependent pricing strategy effectively allocates a more balanced distribution of vacant vehicle supply, despite higher generalized wage for drivers and increased generalized cost for passengers.
