“…Both presented methodologies have their pros and cons, which are consistently derived from this text. Despite different calculation methods, both methodologies have the same results (i.e., numerical versus percentage), declaring degree of occupancy according to (2), respectively the occupancy time rate according to (6), as well as the use of the permeable performance according to (3), (4) or capacity consumption according to (5).…”

This contribution in a cross section way focused on the analytical determination of practical capacity of main tracks and the issue of the required capacity in the context of the comparison of national methodology used by the ŽSR and the recommended international UIC methodology. Methodology for the calculation of permeable performance within the national conditions is stipulated by ŽSR´s regulation-D24, the methodology within the international conditions for members of the UIC railway union is recommended by UIC Code 406. Both of presented methodologies have their pros and cons, which are consistently derived from this text.

“…Based on network topology-based methods, the value of network distribution p k is the probability that a randomly vertex is chosen in a node with network degree k [48]. e resilience of network can be analyzed by different network topology-based methods, including the networks epidemic disease model [49], the breakdown of network under attacks [50], the networks boundaries [51,52], and the cascading failures in network of networks [53]. In order to analyze the performance response of transport infrastructure networks under different hazards, scholars usually use the network simulation-based methods [18,54].…”

Resilience is an important property of transport infrastructure networks. Resilient transport infrastructure networks can retain the performance in case of disturbances and quickly recover to the original performance level after the disturbances. This study proposes a new approach that can measure the resilience of transport infrastructure networks. The new approach gives a unified conceptual framework for measuring the resilience of transport infrastructure networks. A network simulation-based method is used to analyze the influential factors of transport infrastructure network resilience. A new measuring method is developed based on network diversity characteristic to quantitatively measure the system resilience and node resilience of transport infrastructure networks. China railway and air transport networks are selected as a case study to applicability of new approach. This new approach provides strong supports for academic and industrial fields to measure, analyze, enhance, and optimize the resilience of transport infrastructure networks.
