Item The major challenges facing slovak road and railways infrastructure: current conditions, administration and priorities(University of Žilina, 2025) Miške, Michal; Figuli, LuciaThe aim of the paper is to assess the current condition of bridges in Slovakia with an emphasis on two key determinants: the ownership and administration of structures and their structural health condition. The study combines official data from the Road Database of the Slovak Road Administration (SSC), available information from the Slovak Railways (ŽSR), findings of the Supreme Audit Office of the Slovak Republic (NKÚ SR), and analytical outputs of the Value for Money Division (UHP). The paper presents an analysis of data related to ownership, administration, categories of current health condition, and accompanying documentation, providing a transparent overview of where the highest risks are concentrated. These infrastructures were identified for the purposes of the REMAKE 3D project. As part of this project, several activities were undertaken to collect information and data; however, such information is often inaccessible or does not exist. The paper includes details about bridge ownership based on a comparison of owner databases, a BIM model of bridge M7441, and an example of image processing for defect detection. The conclusion and discussion section outlines proposals for future research.Item Využitie nových technológií pri monitorovaní kritickej infraštruktúry(University of Žilina, 2023) Miške, Michal; Figuli, Lucia; Dvořák, ZdeněkIn an era marked by rapid technological advancements, the assessment of critical infrastructure resilience has also entered a new age. The incorporation of cutting-edge technologies into the evaluation process has revolutionized how we gauge the capacity of critical structures to withstand and recover from various threats, including natural disasters, cyberattacks, and other unforeseen disruptions. This transformation is of paramount importance, given the essential role that critical infrastructure plays in supporting modern societies. These technologies enable a multifaceted approach to resilience assessment, providing a more comprehensive and accurate understanding of vulnerabilities and potential points of failure. One of the primary advantages of these technologies is their ability to process vast amounts of data in real-time. Furthermore, simulations and modelling, powered by these technologies, offer a virtual testing ground for assessing resilience. Engineers and planners can simulate various crisis scenarios, evaluating the infrastructure's ability to withstand and recover from extreme conditions. This virtual experimentation enables the development of more effective contingency plans and investment strategies to enhance resilience. These tools empower decision-makers to make informed choices, reduce vulnerabilities, and improve the resilience of critical infrastructure.
