“…Berdica believes that vulnerability is closely related to the availability of services, especially the lack of adequate service provision [6]. In recent years, literature on vulnerability has emerged in the area of critical infrastructure networks [7][8][9][10][11]. However, the resilience and vulnerability in the transportation system are not easy to measure or quantify, and recent research on vulnerability evaluation has failed to draw clear conclusions [3].…”

Abstract:In the context of the urban agglomeration and the rapid development of rail transit, the planning of the Beijing-Tianjin-Hebei Region (BTHR) rail transit 2020 is attracting attention. The BTHR is a natural disaster-prone area and a high-risk area for terrorist attacks; the robustness of the area is critical to the sustainable development of North China. Therefore, it is necessary to analyze the vulnerability of the regional planning rail transit network. This paper builds a model of planning regional rail transit in BTHR. A critical node recognition measure is designed according to the connectivity reliability of nodes. The method of Monte Carlo simulation of node connectivity reliability is applied based on link connectivity probability. In addition, a model of detecting multi-measure recognition and detecting Core-Nodes is proposed. Finally, the paper analyzes the impact of multiple attack modes on the network performance from the aspects of network performance within region and transit demand outside the region, and analyzes the vulnerability of the BTHR planning rail transit network.

“…For few studies, the authors do not reveal which kind of targeted attack they use: "We have simulated an attack on every network in our database by blocking travel through targeted stations" [83]. There are only a few notable exceptions, which correctly use interactive betweenness as a reference for network disruption simulation, e.g., [84][85][86][87]. Papers published in transportation journals rarely consider advanced network dismantling methods, emerging throughout the last 2-3 years.…”

The introduction of complex network concepts in the study of transportation systems has supposed a paradigm shift and has allowed understanding different transport phenomena as the emergent result of the interactions between the elements composing them. In spite of several notable achievements, lurking pitfalls are undermining our understanding of the topological characteristics of transportation systems. In this study, we analyse four of the most common ones, specifically related to the assessment of the scale-freeness of networks, the interpretation and comparison of topological metrics, the definition of a node ranking, and the analysis of the resilience against random failures and targeted attacks. For each topic we present the problem from both a theoretical and operational perspective, for then reviewing how it has been tackled in the literature and finally proposing a set of solutions. We further use six real-world transportation networks as case studies and discuss the implications of these four pitfalls in their analysis. We present some future lines of work that are stemming from these pitfalls and that will allow a deeper understanding of transportation systems from a complex network perspective.

“…Nationwide transport networks were also characterized using concepts of graph theory in studies such as Erath et al (2009), for rail and road transport, and Blumenfeld-Lieberthal (2009), for rail and air transport. Other studies have focused on the relations between the spatial structure of networks and their vulnerability and resilience under critical situations (Cats and Jenelius 2014;Jonkeren et al 2014;Modica and Reggiani 2014). Ducruet and Beauguitte (2013) provides a review on how the spatial approach to network analysis has evolved and integrated multidisciplinary players such as geographers, sociologists, and physicists.…”

This study focuses on the relationship between the operational performance of metro systems and their socioeconomic contexts. We use a two-stage methodology applied to a sample of 17 European metro systems. First, we apply a stochastic frontier approach to establish the optimal production function and to evaluate the efficiency and effectiveness levels of each firm through offer and demand-characterizing indicators, respectively. Only internal production factors are included in the first stage of this analysis. In a second stage, we use a similar modeling approach, but considering an additional set of variables characterizing the socioeconomic environment of the urban areas in which metro systems operate. This method allows observing the effects on operational performance measurements due to the inclusion of external factors, and consequently, drawing some conclusions on the technical efficiency of metro systems and their operations in beneficial or adverse surrounding environments. Different scores resulting from both perspectives evidence the contributions of the socioeconomic factors to improve the reliability of performance measurements and to reduce false inefficiencies. The results show that 12 of the analyzed systems are being affected by an unfavourable socioeconomic environment and/or their network suffers from some adequacy problems with regard to demand. The remaining 5 systems should improve their management strategies, since their results are being supported by a favourable surrounding environment.
