“…To conduct the analysis Figures 4-6 have been employed as a 'template' for the comparison process. In a previous study [14], it has been found that in the model, the interdependency occurs horizontally and vertically and in the subsequent sections each of them will be addressed in the context of the present case study.…”

“…In this way the systemic model has a fundamentally preventive potentiality. A full account of its features and applications are given elsewhere [14,[27][28][29][30][31][32][33][34][35][36]; in the present case study, the 'structural organization' and the 'recursive' structure of the model were employed in the analysis. Regarding the 'structural organization' (Figure 4):…”

“…Operational Interdependency Figure 8 shows the 'operational' interdependency, which are highlighted by the zig-zag lines shown in red color, '6 , '7 , '12 , '13 , '14 , '26 , and '15 . Also, it should be mentioned that the figure only shows eight out of the existing twelve metro lines; however, a complete arrangement of the operational interdependency of the metro system is given in [14]). The degree of interdependency could be 'strong' (S) or 'weak' (W); for example, the metro line-C track failure affected the operation of the metro line-A (MLAO), see the zig-zag line '6 .…”

“…On the other hand, there is a growing concern on critical infrastructure interdependency [8][9][10][11][12][13][14][15]. For example, the President's Commission on Critical Infrastructure Protection (PCCIP) report defines an infrastructure as "a network of independent, mostly privately-owned, man-made systems and processes that function collaboratively and synergistically to produce and distribute a continuous flow of essential goods and services" [8].…”

Transport Infrastructure Interdependency: Metro’s Failure Propagation in the Road Transport System in Mexico City

On Friday, 3 March 2017, at about 18:19 h, a metro track failed, prompting about 50% of Mexico City's metro line-C to a halt. The track failure occurred at a peak hour when tens of thousands of commuters were heading to their homes. Given the interdependency among the modes of transportation in the capital city, the incident caused heavy disruption; it is believed that about 45,000 commuters were affected. A systemic safety management system ('SSMS') model has been used for the analysis. The results showed that: a) the model demonstrated its potential to the analysis of the transport system interdependency; it has been found that failure propagates vertically and horizontally; b) the model highlighted that failure propagation has to do with a coordination function; c) in relation to the case study, it has been found that the actions taken by the decision-makers during the emergency were less than adequate; d) the commuters traveling patterns should be considered when designing emergency plans; and, e) more generally, there is a need for the creation of a system to manage critical infrastructure protection in the context of Mexico. It is hoped that by conducting such analyses, we may gain a better understanding of the complexity of cities.

“…Several works consider the dependence of the transportation system, e.g. railroad networks , Lee et al, 2007, Santos-Reyes et al, 2015, airports (Procyk and Dhariwal, 2010), and signalized traffic intersections (Bigger et al, 2009, Procyk and Dhariwa, 2010, Kajitani and Sagai, 2009) on electric power. On the other hand, power systems can be affected by disturbances in transportation systems.…”

Transportation system resilience has been the subject of several recent studies. To assess the resilience of a transportation network, however, it is essential to model its interactions with and reliance on other lifelines. In this work, a bi-level, mixed-integer, stochastic program is presented for quantifying the resilience of a coupled traffic-power network under a host of potential natural or anthropogenic hazard-impact scenarios. A two-layer network representation is employed that includes details of both systems.Interdependencies between the urban traffic and electric power distribution systems are captured through linking variables and logical constraints. The modeling approach was applied on a case study developed on a portion of the signalized traffic-power distribution system in southern Minneapolis. The results of the case study show the importance of explicitly considering interdependencies between critical infrastructures in transportation resilience estimation. The results also provide insights on lifeline performance from an alternative power perspective. QUANTIFYING THE RESILIENCE OF AN URBAN TRAFFIC-ELECTRICPOWER COUPLED SYSTEM
