“…Zhang et al (2014) proposed a fuzzy decision analysis method for safety management in tunnel construction. Research can also be found in the operation phase (Wang et al 2007;Lu et al 2011Lu et al , 2013Deng et al 2015). Research has also focused on subsystems such as fire evacuation systems (Zhong et al 2008), ventilation systems (Li, Chow 2003), etc.…”

“…Incident case analysis (ICA) has been widely used for construction safety management (Hinze 1997), and incidents occurring in a subway lifecycle contain abundant information that has been frequently used for safety promotion (Zhou et al 2011;Zhang et al 2016). While ICA is an empirical approach that studies incidents that occurred in the past, network theory provides an useful tool to model subway physical systems as a network and learn the dependence and interdependence of its subsystems in lifecycle safety performance (Deng et al 2015). This paper combines these two methods to validate the DFS concept in subway projects and help improve the understanding of subway design work in lifecycle safety management.…”

“…Safety management in subway projects is not only about the reduction of incidents on jobsites or in service; it is also crucial to the economic development and social stability of society (Deng et al 2015). While numerous studies have been performed to promote subway safety management in the construction phase (Zou, Li 2010;Ding et al 2012;Zhou et al 2011Zhou et al , 2014 and the operation phase (Zhong et al 2008;Lu et al 2013;Deng et al 2015;Zhang et al 2016), the design phase is often ignored. According to the DFS concept, the best way to improve subway lifecycle safety performance is to have a good understanding of SPSN and design the potential hazards out of SPSN, while understanding the safety performance of each subsystem and their dependence and independence are also conducive to the implementation of DFS.…”

Abstract.Regardless of potential benefits of design for safety (DFS) concept for lifecycle safety management in construction industry, DFS adoption as an early intervention has been slower than expected. While existing research mainly concentrates on construction and operation phases, the role of design phase in construction safety management is always ignored. To validate the influence of DFS concept on lifecycle safety performance, this research conducted an incident case analysis (ICA) based on 442 cases collected from lifecycle subway projects, and a subway design-incident classification model (SDICM) was developed to help identify their relationship to DFS concept. Network theory was applied to study the interdependence of 22 subsystems obtained from China's code for metro design in lifecycle safety performance. Research findings show 236 out of 442 accidents are linked to DFS. Compared with construction phase, operation phase is more susceptible to design work. Station Building (SB), Section Construction (SC), Platform Screen Doors (PSD), Vehicle Systems (VES) and Power Supply Systems (PSS) are identified as having the highest number of accidents. The results of network analysis are consistent with ICA and demonstrate the safety interdependence of subsystems. This research can help improve the cognizance of DFS, and the identified subsystems should be given priority in the design phase.

“…Exploring the vulnerability of rail transit system has been proven to obtain significant contributions to improve systems' performance [6]. As a result, the vulnerability of rail transit system has gained extensive attention in regard to the influence of the network characteristics [7,8], the technology of the infrastructure and vehicles [9], the workers, and the passengers [10], just to mention a few. Nevertheless, what is noticeable is that almost all of these studies have been limited in that research on a portion of rail transit system.…”

Abstract:As a sustainable means of public transportation, urban rail transit system undergoes rapid expansion in China. How to provide a safe and reliable service has been the subject of growing attention in this context. However, such work is challenging because rail transit systems are quite vulnerable and influenced by a set of interacting factors. Studying these vulnerability factors will contribute significantly to the operation of rail transit system. From this perspective, this paper made an exploration of the vulnerability factors based on an integrated method consisting of AHP (Analytical Hierarchy Process) and ISM (Interpretative Structural Modeling). Based on literature review, 21 vulnerability factors were identified. Subsequently, expert elicitation was employed to ascertain the importance of each factor and the interrelations among them. The results suggest that management and individual factors have the highest importance weights and the interrelations among vulnerability factors could be expressed as a five-layer structure, in which management factors were inclined to be at the lower level. The research provides valuable information for decision makers to take proactive strategies and reinforcement policies to guarantee safety operation of urban rail transit system and ensure urban public safety, which could promote the sustainable development of cities.

This study considers the problem of protecting metros against terrorist attacks. We have collected statistics on all terrorist attacks committed in the metro since 1883, and we have analyzed the efficiency of technical security systems deployed at the metro. The analysis conducted showed that technical systems employed presently in metros cannot prevent bringing explosive devices of a certain type into the metro. Mathematical calculations make it possible to establish the assigned risk of delivering explosive devices of a certain type into metros. The research offers a possible way of increasing the level of security in the metro against the conveyance and use of explosive devices.Keywords Metro Á Subway Á Terrorist attack on metro stations Á Act of terrorism in the subway Á Statistics on all terrorist attacks in the metro
