Analysis of safe and effective next-generation rail signalling systems

Moving Block (MB) and Virtual Coupling (VC) rail signalling will change current train operation paradigm by migrating vital equipment from trackside to onboard to reduce train separation and maintenance costs. Their actual deployment is however constrained by the industry's need to identify configurations of MB and VC signalling equipment...

Achieving Organisational Alignment, Safety and Sustainable Performance in Organisations

When looking at socio-technical systems from a systems thinking and systemic perspective, it becomes clear that mental models govern the behaviours and determine the achievements of socio-technical systems. This is also the case for individuals, being systems themselves and, as such, being elements of those socio-technical systems. Individual...

Safety science, a systems thinking perspective: From events to mental models and sustainable safety

In the past one hundred years, concepts such as risk, safety and security have become ever more important and they represent a growing concern in our society. These concepts are also important subjects of study to enhance sustainability. During the past fifty years, safety science has gradually developed as an independent field of science. In...

An ontological and semantic foundation for safety and security science

When discussing the concepts of risk, safety, and security, people have an intuitive understanding of what these concepts mean, and, to a certain level, this understanding is universal. However, when delving into the real meaning of these concepts, one is likely to fall into semantic debates and ontological discussions. In industrial parks,...
