Safety: A system state or property?

Safety is frequently addressed as an emergent property of complex and dynamic systems. This contribution advocates the validity and importance of incorporating intrinsic technological hazards and systemic interrelations from a multi-actor perspective in the early phases of design and development. This perspective creates inherent properties in...

Modelling Risk Control Measures in Railways: Analysing how designers and operators organise safe rail traffic

Safe, high-quality and more frequent rail services are desired by both society and passengers. Since large scale infrastructure extensions to accommodate higher train frequencies are hardly practicable, a more intense network utilisation is considered the way to achieve these aims. As a result, trains will get in each other’s way more frequently...
