System theory and safety models in Swedish, UK, Dutch and Australian road safety strategies

Miles away or just around the corner? Systems thinking in road safety research and practice

“…The strategies contained substantial similarities, but were different in terms of fundamental constructs and principles. While acknowledging strong and unique features of each strategy, Hughes et al (2014b) suggest that the modern strategies do not include essential aspects of systems theory that describe relationships and interdependencies between key components. Hughes et al (2014b) conclude that the description of these strategies as systems is therefore not well founded and deserves further development, initially at a conceptual level.…”

Risk management in Norwegian avalanche rescue operations: Managing uncertainty, complexity, overcommitment and the long-term monitoring of accident risk

“…In this sense, the rescue service is an operating entity "comprising discrete components which transform input to output for a purpose" (Hughes et al, 2015, p. 272). Hughes et al (2015) refer to six systems theory based criteria in their assessment of road safety strategies and their relation to systems theory, which in the context of avalanche rescue can be transformed to:…”

Contributory factors interactions model: A new systems‐based accident model

“…Models describe something to provide information in the form of a simplified representation or description to offer aid in understanding. They create a picture that facilitates questions, develops rules, investigates, analyses, identifies, and evaluates countermeasures and communication (Hughes, Anund, & Falkmer, ). The attempt to explain an accident is as old as the scientific study of the accident itself (Elvik, ).…”
