Article
The systems thinking tenets were developed based on a synthesis of contemporary accident causation theory, models and approaches and encapsulate 15 features of complex systems that interact to create both safety and adverse events. Whilst initial testing provided supportive evidence, the tenets have not yet been subject to formal validation. This a...

There is growing interest in the use of systems-based risk assessment (RA) methods in human factors and ergonomics (HFE). Despite this, there has been a lack of formal reliability and validity testing undertaken to determine whether systems-based RA methods have the capacity to reliably and accurately identify potential risks within complex systems...
Article
Full-text available
Collisions between trains and road vehicles at rail level crossings remain an intractable transport safety issue. This paper describes the application of Rasmussen’s ecological interface design (EID) principles to the development of a novel ‘passive’ rail level crossing prototype design and its evaluation using two driving simulator studies. Study...
Article
There is increasing interest in applying systems Human Factors and Ergonomics (HFE) methods in sport. Risk assessment (RA) methods can be used identify risks which may impact the performance of individual athletes, teams, and overall sports systems; however, they have not yet been tested in sport. This study sets out to apply and compare three syst...

The quest to explain and understand the cause of accidents is both ever-present and ongoing amongst the safety science community. In an attempt to advance the theory and science of accident causation, researchers have recently formalised a set of ‘15 systems thinking tenets’ that cover the conditions and characteristics of work systems that are bel...
Article
There is increasing interest in applying systems Human Factors and Ergonomics (HFE) methods in sport. The Networked Hazard Analysis and Risk Management System (Net-HARMS) is a recently developed risk assessment (RA) approach that draws on systems HFE methods to identify risks across overall work systems. What makes Net-HARMS unique is its capacity...
Article
Accidents continue to create an unacceptable personal, social, and economic burden in many domains. Various accident analysis methods exist; however, key limitations have been identified. This paper describes a new accident analysis method, the Accident Network (AcciNet), that was recently developed as part of an ongoing collaboration between Human...
Article
The changing nature of work and society, and a proliferation of complex global challenges, is increasing the need for systems Human Factors and Ergonomics (HFE). The discipline is well equipped to respond, but there remain a number of longstanding issues preventing systems HFE from realizing its full impact. There is a research–practice gap, a lack...

Objective This paper presents the Binary-Based Model (BBM), a new approach to Human Factors (HF) method selection. The BBM helps practitioners select the most appropriate HF methodology in relation to the complexity within the target system. Background There are over 200 HF methods available to the practitioner and little guidance to help choose b...
Article
Crashes at intersections represent an important road safety problem. Interactions between different road user types, such as between vehicles and vulnerable road users, are a particular concern. It has been suggested driver-centric road design plays a role in crashes. A multi-road user evaluation of three novel intersection designs is described. Th...
