This book was released on 2015 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pedestrian safety at rail level crossings (RLXs) is a concern for government, the transport industry and the community. Collisions between trains and pedestrians are traditionally viewed as the result of errors or violations committed by pedestrians. However, as RLXs are complex sociotechnical systems, collisions are better understood as emergent properties of interactions amongst and between human and technical components within the system. Cognitive work analysis (CWA) is a powerful analytical framework that offers a sophisticated understanding of the functioning of RLXs as relevant to pedestrian safety, through identifying the constraints on pedestrian behaviour in this context. It does not, however, provide its users with guidance about how the findings of the analysis can be used to improve sociotechnical system functioning.Accordingly, the aim of this research was the development and evaluation of a CWA-based approach to support the design of complex sociotechnical systems, and the application of this approach to provide recommendations for RLX design to improve pedestrian safety. A secondary aim of the research was to investigate pedestrian behaviour within the RLX system using CWA. Drawing on systems theory, and more specifically, sociotechnical systems theory, the outcome of this research is a CWA design toolkit (the CWA-DT).The development and refinement of the CWA-DT is illustrated through a proof of concept application in the domain of public transport ticketing. Positive evaluation results were obtained and necessary refinements to the toolkit were implemented in the second version. A full evaluation of the toolkit was then undertaken within the complex, safety critical domain of RLXs. This evaluation found that while the CWA-DT could be considered a useful method, its application did not lead to the creation of design concepts that fully aligned with sociotechnical systems theory. The application did, however, lead to designs that were rated by human factors experts as more effective than the existing system design. These findings suggest that the sociotechnical systems theory approach may not provide an appropriate design philosophy in a public safety context. However, merging ideas and concepts from sociotechnical systems theory with existing paradigms such as safety management can lead to innovation and has the potential to improve safety performance.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, Cognitive Work Analysis (CWA) has been one of the popular human factors approaches for complex systems evaluation and design applications. This is reflected by a diverse range of applications across safety critical domains. The book brings together a series of CWA applications and discussions from world-leading human factors researchers and practitioners. It begins with an overview of the CWA framework, including its theoretical underpinnings, the methodological approaches involved (including practical guidance on each phase), and previous applications of the framework. The core of the book is a series of CWA applications, undertaken in a wide range of safety critical domains for a range of purposes. These serve to demonstrate the contribution that CWA can make to real-world projects and provide readers with inspiration for how such analyses can be practically carried out. Following this, a series of applications in which new approaches or adaptations have been added to the framework are presented. These show how practical applications feedback into the theories/approaches underpinning CWA. The closing chapter then speculates on future applications of the framework and on a series of new research directions required in order to enhance its utility. In emphasising the practical realities of performing CWA, and the real-world impacts it can provide, the book tackles several common misconceptions in a constructive and persuasive way. It provides a welcome demonstration of how CWA can be a powerful ally in tackling complexity-related problems that afflict systems in all areas.

This book was released on 2017-07-26 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Governments and road safety agencies around the world have either introduced or are considering 'safe system' strategies, a long overdue acknowledgement that different elements of the road system contribute to road safety outcomes. Human factors approaches have a leading role here in both conceptualising the road system as a complex sociotechnical system and in providing practical approaches to support true systems-based countermeasures. This book illustrates the potential for integrating contemporary systems-based human factors methods with modern day driving-assessment methods, such as vehicle instrumentation and driving simulation, to understand and enhance performance in modern day road-transport systems. The book outlines why a fundamental paradigm shift is needed in the way these systems are designed and operated, and illustrates how a wide range of accepted human-factors approaches can be applied successfully to road transport to revolutionise the countermeasure design process. The practical illustrations of these human factors methods are applied to a long-standing road and rail safety issue: rail level crossings, where the road and rail systems intersect. The final chapter of the book highlights the utility of the human factors approach to reducing road trauma and discusses future applications of the approach.

Download or read book The Economics of Railroad Safety written by Ian Savage and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The American public has a fascination with railroad wrecks that goes back a long way. One hundred years ago, staged railroad accidents were popular events. At the Iowa State fair in 1896, 89,000 people paid $20 each, at current prices, to see two trains, throttles wide open, collide with each other. "Head-on Joe" Connolly made a business out of "cornfield meets" holding seventy-three events in thirty-six years. Picture books of train wrecks do good business presumably because a train wreck can guarantee a spectacular destruction of property without the messy loss of life associated with aircraft accidents. A "train wreck" has also entered the popular vocabulary in a most unusual way. When political manoeuvering leads to failure to pass the federal budget, and a shutdown is likely of government services, this is widely called a "train wreck. " In business and team sports, bumbling and lack of coordination leading to a spectacular and public failure to perform is also called "causing a train wreck. " A person or organization who is disorganized may be labelled a "train wreck. " It is therefore not surprising that the public perception of the safety of railroads centers on images of twisted metal and burning tank cars, and a general feeling that these events occur quite often. After a series of railroad accidents, such as occurred in the winter of 1996 or the summer of 1997, there are inevitable calls that government "should do something.

Available in PDF, EPUB and Kindle. Book excerpt: A new approach to safety, based on systems thinking, that is more effective, less costly, and easier to use than current techniques. Engineering has experienced a technological revolution, but the basic engineering techniques applied in safety and reliability engineering, created in a simpler, analog world, have changed very little over the years. In this groundbreaking book, Nancy Leveson proposes a new approach to safety—more suited to today's complex, sociotechnical, software-intensive world—based on modern systems thinking and systems theory. Revisiting and updating ideas pioneered by 1950s aerospace engineers in their System Safety concept, and testing her new model extensively on real-world examples, Leveson has created a new approach to safety that is more effective, less expensive, and easier to use than current techniques. Arguing that traditional models of causality are inadequate, Leveson presents a new, extended model of causation (Systems-Theoretic Accident Model and Processes, or STAMP), then shows how the new model can be used to create techniques for system safety engineering, including accident analysis, hazard analysis, system design, safety in operations, and management of safety-critical systems. She applies the new techniques to real-world events including the friendly-fire loss of a U.S. Blackhawk helicopter in the first Gulf War; the Vioxx recall; the U.S. Navy SUBSAFE program; and the bacterial contamination of a public water supply in a Canadian town. Leveson's approach is relevant even beyond safety engineering, offering techniques for “reengineering” any large sociotechnical system to improve safety and manage risk.
