Understanding the visual skills and strategies of train drivers in the urban rail environment

Abstract

BACKGROUND: Due to the growth of information in the urban rail environment, there is a need to better understand the ergonomics profile underpinning the visual behaviours in train drivers. OBJECTIVE: The aim of this study was to examine the tasks and activities of urban/metropolitan passenger train drivers in order to better understand the nature of the visual demands in their task activities. METHODS: Data were collected from 34 passenger train drivers in four different Australian states. The research approach used a novel participative ergonomics methodology that fused interviews and observations with generative tools. Data analysis was conducted thematically. RESULTS: Results suggested participants did not so much drive their trains, as manage the intensity of visually demanding work held in their environment. The density of this information and the opacity of the task, invoked an ergonomics profile more closely aligned with diagnostic and error detection than actual train regulation. CONCLUSIONS: The paper discusses the relative proportion of strategies corresponding with specific tasks, the visualperceptual load in substantive activities, and the requisite visual skills behoving navigation in the urban rail environment. These findings provide the basis for developing measures of complexity to further specify the visual demands in passenger train driving.

Flying Off the Handle: Affective Influences on Decision Making and Action Tendencies in Real-World Aircraft Maintenance Engineering Scenarios

“…Semi-structured interviews were used to elicit knowledge and support the application of a NDM method called the Scenario Invention Task Technique (SITT) (Naweed & Balakrishnan, 2014; Naweed, Rainbird, & Dance, 2015); a generative simulation task, the SITT combined principles of multi-pass retrospective inquiry from the Critical Decision Method (Klein, Calderwood, & Macgregor, 1989) and story-telling in the Rich Picture Data method (Checkland, 1980; Monk & Howard, 1998) to externalize decision making in complex work. In this way, the SITT used retrospective and real-world experiences to effectively inform and ground prospective real-world situations.…”

“…The SITT and similar processes have been successfully applied in the context of NDM in a number of settings such as rail (Naweed & Balakrishnan, 2014) and health care (O’Keeffe, Tuckey, & Naweed, 2015) where people engage in complex and dynamic cognitive work. The process involves participants creating challenging scenarios and/or stories specific to their work with the aid of illustrations, schematic drawings, representations, and/or work plans to assist with articulation.…”

Investigation into Effects of System Design on Metro Drivers’ Safety-Related Performance: An Eye-Tracking Study

“…The in-field eye-tracking experiment was designed as a naturalistic driving study. It measured the relative cognitive impact of certain system design elements, an area which has been identified as requiring in-depth exploration [13]. The eye-tracking experiment provides a quantitative objective portrait of behaviour, whilst the interpretation of the findings is subjective in nature, using experimental observations and semi-structured interviews to generate conclusions.…”

“…The professional world is in constant evolution and, inevitably, the field of education must remain up-to-date by attempting to prepare students for a hyper-specialised and technology-driven world. Numerous transversal skills are necessary to thrive in an ever-changing professional environment (Pang et al, 2019)-both personal and interpersonal or emotional skills (Srivastava, 2013), as well as other more specific skills like visual expertise, are indispensable for certain professions (Jasani & Saks, 2013;Kok et al, 2017); Naweed & Balakrishnan, 2014;O'Halloran & Deale, 2006).…”
