“…Ergonomics methodologies and tools are used for the analysis and optimization of cognitive and physical interactions within a control room; interviews and measurements (i.e., eye‐tracking and motion capture) allowed us to model operators’ interaction with their workstations in different scenarios (e.g., time of the day, traffic loads) and the physical and cognitive outcomes of such interaction (e.g., fragmentation of the information flow; Mastrangelo et al, ). Cognitive task analysis and workload scale are used for research of the operator’s workload (Pickup, Wilson, Nichols, & Smith, ). In addition to intellectual and physical abilities, the operator’s work in the control room requires significant visual abilities.…”

The aim of the research presented in this paper is to perform an ergonomic evaluation of compatibility between control desk, display panel, and their control devices with operators’ capabilities in the process of railway traffic control. This paper covers the application of ergonomic criteria for designing the control room and its main elements, functional characteristics of operators, and the influence of illumination on operator’s work efficiency. The paper also introduces methodologies for anthropometric and kinesiological analysis of operators, ergonomic analysis of control desk and display panel, and analysis of illumination in the Railway Traffic Control Room in Nis, Serbia. The research also includes basic statistical parameters for body measures of operators, configuration, and dimension of control desk as a unit, ergonomic analysis of control desk buttons, ergonomic analysis of display panel and its elements, parameters for illumination level of control room, control desk and display panel, and uniformity of illumination and brightness. To establish a link between these research and cognitive demands, methods of cognitive analysis of control and management activities in control room and decision making in abnormal situation by using an operator’s stress model are presented. The importance of this approach is that ergonomic assessment of current condition will determine the inadequate design and the ergonomic approach to be used in the implementation of the analysed control room. The results given in this paper enable the beginning of reconstruction and design of new elements in the control room, which will lead to abettor optimized control of railway traffic.

“…During the analysis of the DO's workload, cognitive task analysis and workload scale are used (Pickup et al, 2005;). An especially demanding task is alarm handling in the case of voice communication with the location where the emergency situation arises (Dadashi et al, 2013;Buddaraju, 2011).…”

This paper presents an analytical–synthetic model of ergonomic research of the abilities of the dispatcher/operator in the control room for the automatic control of railway transportation. Twenty performance indicators describing the operators’ performance (work capacity and perceptive abilities) and the main characteristics of the control room (work organization and ergo-technical analysis) are identified. A group fuzzy analytic hierarchy process is applied in the process of ranking and selection of key performance indicators of railway control rooms. The selected key performance indicators (the operator’s hand movement, visual symptoms of fatigue, device error analysis, location and dimensions of the control desk) are analysed in detail.
