“…The aim was to indicate the consequences of an inappropriate ergonomic design (with an emphasis on an inadequate design of work equipment and its HMI) and to show that ergonomic characteristics of the desk have to be adjusted to the anthropometric and biomechanical parameters of the operator. It should be mentioned that this study is only a part of larger research (Grozdanovic & Bijelic, 2019; Grozdanovic & Janackovic, 2016; Grozdanovic, Janackovic, & Stojiljkovic, 2016), which is conducted within the electric power industry, railway traffic industry, and mining industry in Serbia.…”

The subject of this paper is the interaction between an operator and the control desk at the Railway Traffic Control Room (RTCR) in Nis, Serbia. The following methods were used for this research: operators' anthropometric measurement;determining of maximum force of the movements of operators' arms; an analysis of workload of the movements of operators' arms, heads and torsos, and an analysis of errors in operators' movements in response to visual cues. The paper presents the following results: static parameter of 20 anthropometric measures of 41 operators' bodies were measured; nine corresponding dimensions of particular body parts for 5th, 50th, and 95th percentile were calculated; 10 characteristic work angles were measured; five corresponding functional body parts were calculated; times and distances covered by operators' arms were measured; maximum forces used for these movements were calculated; positions and number of movements of arms, heads, and torsos of operators were determined, and movement errors and probability of movement errors in choice of direction, arms and cumulative conditional probability were calculated.The research was conducted with the aim of discovering determining factors of mutual synchronization of the operator and desk.

“…Basic research method used for cognitive analysis is task analysis, that consists of systematic observation and registering operator’s activities in relation to the RTCR’s elements (observation of activities can include analysis of operator’s viewing angles, movements and postures of operator, interaction with RTCR’s elements; Grozdanovic & Janackovic, ); determining the consequences of operator’s cognitive activities and processes; formulations of operator’s cognitive strategies; supervision activities; control and management activities and decision making in an abnormal situation (Stojiljkovic, Grozdanovic, & Cenic, ). Informational compliance is one of main goals for adequate design of RTCR’s elements and tasks for achieving this compliance are following: Procedural task which include monitoring of predefined sequence of events; sensor and motor tasks, manipulation with input devices; communication tasks, establishing connections between the system’s elements, finding the right information; supervision tasks, supervision of the system with purpose of identifying changes regarding the system’s status; error detection, diagnosing the problem by identification of abnormal or unexpected states of the system; decision making, choosing between alternative option (Grozdanovic et al, ).…”

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.

The huge potential o®ered by the implementation of a modern Train Control Information System (TCIS) could result in signi¯cant improvements in the railway sector in general. As a technology transfer, primarily in the European railway sector, the European Rail Tra±c Management System (ERTMS) is expected to play an important role in providing better railway performances. However, the implementation of ERTMS entails certain dilemmas and disadvantages and the decision-making regarding it can be one of the crucial challenges for each railway. Having this in mind, the aim of this work is to propose a decision-making framework to support such a critical decision process through application of Strengths, Weaknesses, Opportunities, and Threats (SWOT) and Analytic Hierarchy Process (AHP) analyses. In the proposed approach, external and internal factors that simultaneously enhance and constrain ERTMS implementation were identi¯ed and presented through the SWOT analysis, while the AHP method was applied for the evaluation of the importance of identi¯ed factors. The thorough literature review represents a basis for creating a SWOT matrix and setting of judgments for the evaluation of the SWOT factors. The results of the AHP method highlight the importance of the factors within the SWOT matrix regarding ERTMS implementation. Results of the AHP method were checked by two additional weight assessments in order to provide the appropriate approach for factor evaluation. The proposed approach also shows a relatively simple and very suitable decision-making framework for consideration of other TCISs, too.
