“…Wilms and Zeilstra 20 compared the Dutch IWS to TaskWeighing, a tool that is used to estimate the amount of workload imposed by the task demands. 21 Promising, positive correlations were found between the results obtained using TaskWeighing and the Dutch IWS, but a direct comparison between the original English IWS and the Dutch IWS was not made. Moreover, in-the-field use of the Dutch IWS in domains other than train traffic control has suggested that alternate translations of some items could be more appropriate.…”

The Integrated Workload Scale (IWS) is a scale for the assessment of subjective workload in real-time that was specifically designed for use with train traffic controllers. The IWS has nine anchor points that describe the degree of workload-ranging from 'not demanding' to 'work too demanding'-and captures the multi-dimensionality of workload by incorporating items that reflect time, demand and effort. In this paper, we describe how we translated the IWS into Dutch and subsequently validated the translation by having English-language students, Dutch students and Dutch train traffic controllers rate the individual items of the IWS according to the amount of workload each item conveyed, on a scale ranging from 0 ('no workload at all') to 150 ('complete overload'). A comparison between the ratings of the English and Dutch items showed no significant differences, suggesting that the English and Dutch versions of the IWS are perceived similarly. Moreover, a comparison between the Dutch students and train traffic controllers also showed no apparent differences in the items' ratings. Regression analyses showed a strong linear component reflecting that the items were roughly equidistant on the rating scale. In a final analysis, alternate translations were tested as possible substitutes for some of the original items, but were not considered to substantially improve the scale. In sum, the similarity of the Dutch IWS to the original IWS, as well as the fact that train traffic controllers and students gave similar ratings on the Dutch IWS, suggest that it is a robust and reliable tool for subjective workload assessment across different populations and that it can be reliably translated to other languages.

Abstract-Estimating signaler demand is critical for ensuring signaling workstations are both feasible to run, and acceptable to staff. While human factors tools exist, they are typically manual, time consuming and rely of the skill of an expert. One solution, explored in this paper, is to use signaling simulators to assist in the estimation of demand.Full fidelity signaling simulators are already widely used in the UK. Simulators give the ability to ensure a consistent standard of competency ranging from normal routine tasks to abnormal situations (e.g. faults and failures) monitored by an experienced trainer/assessor. Whilst the original aim of full fidelity simulators was to support training and assessment of signalers, the requirement for an accurate timetable and infrastructure model, and of a realistic workstation Human Machine Interface (HMI), opens up other applications.The aim of the Dynamic Modelling of Operator Demand (D-MOD) project is to use the Hitachi Information Control System's simulation environment (TREsim signaling simulator) to deliver a workstation evaluation tool. The paper will present how the existing elements of simulator have been expanded and utilized for demand modelling, covering the architecture of D-MOD, the process of selecting and developing demand metrics, and the design of an HMI to deliver a working proof of concept.
