“…Hence, it should be noticed that a working shift should not be designed further than 8 hours. This can be attributed to the evident relationship between reaction time and neural sensors (Baldock et al , 2007; Dobres et al , 2017).…”

“…This was clearly visible in the operators’ behaviour during the experiments. It is suggested to take a short break periodically, for instance 5- to 10-min break per 60 min of continuous monitoring (Baldock et al , 2007; Fallahi et al , 2016). Hence, it should be noticed that a working shift should not be designed further than 8 hours.…”

“…The reported maximum width of sight is 120°. However, as distinguished in Baldock et al (2007), the validity of the useful field of view test in predicting operator’s performance is vague as results of various studies failed being replicated. The best distance to position the screen from the operators was reported 62.5 cm where the screen size is closed to the visual acuity limits (Rempel et al , 2007; König et al , 2014).…”

Purpose This study aims to provide an ergonomic design of the monitoring room that has resulted in safe, functional and comfortable environment for the operators, which may lead to improve the efficiency. Currently, uses of closed‐circuit televisions to monitor the critical environments are widely applicable. The information is continuously transferred and analyzed through a center called monitoring room. Design/methodology/approach Here, through creating a systematic analysis, a series of experiments was performed initially to evaluate and then optimize the parameters such as illumination, visual angle, operator-screen distance, number of scenes display in a single screen, workstation height, screen dimension and monitoring time that may affect the visual skill of the operators. Taguchi orthogonal array was used to analyze the significance of parameters on operator’s response time to a threat. The five parameters were distinguished as significant. Later response surface methodology was utilized to optimize the parameters. Findings Quadratic empirical model developed for the response time exposes the optimum response time was achievable at illumination of 500 lux, visual angle of 13°, operator-screen distance of 60 cm, three scenes, workstation height of 120 cm, screen dimension of 34” and monitoring time of 15 min. This shortened the response time by 28 per cent. The adequacy of the fitted model was successfully verified using the confirmation test with α = 95 per cent. Originality/value The novelty of this work lies in the application of a systematic statistical analysis, which enables considering the interaction among the noise parameters and controllable one simultaneously. Furthermore, the obtained regression model can widely be used for adjusting the parameters accordingly based on various anthropometric data.

“…To illustrate, shifting ability (mostly measured by trail making tasks) was found to be correlated with car crash risk 31 , road test driving behaviors 34 , hazard perceptions 37 , and driving errors in lane position 52 . Researchers also found that inhibition ability, which is related to selective attention, was associated with road test scores 53 , on-road driving performance 35 , and observation errors 52 . Updating ability, which is related to working memory 54 , plays an important role in drivers' decision making 38 .…”

“…Driving is a complex task that requires various cognitive abilities. For instance, visual attention and visuospatial cognition are related to overall driving performance 34,35 : perceptual-cognitive capacity is related to speed control and crash risk 36 , simple RT is related to hazard perception 37 , and working memory is related to decision making 38 . Adrian et al 39 concluded that functional abilities were more determinant than chronological age in predicting elderly drivers' performance.…”

The development of highly automated vehicles (HAV) can meet elderly drivers’ mobility needs; however, worse driving performance after a takeover request (TOR) is frequently found, especially regarding non-driving related tasks (NDRTs). This study aims to detect the correlation between takeover performance and underlying cognitive factors comprising a set of higher order cognitive processes including executive functions. Thirty-five young and 35 elderly participants were tested by computerized cognitive tasks and simulated driving tasks to evaluate their executive functions and takeover performance. Performance of n-back tasks, Simon tasks, and task switching were used to generate updating, inhibition, and shifting components of executive functions by principal component analysis. The performance of lane changing after TOR was measured using the standard deviation of the steering wheel angle and minimum time-to-collision (TTC). Differences between age groups and NDRT engagement were assessed by two-way mixed analysis of variance.Older participants had significantly lower executive function ability and were less stable and more conservative when engaged in NDRT. Furthermore, a significant correlation between executive function and lateral driving stability was found. These findings highlight the interaction between age-related differences in executive functions and takeover performance; thus, provide implications for designing driver screening tests or human-machine interfaces.
