Full textRoad signs can be regarded as the most common means of traffic regulation and communication to road users. The driver’s ability to understand a road sign therefore is essential for traffic safety. However, a large body of research shows that – with a mean comprehension value that varies between 50 and 70% - drivers have difficulties in understanding the meaning of traffic signs. The use of pictorials represents one way of conveying simplified, standardized pieces of information. With the increase in traffic volumes over the last decades, a lot of countries have introduced such symbolic signs to facilitate international travelling where language differences constitute linguistic barriers. Currently, a variety of studies on symbolic warning and mandatory signs, but not on directory signs exists. The present study subsequently deals with the improvement of directory signs in road traffic for national and international drivers regarding comprehensibility, correctness of decisions and reaction times. The aim of this study is to contribute to existing research on the topic of use of pictorials in road traffic and on traffic safety. A reaction time experiment was developed and carried out with 101 participants aged 18 to 87. 63 of the test persons had acquired German as mother language; for 38 of the participants, German was not the native tongue. Each participant was presented with 32 German directory signs that had specially been developed for the experiment. Participants had to indicate the direction they would use to reach a certain predetermined target location that could either be represented verbally or as a symbol. Two hypotheses were tested: the first hypothesis stated that pictorials should be detected faster and more accurately than verbal targets. This could not be confirmed; instead, we found the opposite pattern. The second hypothesis assumed that German native speakers would show faster reaction times and a greater number of correct answers for symbolic as well as for verbal targets compared to non-native German speakers; this hypothesis could be confirmed. Including the covariates age, sex and driving experience, a very significant effect of age as well as of the specific sign that the subjects were presented with could be shown; the previously found main effect of target type (verbal/pictorial) was not significant, anymore. Finally, the present study discusses possible reasons and influencing factors for the observed effects like arrangement and number of targets on a sign as well as the word length of the used targets

Full textAdvanced driver assistance systems are increasingly built in vehicles with the aim to support drivers while driving, to reduce driver errors and thereby to increase traffic safety. At present, these systems are often designed to warn drivers of specific safety risks (e.g., of an imminent departure from the driving lane). However, there is a trend towards systems that more strongly intervene in driving and that hence, automate parts of the driving task (e.g., autonomously keep the vehicle within the driving lane). However, research on human-machine interaction has shown that automation does not necessarily increase safety, but that it may also lead to unanticipated side effects on performance and safety to the extent that humans adapt to the changing task demands. A major concern in road traffic is that drivers rely too heavily on driver assistance systems, become less actively involved in the driving task, and divert their attention to things unrelated to driving. Thus, in the case of system malfunctions or failures, drivers possibly may not be prepared to intervene timely and accordingly and to regain control over the vehicle, respectively. The aim of this dissertation was to investigate changes in drivers’ active engagement in the driving task as a function of the degree to which they are supported by a driver assistance system (i.e., as a function of the degree to which the system automates the driving task). Drivers’ active task engagement was studied by referring to two theoretical concepts: a) drivers’ reliance (on a system) and b) drivers’ situation awareness. Based on an extensive review of previous research on automation, a conceptual theoretical framework was developed that links changes in operators’ active task engagement to human adaptation processes on different levels in response to the changing task demands due to automation. Among them are changes in human attitudes as well as in cognitive, motivational and energetic processes. In order to determine the relative influence of these processes, a range of objective and subjective measures was collected. The essential part of the dissertation is an extensive driving simulator study in an advanced moving-base driving simulator at VTI (Swedish National Road and Transport Research Institute) in Linköping, Sweden. Two lateral support systems (a Heading Control system and a Lane Departure Warning system) were implemented which assisted drivers to different degrees in lane keeping. Contrary to most previous automation studies, drivers’ reliance on the lane keeping assistance systems and their situation awareness were studied by using process-oriented performance-based measures. Drivers’ reliance on the lane keeping assistance systems was assessed by eye glance behaviour measures indicating drivers’ preparedness to allocate their visual attention away from the road scene to an in-vehicle secondary task. Drivers’ situation awareness was assessed by behavioural measures of the latency and magnitude of drivers’ initial reactions to unexpected critical driving situations. A major finding of the study was that drivers differed significantly in their reliance on a high level of lane keeping assistance. This interindividual variance in drivers’ reliance on higher-level assistance could be best explained by drivers’ trust in the system and their energetic arousal: The greater drivers’ trust in the system and the lower their arousal, the more did they rely on the system. Individual driver variables (driving style) explained a significant proportion of the variance in drivers’ trust in the lane keeping assistance systems. (replaced because a new publisher)

Full textIn daily life, we constantly have to adjust our goals and plans to changing task demands and internal needs. Our ability to balance the initiation and inhibition of our actions, and to solve resulting conflicts between them, is referred to as cognitive control. To study the processes of cognitive control, the Stroop Paradigm has become a popular tool (Stroop,1935). The Stroop Paradigm is frequently used to address central questions of cognitive control. It is, for instance, an open issue, where and when in the processing stream cognitive conflicts arise. Do they arise early, for example, during the retrieval of target and distractor? Or do they occur late, when the response is prepared for execution? Another debate is concerned with the question whether the findings agree for different Stroop variants (Van Maanen et al., 2009). In this dissertation I present research on the temporal characteristics and the neural substrates of cognitive conflicts during the processing of objects and numbers. To better understand the locus of the conflict, the retrieval phase and the response phase are modelled separately. The results from several reaction time studies and from two fMRI experiments speak to the issue that processing costs occur during retrieval, i.e., early in the processing stream, for both, object and number representations. The results further indicate that the processing of the conflict between target and distractor for number and object representations do not rely on common neural substrates. I will thus present the results from behavioural and functional imaging experiments, showing similar temporal patterns for the conflicts in both systems, but distinct underlying neural networks.
