    Driver Fatigue and Accidents: Can Visual Sensitivity Predict Drivers' Ability to Drive Safely?2000In: Ergonomics for the New Millenium: proceedings of the XIVth Triennial Congress of the International Ergonomics Association and 44th Annual Meeting of the Human Factors and Ergonomics society, July 29 through August 4, 2000, San Diego, California USA, Human Factors and Ergonomics Society, 2000, Vol. Vol. 3, p. 267-270Conference paper (Refereed)
    Abstract [en]

    The aim of the study was to investigate whether visual sensitivity, defined as the ability to quickly detect and react to a visual stimulus, could be used to predict drivers' ability to drive safely. Ten sleep-deprived and ten alert subjects drove for two hours on a simulation of a motorway, in an advanced driving simulator, and were exposed to a number of critical traffic situations. The results showed that visual sensitivity could predict about 50% of the subjects' variation in lateral position. Implications for the design of a driver support system, based on measurement of visual sensitivity, are discussed.

    Lingvistisk analys av säkerhetssamtal inom Banverket2007Report (Other academic)
    Abstract [en]

    The purpose of this study was to investigate possible risk factors related to the quality of spoken communication between train drivers and train dispatchers at Banverket (Swedish Rail Administration). In a first stage 1422 recorded and transcribed dialogues were subject to an exploratory linguistic analysis. In a second stage 200 dialogues were sampled and made subject to a detailed analysis in terms of communication error types. Results showed an overall low frequency of communication errors. Errors actually observed were mainly related to deficiencies in identification and designation.

    Work domain analysis of driving information2009Conference paper (Refereed)
    Abstract [en]

    In order to drive in a safe and environmentally friendly manner a driver needs support on the skillbased, rule based and knowledge based level (Rasmussen, 1986). It can be argued that today's driverinformation mainly supports skill and rule based levels while the complex task of driving also needssupport on the knowledge based level, e.g. problem solving . The aim of this study was to identifyways to support problem solving and decision making in a driving information context and to studygaps, overlaps, strong and weak relations between the driver information functions and the purpose ofthe functions.Work Domain Analysis (WDA) (Vicente, 1999) was used to decompose the purpose of the driverinformation down to the component level. WDA is the first step of five in Cognitive Work Analysis(CWA). CWA belongs to the category of Ecological Interface Design that aims to aid the design ofhuman centred interfaces and systems that support problem solving and decision making in complexsocio-technical systems.The study was performed by researchers from Luleå University of Technology and Volvo Cars as wellas members of a Driving information project. The study was limited to driver information systems inprivate cars which means that the main purpose of the systems was to support drivers' goals e.g.navigate or maintain speed but also being environment friendly, etc. It should also be mentioned thatdriver information not only was limited to information within the car. Before and after driving was alsoincluded. The WDA identified five functional purposes of driving information: To support safe,efficient, environment friendly, legal and enjoyable transportation.The "Functional purpose" was decomposed into "abstract functions" e.g. support choice oftransportation, reduce energy exposure, improve friction, and maintain lateral and longitudinal distance.Further decomposition down to "physical form" showed several weak and some unexpected relationsbetween the purpose and the system. For instance, one conclusion was that the relation betweenspeedometer and safety was weak. The weak relations and the gaps then served as input for designimplications.In the design implications part it was concluded that planning could be improved in comparison withtoday's systems by e.g. internet services and pre- and post-trip information. New features in thenavigation system, such as route optimization based on safety or carbon footprint, could improve bothsafety and environmental friendliness. Feedback or Edutainment (Education by Entertainment) couldalso serve as a way to improve safety and green driving. A rather controversial and perhaps unrealisticsuggestion is that a private car could provide statistics or data about safety, environmental friendlinessor efficiency (Cost) for different types of transportation in order to make the choice of transportationoptimized.Another, more general conclusion is that the decomposition also showed the importance for a designerto ask the question "why?" when designing a product.

    Auditory signs to support traffic awareness2009In: 16th World Congress and Exhibition on Intelligent Transport Systems 2009: 16th ITS World Congress ; Stockholm, Sweden, 21 - 25 September 2009, Red Hook: Curran Associates, Inc., 2009Conference paper (Refereed)
    Abstract [en]

    Informative systems might contribute to sensory and cognitive driver distraction, which in turn can lead to a more dangerous driving behavior. In this study we evaluated auditory signs to support drivers traffic awareness during simulated driving. 18 truck drivers identified traffic situations based on information conveyed by brief sounds. Aspects of learning, interpretation and pleasantness of sounds were monitored and rated by the drivers. Sounds which were arbitrary mapped to traffic situations required longer learning times, resulted in degraded choice reaction performance, and were rated as less pleasant compared to sounds with a high level in context specific meaning.

    Neuropsychological aspects on driving after brain lesion: simulator study and on-road driving1997In: Applied neuropsychology, ISSN 0908-4282, E-ISSN 1532-4826, Vol. 4, no 4, p. 220-230Article in journal (Refereed)
    Abstract [en]

    29 patients with brain lesion and 29 matched controls completed a neuropsychological test battery to assess perceptual, cognitive, and executive functioning and were tested on driving performance in a simulator and actual road conditions. The patients were socially well recovered with a high rate of employment. Patients performed significantly worse than controls on the test battery, especially on executive and cognitive functions. Patients drove as well as controls in predictable situations in the advanced simulator used In unpredictable situations, patients demonstrated longer reaction time (RT) and safety margins, as well as difficulties in allocating processing resources to a secondary task. Patients showed significantly less attention, worse traffic behavior, and less risk awareness when driving in real traffic. 41% of the patients did not pass the driving test. The neuropsychological test battery was factor analyzed into 4 factors: executive capacity, cognitive capacity, automatic attentional capacity, and simple perceptual-motor capacity. The second factor was the most significant, with a simultaneous capacity test predicting driving performance with 78% confidence. (PsycINFO Database Record (c) 2007 APA, all rights reserved)

    Changes in driver behaviour as a function of handsfree mobile phones: a simulator study1991In: Proceedings of the Conference Strategic Highway Research Program and Traffic Safety on Two Continents: in Gothenburg, Sweden, September 18-20, 1991, Linköping: Statens väg- och transportforskningsinstitut, VTI , 1991, p. 27-44Conference paper (Refereed)
    Abstract [en]

    The effects of a mobile telephone conversation on drivers' reaction time, lane position, speed level, and workload in two driving conditions (easy versus hard driving task) were studied in an advanced driving simulator. Forty subjects, experienced drivers in the ages 23-61 years, were randomly assigned to four experimental conditions. It was found that a mobile telephone conversation had a negative effect on drivers reaction time, when the driving task was easy. It led to a reduction in speed, when the driving task was easy. It had a negative effect on drivers' lane position, most pronounced when the tracking component of the driving task was difficult. Finally, it led to an increase in workload for both the easy and hard driving task. The effects were discussed in terms of what subtask, car driving or telephone conversation, the drivers gave the highest priority. Some implications for information systems in future cars are discussed.

    Changes in driver behaviour as a function of handsfree mobile telephones: a simulator study1994In: Accident Analysis and Prevention, ISSN 0001-4575, E-ISSN 1879-2057, Vol. 26, no 4, p. 441-451Article in journal (Refereed)
    Abstract [en]

    The effects of a mobile telephone task on drivers' reaction time, lane position, speed level, and workload were studied in two driving conditions (an easy or rather straight versus a hard or very curvy route). It was predicted that the mobile telephone task would have a negative effect on drivers' reaction time, lane position, and workload and lead to a reduction of speed. It was also predicted that the effects would be stronger for the hard driving task. The study was conducted in the VTI driving simulator. A total of 40 subjects, experienced drivers aged 23 to 61, were randomly assigned to four experimental conditions (telephone and easy or hard driving task versus control and easy or hard driving task). Contrary to the predictions, the strongest effects were found when the subjects were exposed to the easy driving task. In the condition where drivers had to perform the easy driving task, findings showed that a mobile telephone task had a negative effect on reaction time and led to a reduction of the speed level. In the condition where drivers had to perform the hard driving task, findings showed that a mobile telephone task had an effect only on the drivers' lateral position. Finally, the mobile telephone task led to an increased workload for both the easy and the hard driving task. The results are discussed in terms of which subtask, car driving or telephone task, the subjects gave the highest priority. Some implications for information systems in future cars are discussed

    Incident warning systems and traffic safety: a comparison between the PORTICO and MELYSSA test site systems2000In: Transportation Human Factors, ISSN 1093-9741, Vol. 2, no 1, p. 77-93Article in journal (Refereed)
    Abstract [en]

    In this study we compared the effects on traffic safety of 2 different incident warning systems (IWSs), capable of presenting warning messages with different levels of detail. It was assumed that an IWS presenting a message with a low level of detail (i.e., "Warning") would produce a higher variation in driver behavior compared to a system that presented more detailed information (i.e., "Warning, in 1 km, use left lane"). The assumption was tested in a simulator study in which the Portuguese Road Traffic Innovations on a Corridor and Mediterranean Lyon Stuttgart Site for Advanced Transportation Telematics test site systems were simulated and used to present information that varied in level of detail in 4 steps. Fifty participants drove an 80-km route on a 2-lane motorway, where 3 different incidents occurred at randomly chosen distances from the starting point. The results showed that all IWSs made the participants reduce their speed level earlier compared to the control group. Subjective assessment of the IWS showed positive effects, and there was a tendency of a reduction of mental workload caused by the IWS. The assumption that a low level of detail in a message from an IWS would cause a higher variation in the participants' behavior, compared to a message with more detailed information, was not supported. Specific information from an IWS (i.e., "Change lane") resulted in 2 different strategies: One implied that the participant should trust and obey the recommendation, and the other implied that the participant should wait until the warned-for incident was visible and then follow the advice. The implications for the design of IWSs, as a consequence of the results from this study, are discussed

    Abstract [en]

    The effects of a mobile telephone task on young and elderly drivers' choice reaction time, headway, lateral position, and workload were studied when the subjects were driving in a car-following situation, in the VTI driving simulator. It was found that a mobile telephone task had a negative effect upon the drivers' choice reaction time, and that the effect was more pronounced for the elderly drivers. Furthermore, the subjects did not compensate for their increased reaction time by increasing their headway during the phone task. The subjects' mental workload, as measured by the NASA-TLX, increased as a function of the mobile telephone task. No effect on the subjects' lateral position could be detected. Taken together, these results indicate that the accident risk can increase when a driver is using the mobile telephone in a car following situation. The reasons for the increased risk, and possible ways to eliminate it, are also discussed.

    Abstract [en]

    The effects of mobile telephone use on traffic safety is discussed in the article. A number of empirical studies are reviewed and it is concluded that the use of a mobile telephone concurrently with car driving may have a negative impact upon traffic safety. The sub-tasks of entering a telephone number and having a demanding conversation are especially likely to increase the risk of an accident. To minimise the negative impact from telephoning on traffic safety, a number of recommendations are suggested.

    The aim of this paper is to make a review of studies concerning problems with alarm systems and to make a theoretical analysis of these problems. The aim is also to show some general design ideas to improve alarm presentation in process descriptions. Using research results from situation awareness and decision making a number of suggestions for further development of alarm systems are presented. Recommendations include providing operators of complex systems feedback that can support their mental models and situational awareness. Furthermore a recommendation is to design alarm systems that can learn from experience

    Human factors aspects on joystick control of adapted cars2002In: Human factors in transportation, communication, health and the workplace: annual scientific meeting of the Europe Chapter of the Human Factors and Ergonomics Society, Turin, November 7 to 9, 2001 / [ed] D. de Waard, Shaker Verlag, 2002, p. 81-97Conference paper (Refereed)
    Abstract [en]

    An experiment was set up to investigate different joystick designs based on steer-by-wire technology. The experiment was carried out in a driving simulator. Both driving behaviour and perceived control of the car was registered and analysed. All participants had an SCI (spinal cord injury) at cervical level, i.e. drivers with tetraplegia. Two types of joystick were tested, one conventional (similar to what is used with computer games) and one modified with which the driver could control speed and steering independently. Both joysticks were tested with and without active feedback. The driving task consisted of rural road driving and a manoeuvre test with a double lane-change. The results presented here should be considered as preliminary and the study as a pilot study, which will be completed with a larger set of participants. So far, eight subjects have completed the experiment. The preliminary results cannot be used to draw any definite conclusion on which system design should be preferred. There was some evidence that active feedback provided a better lateral control and the drivers drove with larger safety margins with the modified joystick. However, the drivers' opinion seemed to be more in favour of the conventional passive joystick.
