- This article deals with the organisation of correction in mobile instructional settings. Five sets of video data (>250 h) documenting how learners were instructed to fly aeroplanes, drive cars and ride bicycles in real life traffic were examined to reveal some common features of correction exchanges. Through detailed multimodal analysis of participants’ actions, it is shown how instructors systematically elaborate their corrective instructions to include relevant information about the trouble and remedial action – a practice we refer to as unpacking corrections. It is proposed that the practice of unpacking the local particulars of corrections (i) provides for the instructional character of the interaction, and (ii) is highly sensitive to the relevant physical and mobile contingencies. These findings contribute to the existing literature on the interactional organisation of correction and mobility, as well as to ongoing work in ethnomethodology and conversation analysis on teaching and learning as members’ phenomena.

- This article takes an interest in how students at a driving school areinstructed how to make the car's behaviour intelligible (accountable)to other road users in traffic. Taking the indicator as an example,the analytic focus is on the ways in which the indicator'srelevance is instructed and its timely activation practiced, andhow activating the indicator is instructed as part of moreencompassing turning procedures. The indicator is one of the centralresources built into cars for displaying to others a driver'sintention about where to go next. Although indicating does not,in itself, affect the movement of the car, activating the indicatoris crucial for allowing others to anticipate a car's movement inspace, and coordinate themselves with it. The analysis showshow instructors manage trainee drivers' instructed actions duringdriving by providing descriptions of what using the indicatoraccomplishes before a directive to turn (a), after a directive to turn(b), and as accounts for initiating correction of trainee driver carcontrol activity (c).

Tidskriftsartikel (refereegranskat)abstract
- Latent driver sleepiness may in some cases be masked by for example social interaction, stress and physical activity. This short-term modulation of sleepiness may also result from environmental factors, such as when driving in stimulating environments. The aim of this study is to compare two road environments and investigate how they affect driver sleepiness. Thirty young male drivers participated in a driving simulator experiment where they drove two scenarios: a rural environment with winding roads and low traffic density, and a suburban road with higher traffic density and a more built-up roadside environment. The driving task was essentially the same in both scenarios, i.e. to stay on the road, without much interaction with other road users. A 2 x 2 design, with the conditions rural versus suburban, and daytime (full sleep) versus night-time (sleep deprived), was used. The results show that there were only minor effects of the road environment on subjective and physiological indicators of sleepiness. In contrast, there was an increase in subjective sleepiness, longer blink durations and increased EEG alpha content, both due to time on task and to night-time driving. The two road environments differed both in terms of the demand on driver action and of visual load, and the results indicate that action demand is the more important of the two factors. The notion that driver fatigue should be countered in a more stimulating visual environment such as in the city is thus more likely due to increased task demand rather than to a richer visual scenery. This should be investigated in further studies.

An on-road study of sleepiness in split shifts among city bus drivers

- Bus drivers often work irregular hours or split shifts and their work involves high levels of stress. These factors can lead to severe sleepiness and dangerous driving. This study examined how split shift working affects sleepiness and performance during afternoon driving. An experiment was conducted on a real road with a specially equipped regular bus driven by professional bus drivers.The study had a within-subject design and involved 18 professional bus drivers (9 males and 9 females) who drove on two afternoons; one on a day in which they had driven early in the morning (split shift situation) and one on a day when they had been off duty until the test (afternoon shift situation). The hypothesis tested was that split shifts contribute to sleepiness during afternoon, which can increase the safety risks. The overall results supported this hypothesis. In total, five of the 18 drivers reached levels of severe sleepiness (Karolinska Sleepiness Scale ≥8) with an average increase in KSS of 1.94 when driving in the afternoon after working a morning shift compared with being off duty in the morning. This increase corresponded to differences observed between shift workers starting and ending a night shift. The Psychomotor Vigilance Task showed significantly increased response time with split shift working (afternoon: 0.337. s; split shift 0.347. s), as did the EEG-based Karolinska Drowsiness Score mean/max. Blink duration also increased, although the difference was not significant. One driver fell asleep during the drive. In addition, 12 of the 18 bus drivers reported that in their daily work they have to fight to stay awake while driving at least 2-4 times per month. While there were strong individual differences, the study clearly showed that shift-working bus drivers struggle to stay awake and thus countermeasures are needed in order to guarantee safe driving with split shift schedules.

Everyday Mobility and Travel Activities during the first years of Retirement
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Mobility is central to living an independent life, to participating in society, and to maintaining well-being in later life. The point of departure in this thesis is that retirement implies changes in time-space use and interruption in routines, which influence demands and preconditions for mobility in different ways. The aim of this thesis is to explore mobility strategies and changes in mobility upon retirement and how mobility develops during the first years of retirement. A further aim is to provide knowledge of the extent to which newly retired people maintain a desired mobility based on their needs and preconditions. The thesis is empirically based on travel diaries kept by newly retired people, and qualitative interviews with the same persons, and follow-up interviews three and a half years later. The results show that mobility is a way of forming a structure in the new everyday life as retirees by getting out of the house, either just for a walk or to do errands. Many patterns of everyday life remain the same upon retirement, but the informants also merge new responsibilities and seek new social arenas and activities. As a result, the importance of the car have not changed, but it is used for other reasons than before. After leaving paid work, new space-time constraints are created which influences demands for mobility. The study further shows that “third places” become important, especially among those who live alone, as they give an opportunity to being part of a social context and a reason for getting out of the house. The follow-up interviews revealed that declining health changes the preconditions for mobility. Daily walks had to be made shorter, and the car had to be used for most errands to where they previously could walk or cycle. However, mobility can also be maintained despite a serious illness and a long period of rehabilitation.

- Lack of public and political acceptance is the main barrier to introducing congestion charges. Here we compared the experiences of congestion charge introduction in the Swedish cities of Stockholm and Gothenburg, with the aimof explaining differences in political and public acceptance. The results showed the importance of procedural factors, such as the consistency of objectives in policy packages, communication and marketing efforts, and the use of public referendums, and of contextual factors, including urban form, level of congestion, and functioning of public transport. Important lessonswere drawn between the two cities, but primarily on how to design, rather than secure public acceptance for, a congestion tax scheme. To build acceptance for congestion charges, close attention must be paid to the local political and geographical context when designing and implementing such a scheme.

Sustainability transitions at the frontline. Lock-in and potential for change in the local planning arena

Tidskriftsartikel (refereegranskat)abstract
- This paper explores challenges and possibilities for integrating goals of long-term sustainable development into urban planning practice, with a specific focus on local institutional conditions for sustainability transitions. The analysis is based on a qualitative single case study of a large urban development process: the development of a new city district in Hyllie in the city of Malmö, Sweden. Hyllie was branded as a flagship project for sustainable urban development, with particularly high ambitions on climate neutrality and sustainable energy consumption. Several innovative elements were initiated in the development process, for instance the "climate contract" between the municipality and large energy companies. In the paper, this climate contract is discussed as an initiative with a promising potential for sustainability transitions. In practice, however, the outcome of the development in Hyllie in terms of sustainable development is ambiguous, since the district is also framed around luxury shopping, entertainment, and an ambition to attract visitors from a long distance. The Hyllie development illustrates pre-requisites for work on sustainable development in a decentralized and market-oriented planning context. Theoretically, the analysis is inspired by the multi-level perspective (MLP) and institutional theory. The results illustrate how the development process was shaped by a complex interplay between actors with differing agendas and targets at different stages in the process. These results are applied in a general discussion of challenges and possibilities for urban planning to contribute substantially to a transition to long-term sustainable development. Overall, the analysis demonstrates the importance of considering specific local institutional conditions in strategic work for long-term sustainability.

Mental models of driving and speed : biases, choices and reality

Tidskriftsartikel (refereegranskat)abstract
- This paper provides a review of research performed by Svenson with colleagues and others work on mental models and their practical implications. Mental models describe how people perceive and think about the world including covariances and relationships between different variables, such as driving speed and time. Research on mental models has detected the time-saving bias [Svenson, O. (1970). A functional measurement approach to intuitive estimation as exemplified by estimated time savings. Journal of Experimental Psychology, 86, 204-210]. It means that drivers relatively overestimate the time that can be saved by increasing speed from an already high speed, for example, 90-130km/h, and underestimate the time that can be saved by increasing speed from a low speed, for example, 30-45km/h. In congruence with this finding, mean speed judgments and perceptions of mean speeds are also biased and higher speeds given too much weight and low speeds too little weight in comparison with objective reality. Replacing or adding a new speedometer in the car showing min per km eliminated or weakened the time-saving bias. Information about braking distances at different speeds did not improve overoptimistic judgments of braking capacity, but information about collision speed with an object suddenly appearing on the road did improve judgments of braking capacity. This is relevant to drivers, politicians and traffic regulators.
