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.

Tidskriftsartikel (refereegranskat)abstract
- Purpose – Mobility is an important aspect of well-being, activity and participation. Retiring from paid work is a transition in later life when people need to adjust to a new daily structure and fill the day with activities other than work. Life-course transitions influence demands for mobility and choice of travel mode as people adapt to new circumstances and learning processes. The purpose of this paper is to explore how mobility strategies develop during the first years of retirement.Design/methodology/approach – A qualitative analysis based on initial interviews with a total of 27 retired people during their first year of retirement and again, about three years later.Findings – Important changes during the first years of retirement included illness or a decline in physical health. Mobility had become a means of achieving certain goals after an illness, such as learning to walk, being able to drive or enjoying the time that was left. While some enjoyed not having commitments, others experienced difficulties in filling the day. The results indicate four dimensions of mobility: means of carrying out activities which are needed and desired; resources for creating activities; a leisure activity in itself; and subordinate to staying at home.Originality/value – Gives a deeper understanding of the mobility challenges people ultimately face in later life, and how these are managed, which is important for transport planning and public health policy aimed at improving mobility, activity participation and well-being in later life.

Tidskriftsartikel (refereegranskat)abstract
- The paper investigates whether and how regional public transport plans in Sweden address issues of social justice. Drawing upon a theoretical and analytical framework based on Young’s concept of domination and using a critical discourse analysis conducted on regional transport plans in three Swedish regions (Skåne, Stockholm and Västra Götaland), we identify discourses potentially resulting from and reproducing domination dynamics. The analysis highlights the centrality of economic growth goals and the framing of public transport users as customers not involved in the decision-making processes, which contradicts the declared justice and sustainability aims of the plans.

Tidskriftsartikel (refereegranskat)abstract
- In order to add to the existing knowledge on the complex institutional dynamics of negotiating conflicts and compatibilities in innovation processes that address societal challenges and social needs, this article scrutinizes the scientific and societal debate on the theoretical and practical application of “social innovation” by means of the concept “boundary object” linked to institutional theory. A participatory case study of the development of an R&I agenda for social innovation in Sweden, formulated through dialog between stakeholders from the public, private and non-profit sectors, is presented. The results show that the unpredictable, emergent, evolving and adaptable character of needs, challenges and solutions in social innovation processes is made more theoretically and practically manageable by acknowledging social innovation as a boundary object. This is since this concept, despite its ambiguous character, helps balance complexity and usefulness in a way that serves to expand existing knowledge on institutional dynamics.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper is concerned with one of the three requirements of a sustainable transport system, namely the environmental dimension. It starts by presenting components and interactions of the transport and traffic systems using causal diagrams. Generic traffic problems are identified and their causes categorized. A classification of demand and supply-based policies and measures that can be used in designing environmentally sustainable transport strategies is depicted. Such strategies are targeted towards minimizing the generic traffic problems encountered in metropolitan cities, i.e., traffic congestion, accidents, environmental degradation and energy inefficiencies. In this paper, Travel Demand and Land Use Management are considered as two of the basic pillars for designing environmentally sustainable transport strategies. Criteria for comparing demand versus supply-based policies are suggested. These are applied to assess the benefits and limitations of each policy, hence assisting decision makers in the prioritization and choice of such policies.

Performance of a one-camera and a three-camera system
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Driving and operating a vehicle is to a great extent a visual task. In driver behaviour studies it is therefore important to be able to measure where the driver is looking. Today this can be done unobtrusively and remotely in real-time with camera based eye tracking. The most common remote eye tracking systems use multiple cameras in order to give satisfactory results. However, promising results using only one camera has recently emerged on the market. The main objective of this study is to compare eye tracking systems with one and three cameras, respectively, during various measurement conditions.A total of 53 participants were enrolled in the study. Data from the two eye trackers were acquired and analysed in terms of availability, accuracy and precision. The results indicate that both availability and accuracy are affected by many different factors. The most important factors are the number of cameras that is used and the angular distance from straight ahead. In the central region (straight ahead) both one-camera and three-camera systems have a high degree of accuracy and availability, but with increasing distance from the central region, the results deteriorate. This effect falls harder upon the one-camera system. Interestingly, there were no significant effects when wearing glasses in either availability or accuracy. There was however an interaction effect between distance and glasses.Advantages with a one-camera system are that it is cheaper, easier to operate and easier to install in a vehicle. A multi-camera system will, on the other hand, provide higher availability and accuracy for areas that are far from the road centre. A one-camera system is thus mostly suitable for in-vehicle applications such as systems that warn drivers for sleepiness or distraction while multi-camera solutions are preferable for research purposes.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Dhaka, the capital city of Bangladesh, is the most vulnerable city both in terms of total number of accidents and accident rates. A total number of 2,720 accidents occurred during 2007-2011. This has caused a total of 1,481 numbers of pedestrian fatal accidents with 1,562 pedestrian fatal casualties. The primary objective of the paper is to study the characteristics of the road traffic accidents in Dhaka. The study area for this study is Dhaka Metropolitan Area. The paper focused on a few selected parameters a) Trend in overall accident rates b) Monthly variation of accident rates c) Accidents by severity levels d) Collision types e) Accidents in different lighting conditions. The raw data in the form of Accident Report Forms (ARFs) were collected from Dhaka Metropolitan Police (DMP). A GIS database was prepared for accidents showing locations and details for the period of 2007-2011. The analysis showed that on an average, the total number of traffic accidents is reduced by 11% each year. No profound effect of weather/season on road accidents is found. Fatal accidents and motor collisions are decreasing while injury accidents are increasing. Most traffic accidents: cause fatality (69%) and hit a pedestrian (60%). Fifty four percept of the accidents occurred during daytime. The paper recommends improvement measures for the road accident data collection and management system in Dhaka, Bangladesh. That includes the training need for the police staff, need for a geo-referenced database for data storage and management and involvement of multiple agencies in the process. This paper also recommends further studies on the extent and characteristics of underreporting of accidents.

Tidskriftsartikel (refereegranskat)abstract
- Almost all studies of sleepy driving are carried out in driving simulators and with monotonous road conditions (no interaction with other cars). The present study investigated indicators of sleepy driving in a more challenging scenario after a night awake. 17 participants drove a high fidelity moving base driving simulator experiment while sleepiness was monitored physiologically and behaviourally. Short periods of situations of free driving (no other vehicles) alternated with short periods of following another vehicle (car following) with and without the possibility to overtake. The result showed that a night of prior sleep loss increased sleepiness levels at the wheel (eye closure duration and lateral variability) compared to after a night of normal sleep. Blink duration while overtaking was significantly lower compared to the other situations, it was at the same level as after night sleep. Speed when passing a stopped school bus was not significantly affected by sleepiness. However the warning caused a more rapid reduction of speed. In conclusion, a moderately challenging driving contest did not affect sleepiness indicators, but a very challenging one did so (overtaking). This suggests that it is important to monitor the driving situation in field operational tests of sleepy driving.
