  • People and parking requirements : Residential attitudes and day-to-day consequences of a land use policy shift towards sustainable mobility
  • 2017
  • Ingår i: Land use policy. - : Elsevier. - 0264-8377 .- 1873-5754. ; :62, s. 213-222
  • Tidskriftsartikel (refereegranskat)abstract
    • A land use policy shift is taking place in a growing number of cities regarding parking, whereby a conventional supply management approach is being replaced with a parking management approach. As part of this policy shift, many cities are lowering their parking requirements.This study analysed changes in car use, car ownership, spatial parking patterns and the consequences for the everyday life of residents in a housing area with a relatively restrictive parking requirement in Gothenburg, the second largest city in Sweden. The housing area, a concrete example of how lowering parking requirements can be used to achieve targets on reduced car use and sustainable urban development, is used to discuss how parking policy should be applied to achieve the desired effect.The results show that the consequences of the restrictive requirement was paradoxically small in the study area. In practice, the requirement did not result in a decrease in the number of parking spaces, because e.g. of access to parking in neighbouring residential areas. This shows how important it is to adopt a holistic approach in parking policy, by e.g.introducing more restrictive parking requirements in parallel with other measures, such as raising parking charges and decreasing the number of public parking spaces. It also shows that planning of parking must be coordinated with other urban planning functions. Otherwise, the actual contribution of a shift in parking policy to the development of a more environmentally friendly transport system and city risks being small, despite lower parking requirements

  • Personvern og ITS-baserte trafikksikkerhetstiltak : en studie av streknings-ATK, automatisk fartstilpasning (ISA) og atferdsregistrator (EDR)
  • 2010
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Nye ITS-baserte trafikksikkerhetstiltak som kan brukes til å registrere og regulere uønsket atferd i trafikken, har et stort potensial for å øke trafikksikkerheten. Men de kan komme i konflikt med personvernet. Streknings-ATK og EDR har klare implikasjoner for personvernet og at ISA kan ha det om data fra ISA-systemet lagres. Konsekvensene for personvernet er tolket ulikt i Norge og Sverige. Prøvedrift med streknings-ATK på flere strekninger er startet opp i Norge, men i Sverige er dette ikke aktuelt pga. hensynet til personvern. I begge land installeres ISA i offentlige tjenestebiler. EDR har fått liten oppmerksomhet i begge land. Bileierne er overveiende positive til både streknings-ATK og ISA. Jo større forståelsen for at fart er en risikofaktor, desto større er aksepten for slike fartsregulerende tiltak. Bileierne er mest skeptiske til atferdsregistratorer som i dag er lite kjent. Atferdsregistratorer, som ?event data recorder? eller ?black box?, er imidlertid i ferd med å bli svært vanlige i moderne biler ? og stadig mer data fra kjøretøyene lagres. Bileiere bør derfor i større grad få informasjon om dette og tilgang til de data som registreres.

  • A study of changes in everyday mobility during the Covid-19 pandemic : As perceived by people living in Malmö, Sweden
  • 2021
  • Ingår i: Transport Policy. - : Elsevier. - 0967-070X .- 1879-310X. ; 106, s. 109-119
  • Tidskriftsartikel (refereegranskat)abstract
    • Sweden's strategy to manage the spread of Covid-19 has not included any form of lockdown, in contrast to the approaches adopted by most other countries. Instead, the strategy has been largely based on strong recommendations for society. Even though Sweden has not had any form of lockdown, the Covid-19 pandemic has during a relatively short period of time brought changes for society, significantly disrupting everyday life. The pandemic poses both challenges and opportunities for sustainable future transport, not least public transport provision, supply and use. The purpose of this study is to investigate how changes for society have translated into changes for mobility as an element of everyday life during the early stages of a pandemic. This study draws on a map-based online survey (public participatory GIS) which was purposefully designed to allow people to contribute with their experiences in order to capture how the current situation has affected several different facets of people's everyday life. Results suggest that effects on mobility, such as the possibility to telework, affect different groups differently and may exacerbate existing differences in terms of gender, geography and mobility. In order to mitigate negative effects, transport policy needs to be tailored in order to take these heterogeneities into account. Both spatio-temporal adjustment and modal adjustment were dominant themes for most activities, although the dominance of these themes varied among the activities. Our findings give an indication of both the short and long-term impacts on everyday mobility in the Swedish context, for groups of inhabitants in the city of Malmö. Through deepening our understanding of the processes at play, we suggest eight possible policy responses that can be carefully tailored, both in the interim and into the future.

  • A climate report gone missing : power mechanisms in Swedish national transport planning
  • 2024
  • Ingår i: European Planning Studies. - : Routledge. - 0965-4313 .- 1469-5944. ; 32:6, s. 1423-1441
  • Tidskriftsartikel (refereegranskat)abstract
    • While the technological development of vehicles and fuels is not adequate to meet current climate mitigation targets, infrastructure development also plays an important role in transforming the transport system. Previous studies have argued that conventional infrastructure planning is incapable of implementing climate mitigation. The aim of the paper is to provide insights into power means and mechanisms that counteract integration of climate mitigation targets in infrastructure planning. This is done by an in-depth case study of current Swedish national transport planning. This case provides a rich illustration of a situation with high political ambitions regarding climate mitigation on the one hand, and power mechanisms and resistance with regard to climate goals during the planning process on the other. The case is analysed using the perspective of power circuits and shows how forecasting works as an obligatory passage point, sorting in and out which analyses will be part of the decision-making material. Analyses which do not fit the forecasting model are dismissed from planning. The conclusion is that as long as the transport infrastructure planning practice is dependent on forecasting as the only central analysis there will be difficulties in changing the scope of infrastructure planning and making climate goals central for transport planning.

  • Co-operation between police and social treatment services offering treatment to drink and drug drivers : experience in Sweden
  • 2011
  • Ingår i: Traffic Injury Prevention. - : Informa UK Limited. - 1538-9588 .- 1538-957X. ; 12:1, s. 9-17
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To describe and analyze a measure that has been introduced in Sweden with the objective of quickly offering treatment for the alcohol or drug problems suspected drink or drug drivers may have. The goal of the measure is that every suspected drink or drug driver shall, as soon as apprehended by the police, be offered contact with the social services or the dependency care and treatment service, which can offer a consultation and, if needed, suitable treatment.Method: Interviews and questionnaire surveys, as well as forms that describe the treatment received by each individual case.Results: About 20 percent of all those who receive the offer from the police accept contact with the social services or the care and treatment service, and approximately 40 percent of these also attend the consultation. There is a favorable fundamental attitude to the method among the participating authorities. However, some shortcomings in application are revealed. One example concerns drug drivers who are offered contact with the social services or the care and treatment service to a considerably lesser extent than drink drivers. Another neglected group are the people who are at first suspected of drink driving but are later found to have an alcohol concentration below the legal limit. Compared with those who have an alcohol concentration above the legal limit, this group is offered contact to a lesser extent and also have a lower propensity to accept the offer.Conclusions: The results indicate a strong support for the method from involved authorities, but participation could be improved by giving more attention to neglected groups.

  • The Swedish Joint Action Method against Drink Driving : A Study of Suspected Drink Drivers' Own Experiences
  • 2016
  • Ingår i: Traffic Injury Prevention. - : Taylor & Francis. - 1538-9588 .- 1538-957X. ; 17:6, s. 558-563
  • Tidskriftsartikel (refereegranskat)abstract
    • In Sweden, a joint action method called SMADIT is in use, where the police quickly offer help from the social services or the dependency care and treatment service to suspected drink drivers. One conclusion from this paper is that SMADIT, as an innovative method that can be deployed more rapidly than other alcohol-impaired driving countermeasures, should be considered as a good complement to conventional methods to deal with drink driving.The objective of this paper is to analyse the experiences of suspected drink drivers who accepted the offer of help, and what it meant for them. To enable comparisons over time, in-depth interviews were conducted with twelve suspected drink drivers on two occasions with one year between.To varying degrees the informants knew about their alcohol problems, but were unsure if they would have sought help by themselves. Therefore, the original ideas of the method with an initial contact with the social services or the dependency care and treatment service within 24 hours, was found to be important. However, the results also showed that some of the informants needed some time before the first meeting as they were in shock from the drink driving incident or in need of sleep.Results also shows that an encouraging attitude among the police, the social services, and the dependency care and treatment service is important for the success of the SMADIT method. The informants are satisfied with the method, and in retrospect the incident and the SMADIT offer of help are described as a turning point in their lives. One year after being offered help the informants had gained insights into the harm they could have done to other road users when they drove while drunk.

  • Decomposing cycling potentials employing the motility framework
  • 2021
  • Ingår i: Journal of Transport Geography. - : Elsevier. - 0966-6923 .- 1873-1236. ; 91
  • Tidskriftsartikel (refereegranskat)abstract
    • The concept of motility, mobility capital, has been put forward to understand mobility from a more holistic perspective through incorporating subjective and objective as well as material and non-material aspects in the examination of individuals' mobility potentials. In this paper, building on a survey study in the two municipalities of Malmö and Gothenburg in Sweden, I developed a quantitative operationalization of motility in relation to cycling and employed GIS-based and statistical analyses to identify a set of appropriate indicators to measure the three dimensions of cycling motility namely access, competence, and appropriation. The analyses reveal three operational dimensions underlying the process of appropriating cycling to carry out daily trips. More specifically, individuals' perceptions of the functional and social suitability of cycling and its compatibility with their principles and values seem to be significant for the appropriation of a bike as a daily travel mode. Altogether, the findings support that the quantitative operationalization of cycling motility can deepen our understanding of the factors shaping individuals' cycling potentials and practices, hence offering valuable insights into the development of successful cycling interventions that create material and nonmaterial infrastructure, competences, and positive representations necessary for the appropriation of cycling.

  • Examining Inequalities in Cycling Motility : A Pathway Towards Cycling Justice
  • 2023
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Realizing the environmental and social benefits of cycling requires effective policies that deliver increased and inclusive cycling. This thesis aims to contribute to the development of such policies by providing insights into what could make cycling achievable for more diverse social groups through engaging with theoretical perspectives from transport geography, the mobilities paradigm and social justice. In doing so the thesis examines the various elements that constitute an individual’s potential to use a bicycle and the connected inequalities.The thesis employs conceptions of accessibility and motility in combination with measures of inequality to examine the socio-spatial inequalities in cycling potentials. The first paper designs a new composite indicator based on Theil’s index of inequality and accessibility measures to study inequalities in bike-and-ride opportunities in Malmö. The second paper develops a quantitative operationalization of cycling motility by applying GIS-based and statistical analyses to empirical data collected using a survey study. Specifically, cycling motility is operationalized along three dimensions of access, competence, and appropriation. This is done by measuring cycling-related material and nonmaterial, as well as objective and subjective factors related to individuals and their social, cultural, and geographical environment.The subsequent papers put the concept of cycling motility in practice. The third paper builds on the approach developed in the second paper and examines inequalities in the cycling motility across different social groups from the three-dimensional justice lens of Nancy Fraser. Finally, the fourth paper provides insights into the relationships between individuals’ cycling motility and their realized mobility. The empirical findings highlight that such relationships vary across three urban contexts of Malmö, Gothenburg, and Beijing. Overall, the findings support that the operationalization of cycling motility is useful for studying individuals’ cycling potentials and capturing the connected between-individual differences, thereby helpful for development of policies that could realize the social and environmental potentials of cycling.

  • Inequalities in access to bike-and-ride opportunities : Findings for the city of Malmö
  • 2019
  • Ingår i: Transportation Research Part A. - : Elsevier. - 0965-8564 .- 1879-2375. ; 130, s. 673-688
  • Tidskriftsartikel (refereegranskat)abstract
    • Bike-and-ride – that is, integrating cycling and public transport in one trip – is an attractive combination, as cycling as an active and clean mode is faster than walking and more affordable and flexible than other alternative modes of transport. Using cycling as a feeder mode to public transport could potentially allow people to reach more opportunities and improve their mobility, and ultimately, their well-being. Therefore, it is relevant to investigate the inequalities in access to bike-and-ride options across population groups.In this context, we suggest assessing the inequalities in bicycle access to the main transport hubs of a city by developing a composite indicator based on accessibility measures and the Theil index of inequality. This indicator captures the role of both private and public bikes – part of a Bike Sharing System (BSS) – in accessing the existing public transport system. The novelty of our approach lies in bringing the distributional justice perspective in the accessibility evaluation of transport and analysing the inequalities within and between any arbitrarily defined population groups. Moreover, in addition to travel time by bike, this accessibility measure incorporates a series of bike-related features, such as the typology of bike lanes (separated from or shared with roads), the presence of a BSS in the network, and bike facilities (e.g., parking racks) in transport hubs.The proposed methodology is applied to a real case study of the city of Malmö, Sweden, to prove its efficacy and usefulness. In particular, we examine how the level of bicycle access to the major public transport destination (including train stations and regional bus hubs) varies across the population. While considering the contextual properties of the city of Malmö, the inequalities are analysed in relation to spatial dimension and social background of the population, it is possible to extend the proposed analysis by including further features of the population, such as income or gender, and apply the same approach to different contexts.
