  • Users in Action. Stories of Users and Telematics in Everyday Life
  • 1999
  • Samlingsverk (redaktörskap) (övrigt vetenskapligt)abstract
    • Detta är en antologi som består av exempel på empiriska studier där äldre människors varit involverade som subjekt. Resultatet visar att äldres teknikanvändning i vardagen problematiseras på tre nivåer. den första nivån fokuserar konstruktionen och utformningen av artefakten; den andra nivån användningen av tekniken i den vardagliga kontexten; den tredje nivån relationen mellan teknikutvecklingen och användaren som samhällsvarelse.

  • A media campaign aiming at reducing delay times and increasing the use of ambulance in AMI.
  • 1994
  • Ingår i: The American journal of emergency medicine. - : W.B. Saunders Co.. - 0735-6757 .- 1532-8171. ; 12:3, s. 315-8
  • Tidskriftsartikel (refereegranskat)abstract
    • To improve the prognosis in patients with acute myocardial infarction (AMI) if treatment by early instituting treatment, we initiated a media campaign during 1 year with the intention to reduce delay times and increase ambulance use in patients with acute chest pain. This article describes the outcome during 3 years after the campaign was finished. The median delay time in patients with AMI was reduced from 3 hours 0 min before the campaign to 2 hours 20 minutes during the year of the campaign (P < .001). The median delay time remained at a similar level (2 hours 20 min) during the 3 years after the campaign. Ambulance use was not affected during or after the campaign. It can be concluded that a media campaign resulted in a reduction of delay times not only during the campaign, but also during 3 years after its performance, whereas ambulance use was not affected.

  • Governing Mobility as a Service: Insights from Sweden and Finland
  • 2019
  • Ingår i: Institutionella ramverk för integrerade mobilitetstjänster i framtidens städer - IRIMS. - Cham : Springer International Publishing. ; , s. 169-188
  • Bokkapitel (övrigt vetenskapligt)abstract
    • Based on a review of recent developments in Sweden and Finland, this chapter analyzes the roles of public organizations in the governance of a transition to Mobility-as-a-Service (MaaS). In particular, we draw on insights from transition frameworks to explore what these two pioneering cases can teach us about how the public sector can both enable the development of MaaS and steer the development trajectory toward diffusion of MaaS offerings that contribute to transport policy goals. We propose three main points. Firstly, public sector organizations at national, regional, and local levels have key roles to play in potential transitions to MaaS, regardless of their intended operative roles in the emerging MaaS ecosystem. Secondly, a central task for public sector organizations is to align operational and tactical MaaS governance activities with both an overarching MaaS strategy and with other relevant strategies, such as transport infrastructures investments, programs for economic and industrial growth, city plans, and parking norms. Thirdly, new models and tools for public–private collaboration are needed in order to effectively govern the development and diffusion of sustainable MaaS.

  • Intermediary MaaS Integrators: A Case Study on Hopes and Fears
  • 2020
  • Ingår i: Transportation Research Part A: Policy and Practice. - 0965-8564 .- 1879-2375. ; 31, s. 163-177
  • Tidskriftsartikel (refereegranskat)abstract
    • At present, many policymakers and practitioners are searching for actions that could facilitate Mobility as a Service (MaaS) developments. A potential action, which has received a lot of attention, is to introduce Intermediary MaaS Integrators; that is intermediate actors that assemble the offerings from Transport Service Providers (TSPs) and distribute these to MaaS Operators. However, little is known about if and how TSPs and MaaS Operators would appreciate the introduction of Intermediary MaaS Integrators. To address this knowledge gap, this paper explores an attempt to establish a national Intermediary MaaS Integrator in Sweden. The contribution to transportation research is twofold. Firstly, the paper advances the conceptual understanding of Intermediary MaaS Integrators by identifying four defining dimensions: Activities, Management, Processes and Context.Secondly, it deepens the knowledge of Intermediary MaaS Integrators’ value propositions by detailing TSPs’ and prospective MaaS Operators’ hopes and fears vis-à-vis them. Lastly, practical implications for how to facilitate acceptance and adoption are proposed. Intermediary MaaS Integrators should only be introduced if basic incentives for using their services are in place, and if introduced, they should preferably: go beyond offering technical services; have clear, declared objectives; be impartial and capable actors; and carefully consider their launch strategies.

  • End-users' acceptance and use of adaptive cruise control systems
  • 2014
  • Ingår i: Karwowski, T.A. & Marek, T. (eds), Proceeding of the 5ht International Conference on Applied Human Factors and Ergonomics 2014, Krakow, Poland, 19-23 July 2014.
  • Konferensbidrag (refereegranskat)abstract
    • An online survey was distributed to end-users of adaptive cruise control (ACC). In total 90 drivers answered the questionnaire, which covered e.g. ACC usage and how such use affects driver behaviour. According the responses: the ACC is used primarily on roads with higher speed limits; the end-users trust the system even though it has some functional limitations; they have a very positive attitude towards the system; and positive effects on comfort and safety are observed including reduced inclination to overtake and increased compliance with speed regulations.

  • Exploring end-user experiences : self-perceived notions on use of adaptive cruise control systems
  • 2011
  • Ingår i: IET Intelligent Transport Systems. - : Institution of Engineering and Technology. - 1751-956X .- 1751-9578. - 9782953171211 ; 5:2, s. 134-140
  • Tidskriftsartikel (refereegranskat)abstract
    • This study explores end-user experiences of adaptive cruise control (ACC) systems. A qualitative approach has been applied and data have been collected by means of focus group interviews. A qualitative content analysis was carried out to analyse and interpret collected data. In total the study consists of three focus group sessions with five to seven participants in each. Themes explored include interaction between user and system, functional limitations and trust, and system effects on driving behaviour. Key findings include reported driving behaviour changes as, for instance, an increasing tendency to stay in the right lane as well as users' conception of system functionality from which it can be concluded that end-users of ACC carry rough mental models of the system. A potentially hazardous situation for other road-users following the use of ACC is highlighted and discussed. In addition, some features desired by the end-users are discussed, for example, the call for conventional cruise control functionality when owing to weather conditions functional limitations are apparent.

  • Semi-automated versus highly automated driving in critical situations caused by automation failures
  • 2014
  • Ingår i: Transportation Research Part F: Traffic Psychology and Behaviour. - 1369-8478 .- 1873-5517. ; 27:PB, s. 218-228
  • Tidskriftsartikel (refereegranskat)abstract
    • The purpose of this study was to examine the effects of vehicle automation and automation failures on driving performance. Previous studies have revealed problems with driving performance in situations with automation failures and attributed this to drivers being out-of-the-loop. It was therefore hypothesized that driving performance is safer with lower than with higher levels of automation. Furthermore, it was hypothesized that driving performance would be affected by the extent of the automation failure. A moving base driving simulator was used. The design contained semi-automated and highly automated drivingcombined with complete, severe, and moderate deceleration failures. In total the study involved 36 participants. The results indicate that driving performance degrades when the level of automation increases. Furthermore, it is indicated that car drivers are worse at handling complete than partial deceleration failures.
