  • Ingår i: IEEE Conference on Intelligent Transportation Systems, Proceedings, ITSC. - 2153-0009 .- 2153-0017. ; , s. 6102-6107
  • Konferensbidrag (refereegranskat)abstract
    • This paper investigates the acceptance of shared, autonomous vehicles (SAVs) with participants who have been exposed to AV pilots in Sweden, with a specific focus on shared mobility and public transport contexts. The study aims to gain insights into individuals' attitudes, acceptance levels, and willingness to use autonomous vehicles (AVs) in shared mobility scenarios, particularly in the context of public transportation. The research methodology employed focus groups to gather qualitative insights from participants. The findings provide valuable insights into user perceptions and preferences, offering guidance for promoting SAVs and integrating them into public transport systems in Sweden.

  • Sharing anxiety is in the driver’s seat: Analyzing user acceptance of dynamic ridepooling and its implications for shared autonomous mobility
  • 2021
  • Ingår i: Sustainability. - : MDPI AG. - 2071-1050. ; 13:14
  • Tidskriftsartikel (refereegranskat)abstract
    • As connected, electric, and autonomous vehicle (AV) services are developed for cities, the research is conclusive that the use of these services must be shared to achieve maximum efficiency. Yet, few agencies have prioritised designing an AV system that focuses on dynamic ridepooling, and there remains a gap in the understanding of what makes people willing to share their rides. However, in 2017, the Australian transport authority Transport for New South Wales launched over a dozen trials for on-demand, shared public transport, including AVs. In this paper, we investigate the user willingness-to-share, based on experiences from one of these trials. Four focus groups (19 participants in total) were held in New South Wales with active users of either the trialled on-demand dynamic ridepooling service (Keoride) or commercial ridepooling (UberPool). Through thematic analysis of the focus group conversations, the cost, comfort, convenience, safety, community culture, and trust in authority emerged as factors that influenced the willingness-to-share. When presented with driverless scenarios, the focus group participants had significant concerns about the unknown behaviour of their co-passengers, revealing sharing anxiety as a significant barrier to the adoption of shared AVs. This paper identifies previously disregarded factors that influence the adoption of AVs and dynamic ridepooling and offers insights on how potential users’ sharing anxiety can be mitigated.

  • Deliverable 2: European MaaS Roadmap 2025. MAASiFiE project funded by CEDR.
  • 2017
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Executive summaryMobility as a Service for Linking Europe (MAASiFiE) is a two-year project funded by the trans-national research programme “Call 2014: Mobility and ITS” launched by the Conference of European Directors of Roads (CEDR). The project investigates the prerequisites for organizing user-oriented and ecological mobility services in order to provide consumers with flexible, efficient and user-friendly services covering multiple modes of transport on a one-stop-shop principle. In addition, opportunities to combine passenger and freight transport operations are included.The main expected result of the project is the European MaaS Roadmap 2025 to be defined in Work Package 2, which this deliverable, Nr 2, presents. WP2 can be considered as an umbrella interacting with WPs 3, 4 and 5. WP3 analysed MaaS state-of-the-art and value networks, and develops business and operator models. Results are presented in Deliverable Nr 3 – Business and operator models for MaaS. WP4 performed socio-economic and environmental impact assessments of MaaS, and proposes a set of key performance indicators of MaaS. These results are presented in Deliverable Nr 4 – Impact Assessment. WP5 analysed technological requirements and interoperability issues of MaaS, including usability aspects, presented in Deliverable Nr 5 – Technology for MaaS. The work in WP 2 was performed through a series of four workshops: Workshop 1 created national MaaS visions. Workshop 2 evaluated potential impacts of Maas based on national MaaS cases. Workshop 3 created national versions of Roadmap 2025 defining short- and medium-term actions and requirements to reach the visions created in the first workshop. Workshop 4 was an international workshop creating European Roadmap 2025, consolidating results and defining next steps in implementing MaaS. Workshop 4 was international, while the other workshops were organised similarly in Finland, Sweden and Austria.The European MaaS Roadmap 2025 defines short- (1-3 years) and medium-term (4-9 years) actions and transitions needed to reach the vision formed in the first workshop. The Roadmap is divided into four functional perspectives: drivers, markets, MaaS services and enablers. Each perspective presents the results using the following classification: Academia and R&D, Business, Infrastructure & built environment, Policy & regulation, Technology & data, and Society & culture. The Roadmap also indicates the most important components identified in the workshop for the future development of MaaS. Academia and R&D is mainly seen as an enabler for identifying best practices, conducting impact assessments, and developing living lab test environments. The business sector affects primarily market and MaaS services perspectives and acts as an enabler. Business is seen as responsible for e.g. creating new pilots and services, collaboration and new business models, and developing the one-stop-shop principle.Infrastructure & built environment is mainly seen as a driver for land use and the change of urban structures and space solutions resulting e.g. in fewer parking lots. Guidelines e.g. for city planning and infrastructure are considered as enablers for MaaS. Policy & regulation touches all functional perspectives by creating an environment enabling and promoting interoperability, collaboration, the MaaS ecosystem and achievement of policy targets. Regarding technology, key enabling technologies for MaaS exist, but challenges are related to e.g. interoperability and open interfaces, privacy and standardization.Society & culture aspects are mainly related to market and MaaS services perspectives. MaaS is expected to solve the life puzzle from the mobility perspective. Consumers can influence MaaS development depending on increased user acceptance and attitude change, as well as being a prosumer (producer/ consumer) by integrating e.g. private cars to the MaaS ecosystem.The continuity needed to regularly update the MaaS roadmap was seen as important, as the path of MaaS development is currently uncertain. Also impact assessments and validated results are needed to see the real quantitative impacts of MaaS.

  • Exploring automated vehicle driving styles as a source of trust information
  • 2019
  • Ingår i: Transportation Research Part F: Traffic Psychology and Behaviour. - : Elsevier BV. - 1369-8478. ; 65:August 2019, s. 268-279
  • Tidskriftsartikel (refereegranskat)abstract
    • Trust is important for users’ acceptance and adoption of automated vehicles (AVs). Previous research has mainly focused on what information affects user trust in AVs and how the user’s trust is affected by the way the content is communicated. However, recent studies have shown that trust may also be affected by the AV’s driving style. The aim of the study was to further investigate if and how the vehicle’s driving style affects user trust in AVs and, in particular, how this is expressed by users. An experiment involving 18 participants, using a Wizard of Oz setup and within a subject design, was conducted comparing two different driving styles, ‘Defensive’ and ‘Aggressive’. Trust was measured using a mixed method research design including momentaneous trust ratings and think-aloud procedures while driving, a post-run trust questionnaire as well as trust curve sketching and a personal interview. The results show that driving style had an effect on user trust and that the ‘Defensive’ driving style was perceived as more trustworthy, in part because it was deemed more predictable than the ‘Aggressive’ driving style. Furthermore, participants expressed trust in using affective, analogical and analytic responses, the two former during the test runs and the latter directly after each test run. The interview after the completion produced a more mixed result. By combining different data collection methods, a nuanced picture of the trust formation process and users’ trust in AVs was obtained. The study concludes that it is important to consider the vehicle performance information provided by the vehicle’s driving style so as to create user trust in AVs.

  • Understanding trust in an AV context: A mixed method approach
  • 2018
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Trust is a fundamental part of technology acceptance as well as an important factor for creating a positive user experience with Automated Vehicles (AVs). In order to fully understand users' trust in AVs it is important to consider the cognitive processes by which humans develop trust. We argue that a deeper understanding of these processes can be elicited by using a convergent mixed method design. The method design described in this paper was created during an experimental study investigating the effect of AV's driving behaviour on users' trust. The design consists of five data collection methods, three qualitative and two quantitative, used to collect data during and after test runs with an AV. The results show that the different methods elicited responses that may indicate different cognitive processes. The methods used during the test runs produced more affective and analogical responses while the methods used directly after each of the test runs generated more analytic responses. The last method, introduced after the completion of all test runs, produced a more mixed result. The participants elaborated on their earlier responses and sometimes turned their affective responses into analytic or analogical explanations. Hence, by combining and utilizing the strength of different data collection methods, more rich data was elicited on the trust formation process and thereby creating a more nuanced picture of users' trust in automated vehicles.

  • Customer Oriented Product Development? An exploratory study of four Swedish SME's
  • 2001
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • The purpose of this study was to investigate the degree of customer orientation in a small sample of Swedish SME's. In-depth interviews were carried out with product developers in four companies from three different product areas. The questions posed concerned the company's overall strategy, ways of managing the external dialogue (i.e. the dialogue between the company and the customer), and ways of managing the internal dialogue (i.e. the dialogue between the product development team members, and between the product development team and the company). The study indicates some ambiguities regarding key issues in customer orientation. All companies claimed to be customer-oriented, however, the meanings of the concept varied slightly between offering the customer what the customer wants' to understanding and solving customer problems'. The study also showed that the companies had difficulties defining their customer. While customer-orientation in general seems to imply a consumer-orientation, the customer can also be the middleman or the distributor. The latter was the case in three of the four companies and had clear implications on overall strategy. Also, the direct dialogue between the manufacturer and the end customers, i.e. consumers was rather limited, even though such a dialogue was considered and needed.
