Designing the S in MaaS: Behind the scenes and beyond the screens
- 2022
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- There is a considerable number of academic as well as non-academic publications on different aspects of Mobility-as-a-Service (MaaS). Several studies, with a Stated Preference approach, have investigated e.g. who the potential users of MaaS may be, what modes should be offered and users’ willingness to pay. Other researchers have tried to describe the challenges associated with the development and implementation of MaaS including technical issues, legislation and regulation barriers, lack of appropriate business models, etc. There are also those few who report on results of MaaS pilots and how the service elements influenced the outcome. MaaS is not merely a digital application but a complex service, where several mobility service providers need to collaborate in order to offer a service which “… not only integrates a range of mobility services, both public and private, but also provides one-stop access to all services through a common interface.”. It is therefore surprising that design process per se, or the methodology used have not been the focus for research efforts. Purpose: This study explains a small-scale MaaS development project with the service design process in focus. What process was followed and why? What methods and tools were used? How were stakeholders involved? Etc. Methodology: The scope of study is a local business-to-business MaaS solution designed for employees at multiple organizations (B2B-E), all closely located in an urban area. The design and development of the service were studied from the beginning until final implementation over the course of two years. Data sources include semi-structured interviews with stakeholders, participatory observations of project meetings, and a series of stakeholder workshops reflecting on the MaaS design process. Findings:The results evidence the need for design guidelines for MaaS with a focus on the service aspect, i.e. the S in MaaS. When analysing the process, most stakeholders realized that important steps were missing or completed in the wrong order. Several general service design principles were not fully implemented, for example results show that not all interaction points in the customer journey were considered in the design (designing for these critical points requires alignment between digital and physical touchpoints; employees’ actual trips often differed from those which the service was intended for, and service ownership and allocation of stakeholders’ responsibilities were not altogether clear. The results highlight the wide range of responsibilities of the MaaS provider, such as maintaining MaaS physical and digital infrastructure, ensuring universal provision of information, and negotiating and coordinating regulations and policies between public and private bodies. Implications: To provide MaaS is beyond developing and administrating a mobile app or similar end-user digital touch points. It requires physical infrastructure, such as mobility hubs, unified information design of both physical and digital infrastructure, and understanding of multiple user groups , including (in the specific case) individuals as well as organizations. To do so, service design models and methods tailored for complex services are required. Such methods should address high level design challenges including service ownership, stakeholder responsibilities, and evolving business models.

Objective functions for plug-in hybrid electric vehicle battery range optimization and possible effects on the vehicle fleet
- 2018

Ingår i: Transportation Research, Part C: Emerging Technologies. - : Elsevier BV. - 0968-090X. ; 86, s. 655-669

Tidskriftsartikel (refereegranskat)abstract
- While a hybrid electric vehicle (HEV) mainly runs on the same fuel as a conventional combustion engine, a plug-in hybrid electric vehicle (PHEV) has the potential to replace most of that fuel with electricity from the grid. Further, the driving-range limitations associated with a pure battery electric vehicle (BEV) do not apply to the PHEV. This makes the PHEV an interesting option for reducing greenhouse gas (GHG) emissions and local air pollutants as well as energy dependence, without sacrificing performance. However, how large fuel reduction that could be expected from PHEVs strongly depends on the battery range and driving and charging patterns (Björnsson and Karlsson, 2015). To maximize fuel reduction, battery capacity should be designed to reach a high share of electric driving. However, maximizing fuel reduction might not be the main objective for all stakeholders when optimizing battery range. Car owners could be more interested in reaching a low total cost of ownership (TCO), while manufacturers might focus on a battery range that suits as many potential buyers as possible. In this study, we analyze how the optimal battery range for the PHEV and the resulting vehicle fleet properties vary with the choice of objective function under various techno-economic conditions and policy options.

Trafikverket på kollisionskurs med klimatmålen
- 2015
-
Ingår i: Göteborgs Posten. - 1103-9345. ; :2015-12-12
-
Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Trafikverket räknar med en kraftig ökning av trafiken för både personbilar och lastbilar i sin nya infrastrukturplan, detta trots att Sveriges klimatmål kräver raka motsatsen. Det finns anledning för regeringen att snarast ge Trafikverket tydliga direktiv att i sin planering utgå från att klimatmålen ska nås, skriver en lång rad professorer och forskare.

Integrating Entrepreneurial Experiences with Sustainable Development Education
- 2019
-
Konferensbidrag (refereegranskat)abstract
- The purpose of this study was to address the challenge of teaching sustainable development to computer engineering students. Part of the problem is that they perceive the topic as irrelevant for their future profession. The chosen approach was to introduce a project element into a course on sustainable development where the students developed applications for sustainable mobility together with the local public transport authority, an academic institution and a multinational telecom company. Thus the course project was organized to facilitate entrepreneurial experiences, as defined in the EU's EntreComp model, as well as relating theoretical concepts to experiences in a concrete context. The students were then asked to analyze and reflect upon their design choices and approaches in relation to sustainable development and ethical considerations. The findings conclude that the course changes improved the overall student satisfaction while succeeding in anchoring sustainable development in a context the students could relate to. The collaboration was also perceived as fruitful by the external stakeholders who encouraged the students to stay in touch for their bachelor theses and internships. The theoretical implication is a first attempt in integrating sustainable development education with entrepreneurial experiences while the practical implication is a description of how the integration can be realized. The contribution is therefor of value for both educational researchers by opening novel research opportunities and teachers by describing new possibilities for sustainable development education.

- Purpose: The purpose of this study is to address the challenges of teaching sustainable development to computer engineering students. Part of the problem is that they perceive the topic as irrelevant for their future profession. Design/methodology/approach: To address this challenge, we introduced a project element into a course on sustainable development where the students developed applications for sustainable mobility together with the local public transport authority, an academic institution and a multinational telecom company. Findings: The findings conclude that the course changes improved the overall student satisfaction while succeeding in anchoring sustainable development in a context which the students can relate to. The collaboration was also perceived as fruitful by the external stakeholders who encouraged the students to stay in touch for their bachelor theses and internships. Research limitations/implications: The theoretical implication is a first attempt in integrating sustainable development education with entrepreneurial experiences, whereas the practical implication is a description of how the integration can be realized. Practical implications: The contribution is therefore of value for both educational researchers to open novel research opportunities and for teachers to describe new possibilities for sustainable development education. Originality/value: The contribution describes how entrepreneurial experiences can be used to motivate engineering students in mandatory courses on sustainable development and ethics. The approach is novel in that the approach has not been described earlier in this context.

Statistical Data for Free-floating Car Sharing versusPublic Transport
- 2017
-
Konferensbidrag (refereegranskat)abstract
- Free-floating car sharing is a form of car rental used by people for short periods of time where the cars canbe picked up and returned anywhere within a given area. In this paper, we have collected free-floating carsharing data, for electric as well as fossil fueled cars, and data for alternative trips using cycling, walking andpublic transport for the cities of Amsterdam, Berlin, Denver, Madrid, San Diego and Seattle. From this data,free-floating car sharing seems to be a compliment to other type of transports, including public transports,bicycling and walking, and not a competitor.
