Using Blockchain in Peer-to-Peer Carsharing to Build Trust in the Sharing Economy (2019)
Bossauer, Paul ; Neifer, Thomas ; Pakusch, Christina ; Staskiewicz, Paul
Trust is the lubricant of the sharing economy, especially in peer-to-peer carsharing where you leave a valuable good to a stranger in the hope of getting it back unscathed. Central mechanisms for handling this information gap nowadays are ratings and reviews of other users. The rising of connected car technology opens new possibilities to increase trust by collecting and providing e.g. driving behavior data. At the same time, this means an intrusion into the privacy of the user. Therefore, in this work we explore technological approaches that allow building trust without violating the privacy of individuals. We evaluate to what extent blockchain technology and smart contracts are suitable technologies to meet these challenges by setting up a prototype implementation of a blockchain-based carsharing approach. In this context, we present our research approach and evaluate the prototype in terms of trust and privacy.

User Acceptance of Fully Autonomous Public Transport (2017)
Pakusch, Christina ; Bossauer, Paul
The development of fully automated vehicles is becoming more and more present in the social discussion. The image of fully automated cars is determined by automobile manufacturers and placed in the context of individual traffic. In contrast to fully autonomous private cars, fully automated public transport is already operating in some cities and is to be expanded in the future. Autonomous public transport offers great potential for the development and promotion of sustainable mobility concepts. However, the user acceptance is important for the enforcement and widespread use of these technical innovations. An online study on the acceptance of fully automated public transport based on quantitative data of a sample of N = 201 is presented. The results show a high level of familiarity with the topic and a very high level of overall intention to use fully automated public transport in the future.
Computergestützte Mobilitätsforschung (2016)
Pakusch, Christina ; Bossauer, Paul ; Meurer, Johanna ; Stevens, Gunnar
Mobilitäts- und Nachhaltigkeitsforscher sehen sich bei der Erforschung des Mobilitätsverhaltens von Personen mit einer bunten Palette an Erhebungsmethoden konfrontiert. Erweitert wird diese Vielfalt in der letzten Zeit durch die Möglichkeit, dieses Verhalten direkt über die Smartphones der Probanden zu erfassen. Um die Auswahl geeigneter Methoden zu erleichtern, liefert die vorliegende Literaturstudie einen detaillierten Überblick zu Fragestellungen, Daten und Erhebungsmethoden, die im Bereich der Mobilitätsforschung zur Erfassung von Alltagsmobilität eingesetzt werden.
From a Driver-centric towards a Service-centric lens on Self-Driving Cars (2016)
Stevens, Gunnar ; Meurer, Johanna ; Pakusch, Christina ; Bossauer, Paul
Within qualitative interviews we examine attitudes towards driverless cars in order to investigate new mobility services and explore the impact of such services on everyday mobility. We identified three main issues that we would like to discuss in the workshop: (I) Designing beyond a driver-centric approach; (II) Developing mobility services for cars which drive themselves; and (III) Exploring self-driving practices.

Dealing with Personal Data in the Age of Big Data Economies (2017)
Stevens, Gunnar ; Bossauer, Paul
The technological development of the digital computer and new options to collect, store and transfer mass data have changed the world in the last 40 years. Moreover, due to the ongoing progress of computer power, the establishment of the Internet as critical infrastructure and the options of ubiquitous sensor systems will have a dramatic impact on economies and societies in the future. We give a brief overview about the technological basics especially with regard to the exponential growth of big data and current turn towards sensor-based data collection. From this stance, we reconsider the various dimensions of personal data and and market mechanisms that have an impact of data usage and protection.
Investigating Car Futures from Different Angles (2019)
Stevens, Gunnar ; Meurer, Johanna ; Pakusch, Christina ; Bossauer, Paul
The design of self-driving cars is one of the most exciting and ambitious challenges of our days and every day, new research work is published. In order to give an orientation, this article will present an overview of various methods used to study the human side of autonomous driving. Simplifying roughly, you can distinguish between design science-oriented methods (such as Research through Design, Wizard of Oz or driving simulator ) and behavioral science methods (such as survey, interview, and observation). We show how these methods are adopted in the context of autonomous driving research and dis-cuss their strengths and weaknesses. Due to the complexity of the topic, we will show that mixed method approaches will be suitable to explore the impact of autonomous driving on different levels: the individual, the social interaction and society.
Mehrwerte auf Basis digitaler Kassenzettel: eine verbraucherinformatische Studie (2018)
Bossauer, Paul ; Hanschke, Stefan ; Stevens, Gunnar
Die Digitalisierung aller Lebenswelten wird das Kauf- und Konsumverhalten von Verbrauchern stark ändern. Es zeichnet sich ab, dass Zukunftsszenarien des Smart Shopping, Smart Kitchen und Smart Cooking zunehmend real werden und sich immer stärker verzahnen. Zurzeit finden sich z. B. Bestrebungen zum digitalen Kassenzettel. Der Beitrag zeigt, dass Verbraucher sich hierdurch eine Reihe von Mehrwerten erhoffen, z. B. dass sie eine höhere Transparenz ermöglichen, indem sie Zusatzinformationen zu den Produkten bereitstellen. Ebenfalls sollen die Informationen genutzt werden, Rezeptvorschläge zu den gekauften, im Haus befindlichen Waren sowie Auskunft über den Zustand der Waren bereitzustellen. Ein weiterer Bereich stellt eine bessere Kosten- und Ernährungskontrolle dar, indem die Daten des Kassenzettels automatisch in digitale Haushaltsbücher und Ernährungs- bzw. Fitness-Apps übertragen werden können.
Akzeptanz autonomer Verkehrsmittel: Eine Analyse relativer Mehrwerte selbstfahrender Autos im Vergleich zu heutigen Verkehrsmitteln (2018)
Pakusch, Christina ; Weber, Tobias ; Stevens, Gunnar ; Bossauer, Paul
Durch die Digitalisierung befindet sich die Mobilitätsbranche im starken Umbruch. So wird man bei der Verkehrsmittelwahl zukünftig wohl auch auf selbstfahrende Autos zurückgreifen können. Die Studie erweitert die Verkehrs- und Nutzerakzeptanzforschung, indem unter Berücksichtigung relativer Teilmehrwerte tiefergehend analysiert wird, wie sich die neuen Verkehrsmodi autonomer Privat-PKW, autonomes Carsharing und autonomes Taxi aus heutiger Sicht in den bestehenden Verkehrsmix einsortieren. Hierzu wurde auf Basis der Nutzerpräferenztheorie eine Onlineumfrage (n=172) zu den relativen Mehrwerten der neuen autonomen Verkehrsmodi durchgeführt. Es zeigt sich, dass Nutzer im Vergleich zum PKW bei den autonomen Modi Verbesserungen im Fahrkomfort und in der Zeitnutzung sehen, in vielen anderen Bereichen – insbesondere bei Fahrspaß und Kontrolle – hingegen keine Vorteile oder sogar relative Nachteile sehen. Gegenüber dem ÖPNV bieten die autonomen Modi in fast allen Eigenschaften Mehrwerte. Diese Betrachtung auf Teilnutzenebene liefert eine genauere Erklärung für Nutzerakzeptanz des automatisierten Fahrens.
The Users' Perspective on Autonomous Driving (2018)
Pakusch, Christina ; Stevens, Gunnar ; Bossauer, Paul ; Weber, Tobias
Digitisation has brought a major upheaval to the mobility sector, and in the future, self-driving cars will probably be one of the transport modes. This study extends transport and user acceptance research by analysing in greater depth how the new modes of autonomous private cars, autonomous carsharing and autonomous taxis fit into the existing traffic mix from today's perspective. It focuses on accounting for relative added value. For this purpose, user preference theory was used as a base for an online survey (n=172) on the relative added value of the new autonomous traffic modes. Results show that users see advantages in the autonomous modes for driving comfort and time utilization whereas, in comparison to conventional cars, in many other areas – especially in terms of driving pleasure and control – they see no advantages or even relative disadvantages. Compared to public transport, the autonomous modes offer added values in almost all characteristics. This analysis at the partwor th level provides a more detailed explanation for user acceptance of automated driving.

Shared Autonomous Vehicles: Potentials for a Sustainable Mobility and Risks of Unintended Effects (2018)
Pakusch, Christina ; Stevens, Gunnar ; Bossauer, Paul
Automated and connected cars could significantly reduce congestion and emissions through a more efficient flow of traffic and a reduction in the number of vehicles. An increase in demand for driving with autonomous vehicles is also conceivable due to higher comfort and improved quality of time using driverless cars. So far, empirical evidence supporting this hypothesis is missing. To analyze the influence of autonomous driving on mobility behavior and to uncover user preferences, which serve as an indicator for future travel mode choices, we conducted an online survey with a paired comparison of current and future travel modes with 302 German participants. The results do not confirm the hypothesis that ownership will become an outdated model in the future. Instead they suggest that private cars, whether traditional or fully automated, will remain the preferred travel mode. At the same time, carsharing will benefit from full automation more than private cars. However, findings indicate that the growth of carsharing will mainly be at the expense of public transport, showing that more effort should be placed in making public transportation more attractive if sustainable mobility is to be developed.
Using shopping data to design sustainable consumer apps (2018)
Stevens, Gunnar ; Bossauer, Paul ; Neifer, Thomas ; Hanschke, Stefan
The Internet of Things is greatly changing the buying and consuming behavior. Future scenarios of smart shopping, smart kitchen and smart cooking become increasingly real and integrated. In this context we see current attempts of creating digital receipts in the food retailing industry. Respectively to these attempts, this paper shows that consumers expect a number of added values from the digital receipt, e.g. a higher transparency for a better self-reflection, therefore a more sustainable food consumption and more information about the bought products. We conducted qualitative interviews to find out how people use receipts and what added values they can imagine in terms of a digital receipt to improve their consumption behavior and to reduce food waste. Since all bought products will be registered digitally, it becomes possible to use the shopping data for sustainable consumer apps.
Using, Sharing, and Owning Smart Cars (2016)
Pakusch, Christina ; Bossauer, Paul ; Shakoor, Markus ; Stevens, Gunnar
The megatrends towards both a digital and a usership economy have changed entire markets in the past and will continue to do so over the next decades. In this work, we outline what this change means for possible futures of the mobility sector, taking the combination of trends in both economies into account. Using a sys-tematic, scenario-based trend analysis, we draft four general future scenarios and adapt the two most relevant scenarios to the automotive sector. Our findings show that combing the trends from both economies provides new insights that have often been neglected in literature because of an isolated view on digital technology only. However, service concepts such as self-driving car sharing or self-driving taxis have a great impact at various levels including microeconomic (e.g., service and product design, business models) and macroeconomic (e.g., with regard to ecological, economical, and social impacts). We give a brief outline of these issues and show which business mo dels could be successful in the most likely future scenarios, before we frame strategic implications for today’s automobile manufacturers.
Auswirkung vollautomatisierter PKWs auf die Verkehrsmittelwahl (2017)
Wödl, Sebastian ; Pakusch, Christina ; Bossauer, Paul ; Stevens, Gunnar
Das autonome Fahren wird die Mobilität revolutionieren. Um die Auswirkung der Vollautomation auf dieEigenschaften der Verkehrsmittel und die Präferenzen der Nutzer besser zu verstehen, haben wir dieNutzenwerte neuen Verkehrsmodi im Vergleich zu den bestehenden Verkehrsmodi analysiert und imRahmen einer Online-Umfrage von potentiellen Nutzern in Form eines vollständigen Paarvergleichsbewerten lassen. Die Studie zeigt, dass der Privat-PKW, unabhängig davon ob traditionell odervollautomatisiert, zwar nach wie vor das präferierte Verkehrsmittel ist, im direkten Vergleich das Carsharingjedoch viel stärker von der Vollautomation profitiert. Darüber hinaus gibt es Hinweise darauf, dass dasvollautomatisierte Carsharing verstärkt in Konkurrenz zum ÖPNV tritt.

Mehrseitiges Vertrauen bei IoT-basierten Reputationssystemen (2018)
Stevens, Gunnar ; Bossauer, Paul ; Jakobi, Timo ; Pakusch, Christina
Vertrauen ist das Schmiermittel der Shareconomy. Einen zentralen Mechanismus hierfür stellen Crowd-basierte Reputationssysteme dar, bei denen Informationen und Bewertungen anderer Nutzer dazu dienen Vertrauen aufzubauen. Die Vernetzung zu teilender Gegenstände bietet hierbei neue Potentiale, um die Reputation eines Anbieters oder Nachfragers zu bewerten und einzuschätzen. In diesem Beitrag untersu-chen wir daher das Potential eines IoT-basierten Reputationssystems im Kontext von Peer-to-Peer Car-sharing, bei dem Informationen und Bewertungen mittels Sensorik während der Nutzung des Fahrzeugs erhoben und ausgewertet werden. Hierzu wurden zwei Fokusgruppen mit insgesamt 12 Personen durch-geführt. Die Ergebnisse deuten an, dass datenbasierte Reputationssysteme das Vertrauen nicht nur vor, sondern auch während der Vermietung und in der Nachkontrolle für Ver- und Entleiher steigern können. Jedoch sollten bei der Gestaltung solcher Systeme die Prinzipien der mehrseitigen Sicherheit wie Spar-samkeit, Verhältnismäßigkeit, Transparenz und Reziprozität beachtet werden.
Second Dashboard: Information Demands in a Connected Car (2017)
Stevens, Gunnar ; Bossauer, Paul ; Jakobi, Timo ; Pakusch, Christina
Traditionally automotive UI focusses on the ergonomic design of controls and the user experience in the car. Bringing networked sensors into the car, connected cars can provide additional information to car drivers and owners, for and beyond the driving task. While there already are technological solutions, such as mobile applications commercially available, research on users’ information demands in such applications is scarce. We conducted four focus groups to uncover what kind of information users might be interested in to see on a second dashboard. Our findings show that besides control screens of todays’ dashboards, people are also interested in connected car services providing context information for a current driving situation and allowing strategic planning of driving safety or supporting car management when not driving. Our use cases inform the design of content for secondary dashboards for and especially beyond the driving context with a user perspective.

Unintended Effects of Autonomous Driving: A Study on Mobility Preferences in the Future (2018)
Pakusch, Christina ; Stevens, Gunnar ; Boden, Alexander ; Bossauer, Paul
Innovations in the mobility industry such as automated and connected cars could significantly reduce congestion and emissions by allowing the traffic to flow more freely and reducing the number of vehicles according to some researchers. However, the effectiveness of these sustainable product and service innovations is often limited by unexpected changes in consumption: some researchers thus hypothesize that the higher comfort and improved quality of time in driverless cars could lead to an increase in demand for driving with autonomous vehicles. So far, there is a lack of empirical evidence supporting either one or other of these hypotheses. To analyze the influence of autonomous driving on mobility behavior and to uncover user preferences, which serve as indicators for future travel mode choices, we conducted an online survey with a paired comparison of current and future travel modes with 302 participants in Germany. The results do not confirm the hypothesis that ownership will become an outdated model in the future. Instead they suggest that private cars, whether conventional or fully automated, will remain the preferred travel mode. At the same time, carsharing will benefit from full automation more than private cars. However, the findings indicate that the growth of carsharing will mainly be at the expense of public transport, showing that more emphasis should be placed in making public transport more attractive if sustainable mobility is to be developed.
